From 2011 – 2016 Harry was Director of the Museum at the Pennsylvania Academy of the Fine Arts, known internationally for its collections of 19th- and 20th-century American art.  He spearheaded a revived engagement with contemporary art at PAFA, including PAFA's first large-scale gallery intervention exhibition, KAWS @ PAFA, which featured over 60 KAWS paintings and sculptures — many of them newly created for the exhibition — in the galleries and on the façade of the Historic Landmark Building, and the installation of the sixteen-feet-tall Companion (Passing Through) sculpture in Philadelphia’s 30th Street Station.

He led the effort to create, through a carefully planned and executed deaccessioning, a $35m collections endowment.  This endowment rekindled the Museum’s program of actively collecting contemporary art, with an emphasis on female and African American artists which was celebrated by Artnet News as “a case study for how such moves can create permanent and profound change within an institution.”
