Computer scientist gallery, updated

After several months of inaction I have updated my “Gallery of Computer Scientists” [1]. It benefits from many recent meetings where the density per square meter of Turing award winners and other brilliant computer scientists was hard to beat, most notably the two extraordinary Turing centenary celebrations  — the ACM event in San Francisco, and Andrei Voronkov’s Manchester conference — and our own LASER summer school of last September which brought together the Gotha of programming language designers. And I still have not included everyone.

I do not know of any photographic collection anywhere that compares to this archive in either quantity or quality of the scientists pictured. My only regret is that I did not start earlier (I missed several giants of the field, to soon departed, such as Dijkstra, Dahl and Nygaard, even though I had many occasions to photograph them). The truth is that I had got impatient with photography and started again only when digital cameras became widely available.

The quality of the pictures themselves varies. It is definitely higher in recent ones: I may have become a better photographer, but it does not hurt that I have more sophisticated cameras than the rudimentary point-and-shoot I was using at the beginning. I should also improve the layout of the page, although I hope you will appreciate the ability to move the cursor around to get large pictures without having to click and go to different pages.

I started this collection because it occurred to me that for a number of reasons I am, more than almost anyone I know, in the position of meeting outstanding people from many different sub-communities of software engineering and the rest of computer science: from program verification, semantics, languages, algorithms to architecture, management, empirical software engineering and many others. I realized that it would be unconscionable not to take advantage of these opportunities and do for computer scientists what Paul Halmos did for mathematicians [2].

Some of the people pictured are more famous than others, but all do interesting work. There is no profound logic to the choice of subjects; it obviously depends on the chances I get, but also on the time I can spend afterwards to sort through the shots (this is not a full-time job). So if you know I took a picture of you and you do not see it on the page, do not take offense: it may be a matter of time, or I may need another opportunity and a better shot.

All the pictures are by me. They are of different styles; I try to capture a personality and a mood. Many shots show a computer scientist in flagrante delicto: doing computer science, as when giving a talk, or engaging in a design discussion around a laptop. Some were taken in more informal settings, such as a long winter walk in the woods. A few reveal some humorous or fancy aspect of the subject’s personality. None has any context or explanation; I will not tell you, for example, why Tony Hoare had, on that day, two hats and two umbrellas. I think it is more fun to let you imagine.

Pictures are only pictures and what matters is the work that all these great people do. Still, I hope you will enjoy seeing what they look like.
