Oris Paxton Van Sweringen (April 24, 1879 – November 22, 1936) and Mantis James Van Sweringen (July 8, 1881 – December 12, 1935) were brothers who became railroad barons in order to develop Shaker Heights, Ohio. They are better known as O. P. Van Sweringen and M. J. Van Sweringen, or by their collective nickname, the Vans. The brothers came from a farming area near Wooster, Ohio. Their father was for a time an engineer in the oil fields of Pennsylvania, fought in the Civil War and was wounded at the Battle of Gettysburg. The family moved to Cleveland, Ohio, in about 1890.
