chimp boy

Ok perhaps the title should be chimp AND boy - but a chimp boy is a little more exciting.
In the early 1930's the Kellogg's, after seeing feral children, decided that they wanted to see what the influence of environment had on the development on humans.

One way to test this hypothesis would be to place a human infant of normal intelligence in an uncivilized environment and to observe systematically its 'development' in that environment. Kellogg noted that while such an experiment would be both morally outrageous and illegal, there was another way, albeit somewhat indirect, to test the environment-heredity question. That was to take a wild animal and place it in the civilized environment of a human home (Kellogg & Kellogg, 1933). Thus began the attempt to produce this unusual experiment. (B&B p. 466)
