rates. Hetty then regularly commuted to her office in the Chemical Bank on Broadway. By 1905, Hetty was New York's largest lender. Unsubstantiated rumors claimed that she ate only oatmeal, eggs, and onions, unheated so as not to increase her fuel bill. In her old age, Green developed a hernia, but refused to have an operation, preferring to use a stick to press down the swelling. She eventually moved her office to the National Park Bank, when she thought she had been poisoned at the Chemical Bank, a fear she had most of her life. Death On July 3, 1916, Green died at age 81 at her son's New York City home. According to her longstanding "World's Greatest Miser" entry in the Guinness Book of World Records, she died of apoplexy after arguing with a maid over the virtues of skimmed milk. The New York Times reported she suffered a series of strokes leading up to her death. Upon her death, Green was known as the "Wizard of Finance" and the "Richest Woman in America." Estimates of her net worth ranged from $100 million to $200 million (equivalent to $ to $ in ), making her arguably the richest woman in the world at the time. Green was buried at the Immanuel Cemetery at the Immanuel Episcopal Church in Bellows Falls, Vermont, next to her husband. She had converted late in life to his Episcopalian faith so that she could be interred with him. Their two children split her estate, which included a ten-year trust for Sylvia administered by Ned. They were reported to have enjoyed their wealth more than she had. Both came through the Great Depression relatively unscathed by following Hetty's philosophy of conservative buying backed by substantial cash reserves. Ned was an accomplished collector with interests in everything from auto racing to science to horticulture. He willed his estate to his sister Sylvia, who in 1948 donated his Round Hill, Massachusetts, estate to the Massachusetts Institute of Technology (MIT), which used the property for experiments. These included a prototype particle accelerator. They used his powerful WMAF radio transmitters to keep in touch with Richard E. Byrd's 1928–1930 Antarctic expedition. Sylvia Green died in 1951, leaving an estimated $200 million and donating all but $1,388,000 to 64 colleges, churches, hospitals, and other charities. Both children were buried near their parents in Bellows Falls. Legacy The She-Wolf (1931) and
