Marc Julia (1922-2010)

French chemist, professor at the École Normale Supérieure in Paris. He worked mainly on the chemistry of free radicals and sulfones.
In 1973, with Jean-Marc Paris, he described the conversion of β-acyloxy sulfones into alkenes with sodium amalgam, the Julia olefination. His brother Sylvestre Julia, also a chemist, developed the modified version with heteroaryl sulfones.
