Gov. Tom Corbett will unveil a portrait of Philadelphia and Pennsylvania founder William Penn's second wife in Harrisburg on Wednesday.
Hannah Callowhill Penn, who was three decades younger than the revered Quaker, is well known for running the Commonwealth in the 18th century after Penn suffered a series of strokes.
Hannah, who lived about 20 miles from the city for a majority of her marriage, took full control of the colony — managing all of the financial and legal affairs — for six years after Penn's death in 1718.
Hannah Callowhill Penn died from a stroke five days before Christmas in 1726, and the governance of Pennsylvania transferred to their three sons: John, Thomas and Richard, according to Historic Philadelphia.
The portrait, which will be placed in the Governor’s Office, will be unveiled at 10 a.m. in the Governor’s Reception Room at the State Capitol.
