Biography of El Dorado Jones
El Dorado Jones (1860-1932) ("Iron Woman") was an American woman inventor who is credited with inventing a light-weight electric iron, travel size iron board, and airplane mufflers in 1919. Jones had a factory in Illinois that employed only women past 40 that produced the products of her invention. She had a strong bias against men which hurt her in business. Because of this bias she was not able to capitalize on the report in the New York Times of successful test of her airplane muffler.
