Rosenbach Museum and Library

The Rosenbach is a Philadelphia museum and library located within two 19th-century townhouses. Established as a testamentary gift in 1954. The historic houses contain the donated collections of Philip Rosenbach and his younger brother Dr. Abraham Simon Wolf Rosenbach.

The brothers owned the Rosenbach Company, which was a prominent dealer of rare books, manuscripts and decorative arts during the first half of the 20th century. Dr. Rosenbach in particular was seminal in the rare book world, helping to build libraries such as the Widener Library at Harvard, The Huntington Library and the Folger Shakespeare Library. In 2013, the Rosenbach became a subsidiary of the Free Library of Philadelphia Foundation, but maintains its own board and operates independently of the public library system. Provided by Wikipedia
