There are many known portraits of Charles Darwin. Darwin came from a wealthy family and became a well-known naturalist and author, and portraits were made of him in childhood, adulthood and old age. Darwin's life (1809–1882) spanned the development of photography, and early portraits of Darwin are drawn or painted, while many later portraits are monochrome photographs. After the publication and dissemination of the controversial On the Origin of Species in 1859, Darwin was also the subject of numerous caricatures.
