Marcel-Paul "Marco" Schützenberger (October 24, 1920 – July 29, 1996) was a French mathematician and Doctor of Medicine.
He worked in the fields of formal language, combinatorics, and information theory.
In addition to his formal results in mathematics, he was "deeply involved in [a] struggle against the votaries of [neo-]Darwinism", a stance which has resulted in some mixed reactions from his peers and from critics of his stance on evolution.
Several notable theorems and objects in mathematics as well as computer science bear his name (for example Schutzenberger group or the Chomsky–Schützenberger hierarchy).
Paul Schützenberger was his great-grandfather.
In the late 1940s, he was briefly married to the psychologist Anne Ancelin Schützenberger.
