Peter Hamilton Raven FMLS (born June 13, 1936) is a botanist and environmentalist, notable as the longtime director, now President Emeritus, of the Missouri Botanical Garden. On June 13, 1936, Raven was born in Shanghai, China to American parents. An uncle of his father's was, for a time, one of the wealthiest Americans in China, but was later jailed in a banking scandal. That incident and Japanese aggression in China led the Raven family to return to San Francisco, CA in the late 1930s.After becoming a member of the California Academy of Sciences while still a youth, Raven went on to graduate with a BSc in Biology from the University of California, Berkeley in 1957 and a Ph.D. in botany from the University of California, Los Angeles in 1960.
