The Pennsylvania Historical and Museum Commission (PHMC) recently approved 37 new historical markers, making this one of the largest number of new markers in the program’s history.

Approval Criteria require that marker subjects have statewide and/or national and a substantial association with Pennsylvania. The Marker Program encourages broad distribution, so individuals and organizations from all 67 counties are encouraged to research their history and develop nominations for people, places, events, and innovations in their own area.

This year’s markers span a broad range of subjects, including art and music, literature, early American history, legal battles, industrial history, medical advancements, religious affiliations, social activism and civil rights, and sports legends.

New to the list of Pennsylvania Governors will be Richard L. Thornburgh (1932-2020), Rosslyn Farms Borough, Allegheny County.

Dick Thornburgh was the 41st Governor of Pennsylvania. As U.S. Attorney General, he played a leading role in the enactment of the Americans with Disability Act and the investigations in the Pan Am Flight 103 bombing, the Exxon Valdez oil spill, and Rodney King’s death. As Governor, he faced the nation’s worst nuclear accident (Three Mile Island) weeks after his inauguration in 1979.
