Erasmus Darwin (1731–1802), was an English physician, natural philosopher, physiologist, inventor and poet. He was one of the founder members of the Lunar Society, a discussion group of pioneering industrialists and natural philosophers. His more famous grandsons were Charles Darwin and Francis Galton, though the latter may or may not be more infamous. He developed a theory of evolution,[notes 1] which, though similar to Lamarckism,[notes 2] probably inspired Charles's thoughts on the subject. His first name, Erasmus, is after the Dutch Humanist philosopher of that name.
