The only Quaker Study Centre in Europe, it was founded by
George Cadbury in 1903 and occupied one of his former properties on Bristol Road. Woodbrooke's first Director of Studies was the biblical scholar
J. Rendel Harris. Other early staff included
Horace Gundry Alexander and
Leyton Richards, a prominent pacifist who was appointed as Warden in 1916. The college was extended between 1907 and 1914 by the addition of a new wing, a new common room and Holland House, a men's
hostel. By 1922 it was estimated that 1,250 British students and 400 foreign students had attended the college. It was federated with eight other nearby colleges, including
Fircroft College,
Prospect Hall, and
Westhill College, known collectively as
Selly Oak Colleges until the federation ended with the closure of Westhill in 2001. ==Closure of conference centre==
