The Schoolcraft home of Dr. Nathan Thomas served as a "station" on the Underground Railroad. Dr. Thomas, the first doctor in Kalamazoo County and a Quaker who avidly supported and led abolitionist efforts in Michigan, first built the house in 1835 on the corner of Cass St. and Centre St. Between 1840 and 1860, it is estimated that Dr. Thomas and his wife Pamela Brown Thomas sheltered between 1,000 and 1,500 fugitive slaves on their way to Canada. Dr. Thomas built a new house in 1868 and the original house was moved to its present site on Cass St. east of U.S. Route 131. The house is listed on the National Register of Historic Places and is a registered Michigan Historical Site.
