Darwin, Erasmus, 1731–1802, English physician and poet. During most of his life he practiced medicine in Lichfield and cultivated a botanical garden. He was a prominent member of the Lichfield literary group, which included Anna Seward and Thomas Day. In a long poem, The Botanic Garden (1789–91), Darwin expounded the botanical system of Linnaeus. His Zoonomia (1794–96), explaining organic life according to evolutionary principles, anticipates later theories. He was the grandfather of Charles Darwin and of Francis Galton.
