Snodgrass) (July 5, 1875 – September 4, 1962) was an American entomologist and artist who made important contributions to the fields of arthropod morphology, anatomy, evolution, and metamorphosis.

His admitted first ambition in life was to be a railway engineer or a Pullman conductor, though frequent visits to the St. Louis Zoo aroused his early interests in zoology.

[1] He studied Latin, Greek, French, German, physics, chemistry, and drawing, but notably no biology because the curriculum forbade involving the teaching of evolution.

[1] Snodgrass bypassed this problem by reading the English scientists Charles Darwin, Thomas Henry Huxley and Herbert Spencer in his free time.

[1] His openly professed belief in evolution caused him problems in his relationships at home, and eventually resulted in being expelled from church activities in his community.
