Boone was born on a North Carolina plantation. In 1847, she married James Boone, a free man who likely bought her freedom. By 1856, they moved to New Haven, Conn., which was a hub of industry from carriages to clocks. New Haven was also the epicenter of the corset industry, producing nearly 70 percent of the world’s supply. Boone was a dressmaker who decided to come up with a better way to iron these tight fitted dresses. She received U.S. Patent 473,653 on April 26, 1892 for an ironing board.
