The Story

Founded in 1824 by prominent Philadelphians, the Historical Society of Pennsylvania is among the oldest institutions of its kind in the nation and has occupied this site since 1884. Its special collections hold many of the country's foundational documents, chronicling American life from the seventeenth century onward. The Society emerged in the Early Republic's surge of civic and antiquarian energy, as a young nation set out to preserve its own record.

Why it matters

As one of America's earliest historical societies, it helped pioneer the very idea of systematically preserving the nation's documentary heritage.

New Century Guild

Philadelphia, PA · est. 1997

Founded in 1882 by Eliza S. Turner, the New Century Guild became one of the oldest and largest organizations devoted to improving the lives of women in the paid workforce.

Philadelphia Sketch Club

Philadelphia, PA · est. 2008

Founded in 1860, the Philadelphia Sketch Club is the oldest artists' club in America, started by illustrators who discovered that gathering together to draw and talk sharpened both their skill and their eye. Over the decades its rolls read like a roster of American art, counting Thomas Eakins, Thomas Anshutz, and members of the Wyeth circle among its ranks. The club made social fellowship a working part of the creative life.

Louis I. Kahn (1901-1974)

Philadelphia, PA · est. 2004

Louis I. Kahn ranks among the most influential architects of the postwar era, a designer who treated mass, light, and structure as the very substance of his buildings. Trained in the Beaux-Arts tradition at the University of Pennsylvania, he later taught there and ran his practice from this location, producing monumental works admired around the world. His buildings are known for their weighty, almost ancient presence married to a modern sense of purpose.

Medical Library Association

Philadelphia, PA · est. 2015

In 1898, at the close of a century that had transformed medicine into a science, a small group of American and Canadian physicians and librarians met in Philadelphia to solve a stubborn problem: doctors could not easily reach the reliable, up-to-date medical literature their patients' lives depended on. Their answer was the Medical Library Association, the world's oldest body of its kind, dedicated to organizing and sharing trustworthy medical knowledge. Among its founders stood the celebrated physician Sir William Osler and the librarian Margaret R. Charlton, pairing clinical prestige with the emerging profession of medical librarianship.
