Sarah Boone (1832 – 1904) was an African-American inventor. On April 26, 1892, she obtained United States patent number 473,563 for her improvements to the ironing board. Boone's ironing board was designed to improve the quality of ironing the sleeves and bodies of women's garments. The ironing board was very narrow, curved, and made of wood. The shape and structure allowed it to fit a sleeve and it was reversible, so one could iron both sides of the sleeve. Boone is regarded as the second African-American woman to attain a patent, after Judy Reed. Along with Miriam Benjamin, Ellen Eglin, and Sarah Goode, Boone was a pioneering African-American woman inventor who developed new technology for the home.
