Keeping It Real: In 1897, African-American inventor Alfred Cralle patented the first ice cream scoop. His original design remains in wide use, even today.
George T. Sampson invented a clothes dryer that used heat from a stove in 1892.
Nathaniel Alexander was the first to patent the folding chair. His invention was designed to be used in schools, churches and at large social gatherings.
George Carruthers invented the far ultraviolet electrographic camera, used in the 1972 Apollo 16 mission. This invention revealed new features in Earth's far-outer atmosphere and deep-space objects from the perspective of the lunar surface. Carruthers was inducted into the National Inventor's Hall of Fame in 2003.
African-American inventor Garrett Augustus Morgan created the gas mask—then became renowned for using his mask to save workers trapped in a toxic fume-filled tunnel. He also invented, among many other things, a three-way automatic stop sign, which he sold to General Electric. It was used in the U.S. until the three-light traffic sign was developed.
