Richard Julius Petri

Born 31 May 1852; died 20 Dec 1921 at age 69.German physician and bacteriologist, remembered for his name given to the Petri dish. This is a shallow, cylindrical dish made of plastic or glass with a cover, used for tissue cultures and to hold solid media for culturing and sub-culturing bacteria.
