From Today in Science History:
In 1925, a meeting of local leaders was held in Dayton, Tennessee, to plan a challenge to that state’s new law, the Butler Act, which made it illegal to teach Darwin’s theory of evolution in a public school. George W. Rappelyea and other local leaders of the small mining town met at Robinson’s drug store. The American Civil Liberties Union in New York, concerned by the law’s infringement on constitutional rights, had advertised an offer to give legal support to any teacher who would challenge the law. Rappelyea saw the publicity that would accompany such a trial as an opportunity to promote his town. He approached John T. Scopes, a 24-year-old teacher and football coach, who was hesitant at first, to test the legality of the law in court.
