William L. Harkness
William Lamon Harkness (August 8, 1858 – May 10, 1919) was an American businessman and inheritor of a large share of Standard Oil. Early life
William Lamon Harkness was born in Bellevue, Ohio, the son of Daniel M. Harkness, who was the half-brother of both Henry Flagler and Stephen V. Harkness, both founders of Standard Oil, and his wife Isabella Harkness. Upon his father Daniel's death in 1896, he inherited a large share in Standard Oil, a company in which his father had been an early shareholder. He is also a cousin of noted philanthropist Edward Harkness who also benefitted from his father's involvement with Standard Oil. He attended Bellevue Public Schools in Bellevue, Ohio and The Brooks Military School in Cleveland. In 1881, Harkness graduated from Yale University. Life
In 1896, he moved from Cleveland, Ohio to a home at 12 East 53rd Street in New York City. He also owned a country home, Dosoris, at Glen Cove on Long Island. A yachtsman and sportsman, he was a member of The Union Club of Cleveland, The Metropolitan Club New York, New York Yacht Club, the Seawanhaka Corinthian Yacht Club and Piping Rock Club. In August 1911, while in command of his steam yacht Gunilda on Lake Superior, he ran her aground, due to his failure in recognising a requirement for a pilot and then compounding the matter by not hiring tugs at the appropriate time. She would sink in days. He put in a claim against the ship's insurer, Lloyd's of London for about $132,000 dollars, and received $100,000 compensation. Philanthropy

Shortly before his death, Harkness donated $400,000 to Yale University. The William L. Harkness Hall at Yale University was completed in 1927 as the gift of Mr. W.L.
