Aleksei Chichibabin (1871-1945)

Russian chemist, professor at the Higher Technical School and the University of Moscow. He was one of the founders of heterocyclic chemistry: in 1914 he described the amination of pyridine with sodium amide that bears his name, and in 1924 a synthesis of pyridines from aldehydes and ammonia that is still used in industry. He also studied triphenylmethyl free radicals.

In 1930 he settled in Paris, where he worked at the Collège de France until his death.
