PHILADELPHIA (CBS) – A new exhibit at the Historical Society of Pennsylvania looks at the life and work of Philadelphia mayor Richardson Dilworth.

Curator Jacqueline DeGroff shows off the many photos of Richardson Dilworth who, among a great number of other things, was mayor of Philadelphia from 1956 to 1962.

“He made many contributions to the city. He was the first to really work on segregation in the private schools. He instituted the One Percent Art program where if you build a building, you had to devote at least one percent to art.”

The photos are from the law firm Dilworth founded – Dilworth Paxson – while several cases show off letters and other important papers from the Dilworth Collection.

The Historical Society is preserving 251 boxes of documents from that collection. The exhibit will be at the Society at 13th and Locust through July 15th.
