William Seward Webb (January 31, 1851 – October 29, 1926) was a businessman, and Inspector General of the Vermont militia with the rank of Colonel. He was a founder and former President of the Sons of the American Revolution. William Seward Webb was born on January 31, 1851 to James Watson Webb. He studied medicine in Vienna, Paris and Berlin. Returning to America, he entered the Columbia University College of Physicians and Surgeons and was graduated from there in 1875. For several years he practiced medicine, and then forsook the profession for finance at the behest of his wife’s family, establishing the Wall Street firm of W. S. Webb & Co. In 1883, he married Eliza Osgood Vanderbilt, daughter of William H. Vanderbilt. Eliza’s brother George went on to create the Biltmore Estate, one of America’s grandest country estates. In 1883, Webster Wagner, the president of the Wagner Palace Car Company, was crushed between two of his own railroad cars. Vanderbilt owned a controlling interest in the company, and asked his new son-in-law to take over the firm. William Seward invited his brother H. Walter Webb to join him, which started them both on careers in the railroad business. The Wagner Palace Car Company was subsequently merged with the Pullman Company. Dr. Webb later became President of the Fulton Chain Railway Company, the Fulton Navigation Company, and the Raquette Lake Transportation Company. He was the builder and President of the Mohawk and Malone Railway. His railroads were instrumental in opening the Adirondacks to the tourism rush of the mid- to late 19th century. Dr. Webb served as Inspector General of the Vermont militia with the rank of Colonel. He served a term in the Vermont Legislature in the 1890s. William Seward Webb died on October 29, 1926 and was survived by his wife, Lila Vanderbilt Webb, three sons – J. Watson, William Seward, and Vanderbilt – and one daughter, Frederica.
