Christian Gottfried Ehrenberg was a German naturalist, zoologist, comparative anatomist, geologist and microscopist.
John Gould was an English ornithologist. He published a number of monographs on birds, illustrate by plates produced by his wife, Elizabeth Gould, and several other artists including Edward Lear, Henry Constantine Richter, Joseph Wolf and William Matthew Hart. His identification of the birds now nicknamed 'Darwin's finches' played a role in the inception of Darwin's theory of evolution by natural selection. Gould's work is referenced in Charles Darwin's book On the Origin of Species
