HSP Receives State Historical Marker

Tuesday, October 19, 2010

This year the Historical Society of Pennsylvania celebrates the 100th anniversary of its stately red brick building at the corner of 13th and Locust Streets. Thousands of people pass by this building every day, but few know the fascinating story behind this historic structure—one of the first fireproof libraries in the United States.

As part of the Society's year-long anniversary celebration, HSP will erect a blue-and-gold historical marker in front of its building at 1300 Locust Street. The unveiling ceremony will be held at 10 a.m. Monday October 25. All members and friends of the Society are welcome to attend. To RSVP, contact Emilie Kretschmar at ekretschmar@hsp.org or 215-732-6200 ext. 300. The brief ceremony will be followed by a reception and a display of original documents.

The building is 100 years old, but the Historical Society of Pennsylvania is much older. The Society was founded in 1824, and it moved several times in its early years. In 1883, the Historical Society finally purchased property at the corner of 13th and Locust, a mansion that had been constructed by John Hare Powel. The mansion was the former home of General Robert Patterson, who had served in the War of 1812, the Mexican War, and the Civil War. The house, with its gardens and greenhouses, was well known in Philadelphia, as Patterson had frequently entertained notable guests including author Charles Dickens and actress Fanny Kemble.

The Society members worried about the potential of fire to destroy or damage the Society’s historic collection, so they embarked on an ambitious building project on the site. Architect Addison Hutton drew up the plans for the renovations, and the building was ingeniously designed to be as fireproof as possible. Its thick walls are made of brick. No wood was used in the construction, not even for the bookcases or furniture. Each room was divided by a fireproof door hung on an inclined railway track, counter-weighted so that when the temperature rises a fusible plug melts and the door automatically closes.

In April 1910, construction was complete and the building opened to the public with much fanfare and two days of celebration. On April 7, a distinguished group of historians, scholars, Society members, and esteemed guests gathered in the Society’s Assembly Hall for a formal banquet. To celebrate the building’s 100th anniversary, the Historical Society invites the public to attend several special events in April, including behind-the-scenes tours. HSP will also display old photographs, documents, and architectural drawings on site.

Today the Historical Society of Pennsylvania is home to more than 21 million historic documents, graphics, and manuscripts. It is one of the oldest historical societies and one of the largest family history libraries in the nation. Following a merger with the Balch Institute for Ethnic Studies, HSP is also a leading repository of immigrant and ethnic history. We are second only to the Library of Congress for material on the nation’s founding and have one of the country’s most comprehensive collections for genealogical study.

“One hundred years have passed since that grand opening in 1910, and the Historical Society of Pennsylvania is still proud to call 1300 Locust Street home,” said HSP President Kim Sajet. “In the following years, we will continue to improve our building to better protect and share our nationally-significant collections and serve new and expanding audiences through the Internet, digital history projects, and e-publications. We look forward to another 100 years of inspiring people to create a better future through historical understanding.
