A Tribute from Stephen Wolfram

October 18th, 2010

Stephen Wolfram wrote the following tribute to Robby.

With the tragic death of Robby Villegas, the world has lost an exceptional mind, and one of the great scholars and guardians of the Mathematica language. It was June 6, 1992, on a pleasant sunny day, just after an honorary degree ceremony at Knox College in Galesberg, Illinois. An eager young man who had just received his own degree came up to me, keen to tell me that he thought that the design of the function Outer[] in Mathematica was inadequate, and needed to be enhanced. We talked for quite a while. And eventually I said, “So what are you doing now that you’ve graduated? We’re hiring people at our company to work on Mathematica; you should come and join us.” And so it was that on June 29, 1992, Robby Villegas came to join Wolfram Research.

In the 15 years that followed, my email archive records more than 10,000 messages that include his name, with the number peaking in 1995. The syntax and semantics of a zillion functions. Ideas for extending, generalizing, clarifying features in Mathematica. A vast amount of work concerned with getting things in Mathematica just right. In making everything as clean and logical as it could be. In many ways, Robby Villegas was the first full-time design analyst for Mathematica. I think he personally knew every function in the system—its character, and its quirks.

And pretty soon when people were discussing some abstruse (or not so abstruse) potential feature of some new Mathematica function, I would just say, “Ask Robby; he’ll be able to figure it out.”

Robby Villegas contributed a great many ideas to Mathematica. To list manipulation and functional programming operations. And to mathematical typesetting, and the MathML web standard.

We have been lucky enough with Mathematica to be able to build a very pure and robust intellectual structure, that we can progressively add to over the years. Robby Villegas was the architect of some of the most demanding and elegant sections of this structure.

I remember one day when we were discussing some function or another, and someone was saying that we should do something in a particular way, because that’s how some other function in Mathematica worked. And Robby Villegas said that perhaps that precedent was not so good, because that other function was designed very early in the history of Mathematica, when designs were rougher.

And in that moment I realized that Robby Villegas had become the first true scholar of the Mathematica language. With an understanding not only of its current structure, but also the whole arc of its history. With his eagerness, he seemed in many ways so young. But yet he brought to his judgment about Mathematica a certain seasoned wisdom.

Over the years, I worked on many projects with Robby Villegas. From all sorts of detailed pieces of Mathematica design, to the emergency need to produce Mathematica code for notation for numbers and polynomials from antiquity (code that lives on for example in Wolfram|Alpha).

In later years, there were times when it could take a while to hear from Robby Villegas. But always the responses were careful, clear, and creative. And profoundly committed to making sure that the Mathematica language that we have all created remained as elegant and unified as possible.

There are countless specific functions in Mathematica that owe their structure and syntax to Robby Villegas. And as the system grows, these functions become the cornerstones of yet more development—building on the legacy of Robby Villegas.

Every day, around the world, people use those functions that Robby Villegas designed. And though all will benefit from it, few will pause to admire the elegance of the design. Or know about the wonderful human being who put so much effort into creating and ensuring that elegance: Robby Villegas, a great scholar and guardian of the Mathematica language, and its first true design analyst.

    I remeber Robby from middle school he was one of the nicest boys i had ever met, he was brilliant! I always had trouble in math and Robby was always there to help me out, I wouldnt even have to ask him he would gladly volunteer to help me, i had just recently found him again on facebook, he was truly one of the sweetest people i know he will be so missed….

    Robby was one of my first friends when I began work at Wolfram. I just learned of his passing today..on his birthday & Thanksgiving. I’m very thankful for having him as a friend. God Bless.

  4. Stephanie Barkin Says:

    I met Robby on Orkut several years ago – he’s the only person I kept in touch with from that networking site. There was something so special about Robby, and I really valued his friendship. I’m going to miss hearing him call me “Stephanova.” And who is going to warn me when I about to stumble upon a photograph of a praying mantis? Rest peacefully, Robby.

  5. David Cunningham Says:

    The brain may die, but I believe one’s mind is eternal. It is our link to the consciousness of the universe, which is a living, breathing Thing. Thought energy, synchronicity, deja vu, dreams; I believe a part of Robby is still with us. Our energy goes on.

  6. Patrick McGraw Says:

    Robbie was truly fun to work with. I believe he was one of the few developers who actually never needed a Macintosh on his desk. Many others needed to see “the Mac Front End” to get things right. Robbie never did.

    His dry sense of humor, his clear observations and his sensibilities were a gift to us.

    We’ll miss you, Robbie.

    –Patrick McGraw, WRI SysAdmin, 1989 – 1997

  7. Robert Naiman Says:

    I just heard this news yesterday. Ouch. Robby was one of my favorite people at WRI – you could have a nice and engaging conversation with him about Mathematica, and you could also have a nice and engaging conversation with him about the world outside of Wolfram Research. I saw him as soft-spoken but not withdrawn – he followed politics, and when I organized a contribution from WRI employees to Christian Peacemaker Teams in memory of Jerry Keiper, he made a contribution.

    I did not really keep in touch with Robby after I left WRI, but I would see him occasionally around town and I was under the impression that he was doing ok. Needless to say, I’m doubly sorry for this news; sorry to learn of his passing, sorry to learn of his torment.

    A thoughtful, caring, and gentle soul. I will miss him.

Summer by Kathy Villegas

October 17th, 2010

Summer

My poem — a mute soliloquy –
Transposes to air
And soars on soundless melody –
A chord — not found in harmony –
Consonant with light –
Perceives its finite transiency
Augments to flaming urgency –
Diminishes to minor key –
Then falls to darkest mode
In sudden brilliant agony


— Mom

    I knew Robby very briefly at Knox college. I believe he was a TA for one of my math classes, and the guy was brilliant. As an 18 year old, I wish I had the maturity to reach out to him more. I also wish now as a physician that I could have met him, have him open up to me, and treat him with the right dose of antidepressants. I wish him peace, and am saddened to hear of his death.

    Re: Parking during the Memorial
    As Wesley United Methodist Church is on campus, parking can be an issue. The parking lot at Wesley is available all Saturday for us to use. (It has “private parking only” signs, but those don’t apply to people using the building for an event.) However, it is a small parking lot and it is possible we will fill it up. If the parking lot is full, please remember that the parking meters at the nearby street parking *will* need to be paid on Saturday. Those who know campus may be able to find parking in the various University parking lots, as many of those are only rented Monday through Friday. Please read the big blue signs at the parking lot entrances carefully, as I don’t want to cause anyone to get a parking ticket.

    I did not know Robby. I am a good friend of Robby’s mother Kathy we went to Galesburg High School together and share the love of dolls. I just want to let Kathy and her brother know that I am thinking of them in this dark hour. Remember God has a plan and it is not always our plan. My God be with you both. Love, Mary and Dan

  4. Anne E Says:

    I was just a beginning adult skater, and I was sooo incompetent, but Robby always had an encouraging word and a few pointers and a comment about my improvement (even if it would have taken a microscope to see the improvement). Disgusted with my lack of progess, I eventually stopped skating, but I’ve never forgotten Robby or how often he was kind and helpful to me and others at the rink. Some days I’m sure he would have preferred more time working on his own skating, but he still always took the time to help me, and to chat a while, and to skate around the rink for a few laps with me whenever I was there.

    I’ll never forget his calm controlled deep edges as he did dance patterns or other moves around the rink – of all the adult skaters out there, Robby’s edges to me were the loveliest works of art – sometimes I would just pull over to the side and watch him. This will be how I remember him, skating those beautiful patterns, completely in control of his blades, dressed in black on the brilliant white ice, swooping confidently around the rink, a joy to watch.

    My heart goes out to his family and friends.

Remembering Robby

October 5th, 2010

Welcome.  This is a place for us to celebrate the life of our amazing friend, Robby Villegas.

Please add your thoughts and share your memories.

I’ll start…

Robby and I went on a photo walk around Homer Lake around this time last fall.  I took this photo of him and titled it “Robby Gets the Shot”.  He was hanging off the edge of the pier with his face (and expensive camera) just a few inches from the water. We had a lot of fun that day, sneaking up on all sorts of unsuspecting wildlife who were busy getting ready for winter.  We captured summer’s last gasp of breath before the cold set in.  We spent a ridiculously long time watching a spider stalking an ant on a picnic table.  The ant would wait until the spider got very close and ready to pounce, then he would very casually walk a few inches in the opposite direction and the dance would start all over again.  The ant had wings, so we decided that he was just having some fun at the spider’s expense and would eventually fly away.  But we got tired of watching before they got tired of playing their game.

Robby, I will miss you terribly.  You had such a beautiful, childlike way of looking at life.  I didn’t get to spend enough time with you before you left us.  I hope you are at peace now.

~Michelle Darling

    Words fail me. I was beyond shocked when I heard the news. Robby was an integral part of my time in Champaign … it is virtually impossible to think of one without the other. He will certainly be missed.

  2. Euan Fernsler Says:

    Well my friend, thanks for everything from college onward – including all you did to help us move to Illinois and meet all the fine new friends there.

    Aside from all the hard to explain friendship experiences over those many years, I want to thank you particularly for teaching me VI. It may not have seemed like much at the time, but giving me the VI book did more to help me than anything else. I did not reference it much, but I did use it as a mental crutch and never properly thanked you for it.

    Enjoy your next life more than your last, and with a little luck we shall meet again!

  3. Lynda Sherman Says:

    I don’t have a lot of coherent words yet, just a large knot and a much larger aching emptiness (and an awareness of what Robby would make of that statement). Here are my only photos of him in electronic form. The hat is Sarah’s, from the day Sarah and John moved into their Hessel townhouse. I think the shadowed one is from The Bread Company, where Robby and I liked to share dinner followed by lemon mousse. In the last one, he’d just put on a purple headband of mine to haul his hair back from his face. All were taken with a several-years-old phone camera, I’m afraid.

  4. Elisha Andeson Says:

    Robby and I had recently reconnected on Facebook after going to Galesburg High School together. We just spoke a couple of weeks ago about our mutual love of macro photography after he uploaded some beautiful new pictures. He was the smartest person I’ve ever known and a sweet and gentle soul. It is very sad to think he was in so much pain. I know he will be greatly missed.

  5. Britt Says:

    Words cannot communicate the profound impact Robby had on my life. He is one of the most loving, whimsical, authentic, brilliant, and beautiful men I have ever known. My heart is in a complex knot of hurt, agony, and pain right now. I wish he had told me how desperate his situation had become. I had the great privilege of dating him a year and having him as a friend. We shared so many similar characteristics and histories, and this bonded me to him for life. I will never forget the tenderness of his heart, his hands, and his soul.

    Robby: I don’t know how to say in words how deeply you will be missed by me. I know you are now aware of my feelings of love, loss, and sadness. Forgive me, dear friend, but I also feel some anger as I wish you had reached out. So many loved you. I would have done anything within my powers to stop your suicide, and I know there are hundreds of people whom would have wanted to do the same. Just, please, know I love you. Please feel my love and the love of all the wonderful people who call you friend.

    Two days ago, I woke with the sensation of holding your hand in mine. I pray it was real. Your hands were delicate and fine, and I needed to feel your hand that morning after hearing the news of your death. You are loved. The attached picture is one I took of you (as you know) when you visited me in New Mexico. I love this photo. Your eyes are so bright and full of mirth. This is how I wish to always remember you: Tender, funny, brilliant, and loyal. I love you, dearest Robby. Always and forever.

  6. Altaire Says:

    I made him snort pop out his nose.

    we made each other laugh.

    So gentle, spiritual, talented …

    He left an invisible mark on my soul.

    The wrong person left the party early and now it sucks.

    much love, Robby. always. no time limit, I swear.

  7. dave conroy Says:

    I just recently reconnected with Robby after having gone to Knox College with him. I still remember when I first met Robby. I had taken Calculus in high school and thus signed up for discrete math with Professor Borden as my first math class at Knox. We introduced ourselves (it was a small class and we went in alpha order). By the time most of the class had introduced themselves I was scared out of my mind as I was the only freshman in the whole class. then Robby introduced himself and he was a fellow freshman. I thought, this won’t be so bad. Well, he ended up being our TA as well as taking the class. I worked my ass off but I never would have gotten the B I got without him. Robby was totally brilliant. We went on to be great friends in a very small department. I still remember when I finally came out as gay to him and the rest of my roommates in senior year. I had been sort of backed into a corner but came out. When I was done he said “No Dave you’re a bisexual” He thought I had to have been attracted to women I had lied about it so much. That was Robby both brilliant and assigning the best of motives to people. Like everyone else he accepted me without question. Without him, Ted, Max, Carl, Pete, and Mike I don’t know if I would have made it back then. I just wish I had been there to help him this time.

    The world is poorer tonight for Robby’s absence.

  8. Cindy Adania Says:

    Robby and I worked for Wolfram Research and met there. We shared a love of bugs and photography.

    I was happy that we reconnected recently on facebook…and enjoyed the electronic banter. I liked his sense of humor.

    I am stunned…and deeply saddened.

    Robby wanted to “give some explanation to people in general” and asked me to post this, which he wrote. -Christina

    Subject: the end is important in all things

    Robby Villegas October 2 at 7:17am

    Depression, and even more so, physical exhaustion, continues to claim more and more of my life, to render a larger percentage of each day either unusable, or a sloggin, dragging fight to keep myself upright just to get through the basics of my day. On top of fatigue, a few years ago I began to develop a tendency toward anxiety, which gradually became more frequent and of faster onset, throwing a specter of borderline panic attacks over many of my activities. Eventually, I was taking partial doses of my prescription sleep medication *preemptively* before simple activities like skating class, meeting friends at a bar, going to a theater, or spending an evening studying at a cafe.

    The sleep and exhaustion problems that forced me to suddenly quit working in January 2007 have gradually worsened, and I have run out of means at this point.

    More important than financial means, though: the ratio of quality of life to pained struggling has passed a threshold. Eventually, I’ll forget what it even felt like to be happy, the memories of what I was will fade further, I won’t be able to appreciate any of the good parts of life, and I’ll be bitter, not even a shadow of my self.

    This must not happen. For many years, I have felt that some day I’d have to make that call that it’s time to go; that most of the good stuff was past, and the proportion of hope and new joy to the pain and effort that goes into rallying would fall too low I want to go out while I can still reflect on the good things, and go out really feeling and believing “I lived.”

    Worse than the death of the body is the death of pieces of the self while still alive, and the memories that provide conviction that there was a lot worth being here for, while it lasted.

    In retrospect, I probably should have made this call last winter, or at the very latest, early summer, given that the last few months have had a marked dulling effect on me. But, two decades of fighting depression, rallying through many dozens of life-hating and self-hating episodes ranging from bad patches to truly close calls, and being thankful I did each time I got a “new lease on life” that was followed by more of the worthwhile stuff of life … two decades of that makes it *intensely* difficult to make that final call.

    Albeit more weary and dull than I’ve ever been, I am thankful that there’s enough left of me to look back (even with difficulty) and appreciate all the good people, activities, and interests that made My Life worth living during that time. So it is perhaps not too late to exit while there’s a reasonable amount left of Me.

    Yours in truth,
    Robby “R. Scott”

  13. Debby LeVeck Says:

    Last spring Robby made it over to Danville for a Practice Ice session & it breaks my heart that I was busy teaching and didn’t have more time to visit with him. How often do we miss these precious moments to cherish the life of another… I wish that he could have found enough reasons to make the struggle worth while, yet it pains me to only now find out that he was suffering so.

  14. Patty Says:

    I think of Robby on the ice, skating with beautiful posture and always, in his word, with absorption. I remember that when I came back after my accident he came racing across the ice and gave me one of the biggest hugs I’ve ever had. Goodbye, Robby. Thank you for being my friend. I’ll miss you. I wish you peace.

  15. Tim Skirvin Says:

    I posted what I could on my own blog, and linked to here, but, in short:

    Robby was a good man. I will miss him. And I hope that he was right, that he is better off now than he would have been.

    May your afterlife offer all of the sights and lenses that you may need, my friend. Goodbye.

  16. Anonymous Says:

    I met Robby at Wolfram Research in the early 90′s when I was still at the U of I, and he was definitely one of the good guys. One of the smartest people I’ve ever met, yet bound with a quiet humility. Even though I was a lowly student working on an academic project, he treated me with the respect I felt I hadn’t yet earned. And when I started work at Wolfram, he became a friend as well as trusted colleague.

    Sadly, we lost track of each other after I moved away. Fortunately, Facebook allowed us to connect again. In our recent conversations, he never burdened me with any his difficulties, but he would continually offer advice to myriad of issues in my life (most of which seem so trivial now).

    To echo many other comments here, I also hope that he’s better off. But for certain, the world is a little less bright without him in it.

  17. Leland Ray Says:

    I last saw Robby last Christmas. I was flying into Midway, and then making the trek down to Champaign. I met a friend in Chicago who dropped me off at the Kankakee Dennys. Robby picked me up there.

    Over the next few days we studied in coffeeshops, and walked the trail, just like we used to when I lived in Champaign.

    Rest well, friend.

    I am grateful for this site. And like many, I wish Robby had reached out more for help. But I am sure that’s easier said than done. I’m glad he found so many interests, friends and hobbies to add some spice to life. Robby, I will always treasure our badminton games in the backyard of your grandma’s place. I am so glad I could see you 2 years ago with my wife at U of I. Peace to you, my dear friend.

  21. Laura Hastings Says:

    I am so deeply saddened. My contact with Robby was at the ice rink, I could see skating was one of his passions, an outlet, a personal accomplishment. A peaceful soul who was a pleasure to talk with. He was kind to my two daughters who are younger skaters. We have known him for many years at the rink, I have marveled in Robbys commitment to progressing through the level of skating. We will miss his smile and total concentration to his skill. Peace be with you and all who loved and knew you.

  22. anon Says:

    I had not spoken to him since high school, but of course remembered him fondly. When the website popped up and I saw his face, I just thought, “Wow I just loved that guy!” Very sad…

  23. Jeffrey Robinson Says:

    Robby’s grandmother Doris Gilmore and my grandmother Irene Gensini were good friends. When I was in 8th grade (1982) I stayed with my grandmother during spring break. At that time, I met Robby, Davey McDonald, Bryan Hagerla, Dana Collis, Valerie Reaves, Jana Reiss, Suzy Hayworth, Carl Roy, and Diedre Ponzer. We all kept in touch and got together 3-4 times a year throughout high school, college, weddings etc. We always had such a great time no matter what we did. It was a group of people that would not normally hang out together always got together when I came to town. He produced some life long friends Robby started all that!

    He was always a much better student than I. His honors always motivated me to do better with my own studies. He accomplished a lot after college too with his work at Wolfman research. He was always modest about his accomplishments, but I beleive he did most of the work on a popular program that I’ve used for many years called ACT! – contact management….something that has been copied over and over.

    I will cherish all the great memories of Robby.

  24. Matt Pestle Says:

    Once again (through the note via Christina) Robby explains a difficult problem and will leave me scratching my head trying to figure out how it all fits together. Anyone who hung around the Knox Mathematics dept in the late 80′s will understand that feeling well, and I suspect those of you who knew him before and after that period will too.

    Sharing an office/study with him for three years during those formative years of our lives was quite possibly the most valuable part of my mathematics education. I used to try to convince myself that his spending huge amounts of time to patiently explain hard things to me might have helped him understand them better too, but I’m sure that wasn’t true – He just had a big heart, a sharp mind, and a genuine desire to help.

    I think that some solace can be taken from the knowledge that he would have thoroughly analyzed this problem, even and probably especially taking into account the impact on those he left behind (although modestly underestimating it, no doubt). His pain would have been immense.

    He was never one to turn his back on a hard problem, and it depresses me somewhat to wonder if his solution here was optimal (as his solutions to problems generally were). May we all do what we can to find better ones.

  25. John Williams Says:

    Robbie seemed to be all together, but low key. In his skating, he looked for positives in his own progress as well as for others. As Matt says above, it’s difficult to comprehend what was going on in that brilliant mind.

    A favorite memory: A stunning Dracula at Learn-to-Skate for Halloween.

  26. Carl Says:

    Robby, you are greatly missed. Rest in peace.

  27. Anne E Says:

    Oops sorry posted this in the wrong place – I’ll try again.

    I was just a beginning adult skater, and I was sooo incompetent, but Robby always had an
    encouraging word and a few pointers and a comment about my improvement (even if it would have taken a microscope to see the improvement). Disgusted with my lack of progess, I eventually stopped skating, but I’ve never forgotten Robby or how often he was kind and helpful to me and others at the rink. Some days I’m sure he would have preferred more time working on his own skating, but he still always took the time to help me, and to chat a while, and to skate around the rink for a few laps with me whenever I was there.

    I’ll never forget his calm controlled deep edges as he did dance patterns or other moves around the rink – of all the adult skaters out there, Robby’s edges to me were the loveliest works of art – sometimes I would just pull over to the side and watch him. This will be how I remember him, skating those beautiful patterns, completely in control of his blades, dressed in black on the brilliant white ice, swooping confidently around the rink, a joy to watch.

    My heart goes out to his family and friends.

  28. Andre Kuzniarek Says:

    Robby did the math.

    He applied a cold and unforgiving calculation to a warm and generous life.

    There was no mistake from his perspective, but surely he missed a variable? He could have reached out, he had friends, people who really cared about him, people who reached back in his direction. There are therapies, modern drugs, counselors, and other professional services and potential remedies for anything that ails us. We want to fix you so you can be happy and we can be happy — yay, we all win.

    But the reaching, the offers of help, or a need to ask for help are proof of a problem, feeding a dark and stubborn intuition for resolution. Whatever the calculations, whatever the variables, there is a looming, overriding constant that imposes the same unforgiving conclusion with its terrible solution.

    It must be the calculation of all who take this path. Must be the same for the disheartening number of people I have known who have taken it. I can try to imagine this looming constant, and there are times when I truly see it, or discover it again, but somehow the other variables in my life diminish its impact. I can relate, and yet I can’t.

    Isn’t life short enough? Isn’t there always some new discovery about the world around us worth waiting for? Aren’t there so many questions to seek answers for that even an endless lifetime might not be enough?

    I can only hope Robby has access to all the answers now. I will imagine him exploring the universe and yet also listening to me as I continue my unrequited conversations with him.

    I met Robby at Wolfram Research in 1996 when I worked as a temp for him. He had an injury and couldn’t type, so I typed for him: math formulas. Only he could have made this experience a pleasant, memorable one. We later reconnected through Facebook and occasionally shared experiences and passion for interesting bugs. I decided to check out his Facebook page this morning–noticed a new profile picture and always enjoyed his humor and quirky intelligence. What a spirit and what a loss.

  31. P.J. Hinton Says:

    Robby was one of the first employees I met at Wolfram Research when I started on January 8, 1996. I was working in Technical Support, a department where Robby himself had started with the company several years before. When I transitioned from support to development June of 1997, my first project was taking over TeXSave[ ], a feature that Robby had originally developed.

    Over time, we accumulated a large number of conversations on subjects ranging from work (math and computer science) to everything else (women, politics, philosophy, skating, etc.). Sometimes they were impromptu discussions in the workplace. Other times it was during dinners out. I remember us going out for Thai, Italian, and Papa Dels on nights when I had to stay over for on-site visits. I enjoyed his company, and I consider myself lucky to have known him.

    He was one of several people at Wolfram who helped shape my views on the design of APIs and the importance of a consistent convention on naming things. In subsequent jobs, I’ve gotten remarks from coworkers on my insistence on good nomenclature. That’s one of the countless ways that he touched and influenced others. And it is through these memories and marks that his spirit carries on.

    I learned of his passing a week ago via a phone call from Carl Roy, who introduced me to Robby at Wolfram. I was left speechless, and in many ways it is hard for me to wrap my mind around the grief that my heart feels.

    I knew of his battles with sleep. I knew that he had stopped working a couple years ago, but I didn’t keep in touch. I can’t help but feel that by not doing this, I failed him… perhaps holding out the illusory hope that had I done so, that might have rebalanced his life equation so that he would have carried on. I know that in reality, it is not that simple. It never is.

    It would be the height of folly to assume that the pain and suffering another endures is always bearable, given the right medication and coping tools. Although medicine has made strides in understanding the causes of depression and other disorders, the diagnosis and treatment is more art than science. Beyond the therapeutic, we all have our non-negotiables. As Andre Kuzniarek so put so well in a prior comment, he did the derivation and determined that these things could not be met.

    As his friend, I respect his choice, but deep down I wish that he would have stayed true to his field of study and put his thesis up for peer review before acting on it. Perhaps someone could have offered a rebuttal that would have helped him see another way.

    May peace be with you always, \[Villa]

    I don’t really remember exactly how Robby and I met, but given that he started within 6 months of me it’s no surprise. Back then everybody knew everybody. We probably had many interactions with him being in Tech Support. He was a very sweet and kind guy. Always had a smile and a hello. The biggest thing I’ll remember about Robby, aside from his love of skating, is that he never forgot my birthday. Usually it was just a quick note, but one time I got one of those chocolate orange things. The kind that’s wrapped in blue foil and it breaks apart into orange pieces made from chocolate. Yum! Thanks for all the birthday wishes, Robby. They were always appreciated. You will be missed by many.

    I have never been able to put my thoughts in a coherent manor, but Robby could always make sense of them anyway.
    I met Robby at a time, where I was admitting to myself a lifetime of hurt, and learning how to turn it into something positive.
    We had a lot in common, and we understood each other in our joy, pain, humor, and art.
    Even though we parted ways, he contributed greatly to the person I am today.
    I thank him for loving me in my pain, and giving me the strength I needed to Grow.
    Thanks to Robby and the wonderful circle of friends he connected me to I will never again take my life for granted.
    Thanks to Robby, I know I can do anything (like learning to jump in my first year of skating).
    Robby taught me a lot of the secrets of how to live.
    I wish that Robby’s story was different. I wish he had been able to make more joy of his sorrow.
    He fought for a long time, and was a strong and admirable soul.
    Robby’s body may be gone, but I find it evident in this site how much of an impact he made in this world.
    Though we parted ways, he contributed greatly to the person I am today.
    Though we parted ways, he is a reason I am alive today.
    Whether or not it is spoken, it is known,
    That all of my accomplishments may not have happened if not for the two years we spent together.
    I wish Robby’s story was different, but I am thankful that he welcomed me into it, and I know he lives on.
    These thoughts may be hard to decode, but I know that now, Robby understands them.
    I am thankful for Robby’s time here with us.
    I am thankful for his lesson, and friends that he shared with me, so I could live.
    Robby lives on.

  34. Richard Phillips Says:

    Very sad indeed to hear that Robby is gone.

    I remember a warm, humorous, and intelligent person who welcomed me when I was an intern at our employer. I believe he did that because he liked people, and showed genuine interest in them.

    Feel lucky to have met him, What a great person!

  35. Josh Says:

    I met Robby shortly after starting work at Wolfram in 2001. I was a Help Desk whipping-boy. Robby’s Linux box was having video problems and I was asked to fix it. It turned out to be a fairly simple driver issue, but from then on Robby and I would continue to interact…Not cause we had to for work, but because we had common interests.

    Robby started occasionally showing up to a local Tuesday-night gathering we lovingly called “Beer Tuesday” at the Office in Urbana, then at Crane Alley after the Office closed. He was always interested to talk to on subjects ranging from photography to politics to computer science and everything in between.

    Robby continued to infrequently attend Beer Tuesday after he stopped working. We were always happy to see him. We’ll miss him greatly.

  36. Tobias (Toby) Weingartner Says:

    First I thought this was a joke. Then as I realized it was not, I got pissed and angry. I know that if anyone would want me not to be angry and pissed, it would be Robby. Seriously not cool. RIP Robby, even though we only talked briefly over the years since I was at Wolfram, I always thought of you as a friend and a brilliant mind.

    This seriously sucks, and I can only hope that wherever your spirit is, it is in a better place. I now have two times a year where I will raise a glass to a person dear to me gone. I miss you Dude.

    i’m very saddened to hear this.

    Robby is one of my best friend, if not the closest who we exchange deep personal feelings.

    i met Robby face to face when i was intern at Wolfram in 1995. Before that, we were acquaintances on comp.soft-sys.math.mathematica. He became my personal friend, as well as being my guide to the company, the town, and taught me a huge amount of Mathematica.

    after 1995, we have kept in touch most of the time. Last major exchange happened during 2004-2005, when we were exploring the social networking and IM chatting on orkut.com and yahoo etc.

    in mid 2000s, he told me about his insomnia problems and stress. Though, i never gussed he’s got depression problems back and so bad. I never have guessed he’d take his life.

    Robby is extremely sensitive to stress and pressure. He’s the type of nice guy who find it hard to say no, and when he actually had to, it’s after huge mental struggle.

    gosh… what to say, you are dead Robby. We could’ve chatted about language design, porn, problems of life, and so much more. What about your studies of C? and the desire to know more math?

    though, i guess after reading robby’s goodbye note “the end is important in all things”, am not sure what to say. Such a engineer attitude. I guess i couldn’t help but repeat “the end is important in all things” too, as Andre puts it “Robby did the math”. Yeah, the ending is important, but this ending doesn’t seem to be a good one.

    thanks to robby’s family & friends for this page. I miss robby very much.

    Xah

    I met Robby on Orkut several years ago – he’s the only person I kept in touch with from that networking site. There was something so special about Robby, and I really valued his friendship. I’m going to miss hearing him call me “Stephanova.” And who is going to warn me when I about to stumble upon a photograph of a praying mantis? Rest peacefully, Robby.

  39. Ronald Monson Says:

    I’ve only just stumbled across this news.

    I only met Robby once but some people leave an impression more than most.

    Like many Mathematica users I had Robby’s “controlling evaluation” tutorials pretty much on tap when first learning mathematica. Fast forward a few years and I spent 3 months at WRI in 2001, a long way from home, but one night went to a party for WRI employees that was on at his place. I was keen to meet Robbie given how formative his tutorials and posts had been in my mathematica education. Our discussions about language design were some of the most illuminating and profound I’ve ever had – I remember thinking at the time – how is it that this guy’s ideas aren’t better known? – I guess this just showed what a humble guy he was.

    I’m surprised at some of the tributes saying what an “extremely keep-to-himself” person he was because the other thing that has always stuck in my mind was how friendly and welcoming he was to an out-of-towner.

    Really sad to hear this news.

  40. No one in particular Says:

    I knew Robbie from Knox. He was good in his department as I was in mine. His just happened to be pretty damned tough, unlike mine.

    We were not great friends, but he was most enjoyable to run in to. He was funny, friendly and empathetic. I always felt he measured his words carefully before the said them (unless it was a corny joke or pun, which he was free with when he had one).

    Thank you all for being part of his life and sharing neat things with him. You probably took the best care of him you could. Thanks.

  41. Michelle Darling Says:

    There is a chill in the air today, and the smells of autumn filled my mind with thoughts of Robby.

    He was my cousin.. so sad now :( (((((
