Sylvester K. Stevens (1904-1974) was Pennsylvania State Historian and, from 1956 to 1972, executive director of the Pennsylvania Historical and Museum Commission. The author of many volumes on the Commonwealth’s history, his classic Pennsylvania: Birthplace of a Nation (1964) drew a famous court suit from the daughter of Henry Clay Frick, who charged that Stevens was too harsh on the industrialist; the court sustained Stevens’s judgment.
