*[Notice: This post is fairly “local” in that it is about a long-time friend being celebrated by his university. Nice poster though and an opportunity to stress his essential contributions to the maths department there!]*

**N**ext June, I will spend the day in Rouen for a conference celebrating the career and dedication of Gérard Grancher to mathematics and the maths department there. (When I got invited I had not realised I was to give *the* research talk of the day!) Gérard Granger is a CNRS engineer and a statistician who is indissociable from the maths department in Rouen, where he spent his whole career, now getting quite close to [mandatory] retirement! I am very happy to take part in this celebration as Gérard has always been an essential component of the department there, driving the computer structure, reorganising the library, disseminating the fun of doing maths to high schools around and to the general public, and always a major presence in the department, whom I met when I started my PhD there (!) Working on the local computers in Pascal and typing my thesis with scientific word (!!)
