Thomas Shipley Brown (1912-2011) of Cheltenham Pennsylvania, was an active member of the Religious Society of Friends (Quakers) who wrote and taught widely about Quaker thought, life, and practices. He graduated from Westtown School, a prominent Quaker boarding school (West Chester, Pa.) in 1929 and taught Bible, Latin, and English there for much of his life. He was involved with a number of other Quaker organizations including Philadelphia Yearly Meeting, Friends Council on Education, the American Friends Service Committee, and London Yearly Meeting. The Thomas Shipley Brown papers, 1920-2011, is largely made up of Thomas Shipley Brown's writings on Quakerism and materials from his involvement with several Quaker organizations, especially Quaker educational institutions (including Westtown).
