Swarthmore College is a private, independent, liberal arts college in the Swarthmore, Philadelphia. The school was founded in 1864 by a committee of Quakers who were members of the Philadelphia Yearly Meeting of the Religious Society of Friends. Swarthmore dropped its religious affiliation and became officially non-sectarian in the early 20th century. The college has been coeducational since its founding. "Swarthmore" can be pronounced with the first "r" either vocalized or dropped due to differences in rhotic and non-rhotic accents. Swarthmore's campus is home to the Scott Arboretum.
