Andrew Philip Kehoe (February 1, 1872 – May 18, 1927) was an American farmer and treasurer of his township school board, notable as a mass murderer for killing his wife, and 43 other people (including 38 children), and injuring 58 people by setting off bombs in the Bath School Disaster on May 18, 1927. He committed suicide near the school by detonating dynamite in his truck, causing an explosion which killed several other people and wounded more. He had earlier set off incendiary devices in his house and farm, destroying all the buildings, as well as two horses and other animals.
