(l. to r.) 59 and 57 Fifth Avenue. Both were built as houses in 1852-53 by industrialist, philanthropist, and bibliophile James Lenox. For generations from the time it was built, No. 59 was home to a family that was among the most important American patrons of the arts of the 19th century, and included significant figures in the fields of science, philanthropy, business, and government. In later years it also housed a prominent publisher, bookseller, and artist studios. No. 57, altered to its current appearance in the early 20th century, was the home of congressman, conservationist, and Civil War Unionist Robert B. Roosevelt (uncle to Theodore Roosevelt), as well as the groundbreaking Pearson’s Magazine and bookstore.
