The John Findley Green Foundation lecture was established in 1936 as a memorial to John Findley Green, an attorney in St. Louis who graduated from Westminster in 1884. The foundation provides for lectures designed to promote understanding of economic and social problems of international concern. It further provides that "the speaker shall be a person of international reputation." Former British Prime Minister Winston S. Churchill delivered the John Findley Green Lecture on March 5, 1946.
The Enid and R. Crosby Kemper Lectureship was established in 1979 by a grant from the Enid and R. Crosby Kemper Foundation of Kansas City, Missouri. It is intended to provide for lectures by authorities on British History or Sir Winston Churchill at the National Churchill Museum. The established Lectureship is held under the auspices of the British Institute of the United States and the National Churchill Museum.
