New Historical Markers Approved for 2015

The Pennsylvania Historical and Museum Commission (PHMC) approved 22 new historical markers at its March 4, 2015 meeting.  There are currently more than 2,000 PHMC markers throughout Pennsylvania and the program is one of the most popular and visible aspects of the Commission’s work.  The Commission has standard approval criteria that, among other things, require marker subjects be of statewide and/or national historical significance.  The majority of the newly approved markers are in Philadelphia (9), which is also where the most (20) nominations came from.  With such a long and rich history, it is no surprise that Philadelphia has the largest number of markers of any county in the state (over 250). The Marker Program encourages broad distribution, so individuals and organizations from the other 66 counties are encouraged to research their history and develop nominations for people, places, events, and innovations with statewide and/or national historical significance in their own area.

Newly approved markers in Philadelphia this year are:

  • Anthony Benezet, a Quaker abolitionist who was a pioneer in the education of females and African-Americans;
  • Dr. Constantine Hering, a pioneer in the field of homeopathic medicine whose research, discoveries, and educational methods transformed modern medicine;
  • Maxfield Parrish, nationally recognized artist and illustrator known for painting in vibrant shades of blue and capturing the spontaneity of movement.
  • Medical Library Association, the oldest medical library association in the world, founded to facilitate the accessibility of medical literature to medical practitioners, researchers, educators and students;
  • Sarah Josepha Hale

    Exciting to see the apriciation for our rich history so future generations will be able to lean from it.
    Quick question: Does anyone know if Lincrusta wallcovering was in any of these properties?

    I don’t see the mention of the marker for Governor Anthony Palmer, to be dedicated in October in Philadelphia, at the Palmer Cemetery. Palmer was the founder of KENSINGTON, and member of the Provincial Council for over 40 years. As senior member of council, Palmer became acting Governor from June, 1747 to December, 1748. Palmer died in May, 1749 and is buried at Christ Church Burial Ground.

    The Anthony Palmer marker was actually approved in September, 2014, mid-cycle. You are correct that the marker will be installed and dedicated on Saturday, October 17 in Philadelphia. Thank you for your interest in the PHMC Historical Marker Program.

      Thank You…Looking forward to the dedication…long overdue. Jim Kingsmill, Trustee, Palmer Cemetery
