Jack Morgan continued to live at 231 Madison Avenue until his death in 1943; his wife had died in 1925. Subsequently, the United Lutheran Church in America bought that house for its headquarters, and built a five-story annex in 1957. Next door, the Pierpont Morgan Library continued to expand its collections. The Fellows of The Pierpont Morgan Library was formed in 1949 to raise funds for the collections and distribute funds to scholars and publications. In the following decade, the Pierpont Morgan Library started to host concerts and tours. In 1960, the main library and its annex were connected by a cloister structure. The renovation, designed by J. P. Morgan's nephew Alexander P. Morgan, was completed in 1962 and included office space, a gallery, and meeting space.
