M. (Marcellin) Berthelot

Born in Paris in 1827, Marcellin Berthelot became one of France’s best-known chemists. He was especially noted for work in organic and synthetic chemistry, and his research helped challenge the old idea that organic compounds could only be produced by living things.

His interests reached well beyond the lab. He wrote extensively on the history of chemistry, ancient science, and alchemy, bringing scholarly attention to subjects that many scientists had ignored. That mix of experiment and historical curiosity made him an unusually broad intellectual figure.

Berthelot was also active in public service, including work in the French Senate and a period as foreign minister. He died in 1907, and he remains remembered as both a major scientist and an influential public thinker of his era.
