The French National Research Center (CNRS) has just awarded  its annual gold medal to Gérard Berry, a great recognition for an outstanding computer scientist. I first discovered Berry’s work through a brilliant 1976 article, Bottom-Up Computation of Recursive Programs , which explained recursion using methods of denotational semantics, and should really figure in collections of classic CS articles. One can hardly understand dynamic programming algorithms, for example, without realizing that they are bottom-up versions of recursive algorithms, through transformations described in the article. I relied extensively on its techniques for my own textbooks, from the advanced concepts of Introduction to the Theory of Programming Languages all the way down to the introductory presentation of recursion in Touch of Class.
Berry then went on to play a founding role in synchronous languages, explaining (in a paper whose reference I don’t have right now) that he went through a revelation of sorts after realizing that the automatic-control industry needed languages completely different from those computer scientists typically love. He created the Estérel language and shepherded it all the way to industrialization, serving as Chief Scientist of Estérel Technologies in the 2000 decade, before coming back to research.
He is also well known in France as a popularizer of informatics (computer science) through a number of successful books aiming at a large audience. He was appointed the first professor of informatics at the Collège de France, and in his inaugural lecture series presented a sweeping description of how information technology advances, based on powerful scientific concepts, permeate today’s world and raise ever new challenges. Hardly could the CNRS have chosen to distinguish a better representative of our discipline.
