Olds led the Council for Financial Aid to Education, an organization that directed corporation donations to universities. He spent two years as the President of the
New-York Historical Society, and was a benefactor and board member of both the
Metropolitan Museum of Art and
Lincoln Center for the Performing Arts. He studied naval history and had published two works, about the topic, "U.S. Naval History, 1776–1815" and "Bits and Pieces of American History". He collected
Revolutionary War and
War of 1812 Naval Prints, and had a collection of over 1,000 items, many of which were donated upon his death to White & Case and the New-York Historical Society. Olds's collection served as an inspiration to his wife, Evelyn Foster Olds. An amateur painter, she took the themes and images she found in Olds's prints and painted them on trays and other objects. In February 1957, Harry Shaw Newman organized an exhibition of her work at the Old Print Shop in New York. The following year, Evelyn's work was shown at the Peabody Museum and, in cooperation with the United States National Museum and the United States Marine Corps Museum, at the Smithsonian's Arts and Industries Building. Olds died on March 4, 1963, and was interred at
Woodlawn Cemetery, in
the Bronx. ==Legacy==
