Frederick M. Jones held more than 60 patents during his life, with most of them pertaining to refrigeration. His portable refrigeration technology was used in World War II to preserve food and blood serum.
Madame C.J. Walker, born Sarah Breedlove, created specialized hair products for African-American hair and became the first American woman to become a millionaire through her own business.
History has credited Thomas Edison with the invention of the light bulb, but fewer people know about Lewis Howard Latimer's innovationstoward its development. Edison's light bulbs only burned for a short time until Latimer's carbon filaments were utilized, significantly lengthening bulb life.
Joseph Lee received a patent for his bread-crumbing machine in 1895 and patented a bread-making machine in 1902. His inventions revolutionized the industry.
In 1897, John Lee Love received a patent for his portable pencil sharpener, dubbed the "Love Sharpener."
Thomas J. Martin patented improved fire extinguishing technology in 1872.
Jan Ernst Matzeliger, of Surinamese and Dutch descent, invented the shoe-lasting machine, which connected the upper part of the shoe to the sole. His device, patented in 1883, greatly increased shoe productivity and made footwear more affordable.
Canadian engineer Elijah McCoy invented an automatic lubricator for oiling steam engines, for which he received his first patent in 1872. He would earn dozens of patents over his lifetime, and the term "the real McCoy" is believed to have referred to the reliability of his devices.
Alexander Miles patented an improved elevator system in 1887. His system included automatic doors that would close off the shaft way, thus making elevators safer.
In 1914, inventor Garrett Morgan patented a breathing device in the form of a canvas hood - a precursor to the modern gas mask. He later became renowned for using his device to save workers who were trapped in a toxic fume-filled tunnel.
Garrett Augustus Morgan invented, among many other things, the first automatic three-way traffic signal system, which he eventually sold to General Electric.
In 1897, Lloyd P. Ray received a patent for an improved type of dustpan.
George T. Sampson earned a patent in 1892 for inventing a clothes dryer that used heat from a stove.
Lewis Temple revolutionized the whaling industry with his invention of the toggle harpoon in 1848.
James West's research in sound technology led to the development of foil-electret transducers, with the innovation used in 90 percent of contemporary microphones. West holds more than 250 patents and was inducted into the National Inventor's Hall of Fame in 1999.
In 1878, Virginia native Joseph Winters patented a folding escape ladder mounted on fire wagons.
Granville Woods invented a number of devices related to railroad engineering, including air brake systems and what would become known as the "third rail" on modern tracks. He was also a pioneer in telegraph and telephone technologies, and would earn dozens of patents over his lifetime.
