Editing Rosenbach Museum (section)

== History ==

The Rosenbach Museum was founded in 1954 from the personal collection of Dr. Abraham Simon Wolf Rosenbach (1876-1952) and his brother Philip (1863-1953). Dr. Rosenbach was the preeminent rare book dealer of his era, known for acquiring some of the most significant literary manuscripts in existence.

The museum occupies a 19th-century townhouse near Rittenhouse Square, where the Rosenbach brothers lived and conducted their rare book business. The building itself is part of the collection, preserved as an example of how a prosperous Philadelphia family lived in the early 20th century.

In 2013, the Rosenbach became affiliated with the Free Library of Philadelphia Foundation, uniting two of the world's preeminent collections of rare books and manuscripts.
