Joseph Clifton Trees was a college football player at the University of Pittsburgh, the first athlete to receive an athletic subsidization at the school, and, possibly, an early professional football player. He later made millions of dollars in the oil industry and became a trustee and significant benefactor to the university and its athletic department. His hobbies included philanthropy, scientific research and agriculture. His 2,600-acre (11 km2) estate in Gibsonia, Pennsylvania was devoted to a large extent to fruit trees.
