Morgan Library & Museum, museum and library located in New York City that displays and collects artistic, literary, and musical works from ancient times to the present day. American financier and industrial organizer John Pierpont Morgan, who was also a collector of art, books, and other historic documents, commissioned the Morgan Library, designed by architect Charles F. McKim as an Italian Renaissance-style palazzo, to house his collection. The library, built from 1902 to 1906, was originally founded as a private institution, but in 1924 Morgan’s son, J.P. Morgan, Jr., opened the collection to the public as a gift and memorial
