Seymour LeGrand Cromwell (April 24, 1871 – September 16, 1925)[1] was an American banker who served as president of the New York Stock Exchange.
During World War I, twins Dorothea and Gladys volunteered with the Red Cross and, reportedly due to the strain of the hospital work, the 22 year-olds committed suicide in January 1919 by jumping from the deck of the French passenger ship La Lorraine as the steamer was in the Garonne river and they were on their way home to New York.
[1] In 1925, Cromwell advanced the idea that Wall Street was "making 'vital efforts to realize in fact many of the aims so much talked about during the war, and the economic and social ideals urged by the liberals.
'"[10] After his retirement from the presidency of the Exchange,[11] he focused on his own business as a partner in the firm of Strong, Sturgis & Co., with offices as 11 Wall Street.
[28] In 1927, his widow sold their New Jersey estate to the Sisters of Christian Charity (as a retreat and guest house)[28] for $50,000,[29] and later moved to 993 Park Avenue.
[35] Through his eldest son, he was a grandfather of champion oarsman Seymour Legrand Cromwell II (1934–1977), a Princeton graduate and naval architect who helped the United States win a silver medal in the 1964 Olympics in Tokyo.
