The Story

In the early 20th century, A. S. W. Rosenbach reigned as the most famous rare-book and manuscript dealer in America, the man great collectors and libraries turned to when they wanted a Shakespeare folio or a founding-era document. With his brother Philip he assembled a personal treasure trove and then gave it a permanent public home as the Rosenbach Museum & Library. The brothers lived on this Philadelphia block for the last quarter century of their lives.

Why it matters

Rosenbach helped stock many of the nation's greatest libraries, ensuring that priceless works of literature and history stayed in America and reached the public rather than vanishing into private vaults.

Edward Drinker Cope

Philadelphia, PA · est. 2002

The paleontologist and zoologist Edward Drinker Cope lived and worked in this Philadelphia neighborhood in his later years, producing a torrent of scientific papers that described hundreds of fossil and living species. He is best remembered for the "Bone Wars," his fierce, decades-long rivalry with Othniel Charles Marsh of Yale to unearth and name new dinosaurs. Their competition, however bitter, dramatically expanded American knowledge of prehistoric life.

Vincent Persichetti (1915-1987)

Philadelphia, PA · est. 1997

Philadelphia-born Vincent Persichetti became one of his city's most respected twentieth-century composers, producing nine symphonies alongside a vast body of instrumental and choral music. A 1939 graduate of the Curtis Institute, he shaped generations of musicians as a teacher at the Philadelphia Conservatory and, for four decades, at the Juilliard School. His work bridged accessible melody and modern technique.

Mercy Hospital

Philadelphia, PA · est. 1992

Founded in 1907 by African Americans, Mercy Hospital gave Black doctors and nurses a place to train and practice at a time when other Philadelphia hospitals excluded them. It grew quickly, building a larger facility here in 1919 to meet the community's needs. In 1948 it merged with the Frederick Douglass Memorial Hospital to form Mercy-Douglass Hospital.

Frederick Douglass Memorial Hospital

Philadelphia, PA · est. 1992

When it opened in 1895, Frederick Douglass Memorial Hospital became Philadelphia's first hospital serving the Black community, at a time when segregation shut Black doctors and nurses out of most medical institutions. It offered both care to patients and training and employment to Black medical professionals who were otherwise barred from practice. In 1948 it joined with another Black-founded institution to form Mercy-Douglass Hospital.
