Helen Miller Gould Shepard spent more money on
philanthropy than any other American woman of her time. At the commencement of the
Spanish–American War, she donated
US$100,000 to the United States government in support of the war. She gave an additional
US$50,000 toward military hospital supplies and was active in the
Women's National War Relief Association, working in a hospital for wounded soldiers in New York City and hosting convalescing soldiers on her Lyndhurst estate. Her war effort earned her the sobriquet "America's Sweetheart" and praise from the U.S. House of Representatives in the form of a Congressional bill passed in February 1899. and endowed its
Hall of Fame. It was the first of her many donations to her
alma mater. She made significant contributions to other educational institutions, from
Rutgers College in New Jersey to
American Robert College of Istanbul in Turkey, as well as to the
American Red Cross, the
Daughters of the American Revolution, and other organizations. She was a member of the board of the
Russell Sage Foundation and of the national board of the YWCA.
Olivia Sage, a leading advocate for women's education, was her close personal friend and mentor. On the witness stand during an eleven-year legal dispute among Jay Gould's heirs, she was asked how much money she had given away, to which she replied: "I do not know how much money I gave away, but I think I gave away most of it." Even so,
The New York Times would state in her obituary that "by judicious investment, she trebled her inheritance before resigning as a trustee of the Gould estate in 1927." For information on her charitable work at the Lyndhurst estate, see
