John T. Scopes (1900-1970), at the age of 24, was charged on May 25, 1925 with violating Tennessee's Butler Act, which prohibited the teaching of evolution in Tennessee schools.

In the so-called Scopes Monkey Trial, he was defended by Clarence Darrow and others from the ACLU, and prosecuted by William Jennings Bryan. The case ended with a guilty verdict, and Scopes was given a $100 fine, which was later overturned on a technicality. After the trial, Scopes was mainly employed by the oil industry, in both America and Venezuela.
