Samuel McPherson Janney was a Virginia Quaker minister, author, educator, and reformer. In 1839 he opened a boarding school for girls in Loudoun County. He traveled widely in the ministry, meeting with other denominations as well as being immersed in the contemporary issues facing the Society of Friends. Among his activities were establishing schools for African Americans and women, creating public schools in Virginia, and the abolition of slavery. In 1869 he was appointed Superintendent of Indian Affairs in Nebraska. The collection contains primarily correspondence of Samuel M.
