A minister and a missionary founded Oberlin in 1833. Reverent.  John Shipherd (minister) and Philo P. Stewart (missionary), became  friends while spending the summer of 1832 together in nearby Elyria. They  discovered a mutual disenchantment with what they saw as the lack of strong  Christian principles among the settlers of the American West. They decided to  establish a college and a colony based on their religious beliefs, "where they would train teachers and other Christian leaders for the  boundless most desolate fields in the West".[2]
