Known as the Scopes Monkey Trial, The State of Tennessee v. John Thomas Scopes was held in Dayton, Tennessee in 1925. The State of Tennessee accused John Scopes, a high school substitute teacher, of violating the Butler Act, which made it unlawful to teach human evolution in publi schools in the state. The trial drew intense national publicity with famous legal representation for the prosection and the defendant in William Jennings Bryan and Clarence Darrow. Although Scopes was found guilty and fined 100 dollars, the verdict was overturned on a technicality. The trial's impact is evident in biology textbooks from the 1920s and 1930s which graduallly incorporated more details about human evolution. Robert D. MacMurdy, Head of the Department of Education at Centenary College in the 1960s, collected newspaper clippings, printed ephemera, and postcards related to the famous trial.
