The Unpublishable Memoirs.

The Unpublishable Memoirs Was published in 1924 by A. S. W. Rosenbach. He was an avid American collector, scholar, and seller of rare books and manuscripts. Abraham was the youngest of the eight children of Morris Rosenbach (May 14, 1820 — May 8, 1885) and Isabella H. Polock (November 26, 1834 — July 25, 1906), who were married on November 11, 1857. As a child, Abraham spent much time in the shop of his maternal uncle, Moses Polock (May 14, 1817 — August 16, 1903), a well-known and somewhat eccentric antiquarian bookseller. Polock's famous shop was located at 406 Commerce Street in Philadelphia. Abraham got his start collecting while a freshman in college at the University of Pennsylvania. His company, simply called the Rosenbach Company, went on to help assemble the extensive collections of the Huntington Library and the Folger Shakespeare Library.
