Erasmus Darwin (1731-1802)
Trained as a physician, he wrote extensively on medicine and botany. Living in Birmingham, England, he corresponded and discussed many topics with other members of the Lunar Society.
His long poem `Zoonomia' is widely considered to foreshadow the Theory of Evolution formulated by his grandson Charles Darwin. Another of his grandsons was Francis Galton. He was also a source for Mary Shelleys Frankenstein, because he was experimenting in galvinism.
