The Historical Society of Pennsylvania (HSP) is now on the radio—with a biweekly broadcast on WHYY-FM that looks at current events through the lens of history. The segment is called That’s History and features Jonathan Zimmerman, an historian at HSP.

That’s History is produced in partnership with WHYY. The segment airs on 90.9 FM in the Delaware Valley every other Tuesday between 6 and 6:30 p.m. as part of the NewsWorks Tonight radio show. During each broadcast, Zimmerman and Chris Satullo, WHYY’s executive director of news and civic dialogue, take an event, issue or person in the news, and look back into history for echoes, parallels, roots, and lessons. A longer version of their conversation is posted online at NewsWorks.org. Visit HSP’s website at www.hsp.org to view documents, images, and articles that relate to each topic.

In addition to working as an historian at HSP, Zimmerman is a professor of Education and History at New York University. He is a former Peace Corps volunteer, high school teacher, and author. He is also a frequent op-ed contributor to the New York Times, the Philadelphia Inquirer, and other popular newspapers and magazines. Zimmerman, who lives in Narberth, is a Distinguished Lecturer for the Organization of American Historians and a Commonwealth Speaker for the Pennsylvania Humanities Council.
