André Blanc-Lapierre

from Wikipedia, the free encyclopedia

André Joseph Lucien Blanc-Lapierre (born July 7, 1915 in Lavaur (Tarn) , † December 14, 2001 in Châtenay-Malabry ) was a French mathematician and physicist.

Blanc-Lapierre studied at the École normal supérieure (Paris) and worked under the physicist Georges Bruhat with the theory of shot noise with application to the measurement and amplification of small photocurrents, which led to his first dissertation in 1944. His mathematical treatment of the subject soon led to his doctorate in mathematics with Robert Fortet at the Sorbonne in 1945 (Sur certaines fonctions aléatoires stationnaires et applications à l'étude des fluctuations dues à la structure électronique de l'électricité). 1950 to 1961 he was professor of physics in Algiers . During this time, he expanded probabilistic methods such as correlation functions into optics (which only later became standard in the context of laser physics). He then headed the particle accelerator laboratory in Orsay as the successor to Hans Halban and was significantly involved in the 600 MeV Electron-Positron Collider (ACO) in Orsay (he entrusted Pierre Marin with the implementation, from 1963). He also invited the bubble chamber expert André Lagarrigue to his laboratory in Orsay, who became known through the Gargamelle collaboration at CERN. Most recently he was director of the École supérieure de l'électricité (SupElec).

He dealt with stochastic processes with applications in electronics, statistical mechanics, information theory and signal theory, accelerator technology, photocell amplifiers and radar. His book on stochastic processes with Fortet has been translated into several languages.

He was a member of the Académie des Sciences (from 1970, 1985/86 he was its president) and the Pontifical Academy of Sciences (1978). He was Grand Officer of the Ordre national du Mérite (1989) and the Legion of Honor (1992), President of the Comité Français de Physique in 1969 and of the Société Française des Electriciens in 1971 and of the Société Française de Physique in 1981. From 1987 to 1990 he was President of the Conseil Supérieur de la Sûreté et de l'Information Nucléaires.
