Chairman of the Vigilance Committee (part of the Pennsylvania Abolition Society), William Still assisted fugitive slaves as they were secretly shuttled into Philadelphia in the mid-1800s. From 1852 to 1857, Still kept a journal describing his encounters with the slaves in painstaking detail, recording their names, physical characteristics, personalities, and other details. Still's meticulous entries offer unique insight into the secretive network known as the Underground Railroad. The journal, which is owned by the Pennsylvania Abolition Society, was deposited at the Historical Society of Pennsylvania in the 1920s. Conservation and digitization of the journal was made possible in 2009 through a generous donation from the Penn Towne Chapter of The Links, Inc.
