Bra - better than the steamboat, really - the Awesome World of Things
As a publishing luminary of the expatriate bohemian scene in late-'20s Paris, Caresse Crosby helped launch the careers of D.H. Lawrence, Ernest Hemingway and James Joyce. Years earlier, as a 19-year-old Manhattan socialite, she laid the groundwork for a fashion revolution when she and the family maid used two silk handkerchiefs, pink ribbon, and a cord to produce a forerunner to the modern bra. She patented her "backless brassiere" and then sold the patent to the Warner Bros. Corset Co. the following year for $1500. Writing later in life, she said: "I can't say the brassiere will ever take as great a place in history as the steamboat, but I did invent it." - Popular Mechanics.
