Marcel-Paul Schützenberger
Marcel -Paul Schützenberger, Marco Schützenberger, ( born October 24, 1920 in Paris, † July 29, 1996 ) was a French mathematician.
Protect Berger's family came from Alsace, but went to the Franco-German war 1870/71 to France. His ancestors included the chemist Paul Schützenberger. Schützenberger studied medicine and mathematics in Paris. 1943 was his first mathematical publication on Dedekind rings. 1943 until the liberation of Paris in 1944 he was part of the Forces françaises libres of Charles de Gaulle.
After the war he continued his medical studies and received his doctorate in medicine in 1948. At the same time he continued his mathematical publications, eg on statistics, which he applied also in his research in medicine. 1948 to 1953 he was at the National Institute of Hygiene, where he was part of the team that discovered the trisomy. In 1953 he was in Paris a doctorate in mathematics with a thesis on communication theory by Claude Shannon. He conducted research in 1953 for the CNRS and worked in 1956 at the Laboratory of Electronics at the Massachusetts Institute of Technology, on the Shannon 1956/57, was a visiting professor. 1957 to 1963 he was professor at the University of Poitiers and 1961/62 Lecturer in the Faculty of Medicine at Harvard University. In 1963, he was Director of Research at CNRS and 1964 professor at the Sorbonne. In 1970 he moved to the University of Paris VII ( Denis Diderot ), where he remained for the rest of his career.
Schützenberger published many mathematical areas, for example in combinatorics ( such as Young tableau ), algebra ( semigroups, associations, etc. ), computer science (such as automata theory ) and statistics.
The set of Chomsky - Schützenberger (1963, also named after Noam Chomsky ) states that every context-free language is a simple Dyck language.
With his friend David Berlinski Schützenberger developed a mathematical critique of the Darwinian theory of evolution, according to which the speciation much more time looking through random mutations, as was available.
Schützenberger was a member of the French Academy of Sciences and the recipient of numerous other awards.
