Physician, botanist, poet, and grandfather of Charles Darwin. Containing a nascent theory of evolution, The Loves of Plants (1789) was later incorporated into The Botanic Garden (1791). In depicting plant reproduction and generation, Darwin's imagery sometimes becomes so erotic that some conservative authorities on education recommended denying young ladies access to his work. In addition to his two other major pieces, Zoonomia (1794) and The Temple of Nature (1803), he published additional works on botany as well as commemorative poetry and treatises on scientific topics and female education.
