Black Inventors You Should Know About
Lewis Latimer was the son of runaway slaves, and fought for the Union during the Civil War before being honorably discharged. He went on to patent a variety of inventions, including functioning bathrooms for railway cars and a locking coat rack. He was also integral in the patenting of the telephone and in the development the electric light, accomplishments that are all the more impressive given the prejudices of the time. In 1876, Alexander Graham Bell recruited him to draft the drawings of the telephone for its patent application. Latimer submitted them mere hours before another application for a similar invention by Elisha Gray. Later, Latimer took on the challenge of improving Edison's light bulb design, having been hired by Edison's rival Hiram Maxim. Edison's bulbs burned out within a few days due to the nature of their filaments. Latimer's filament design made the bulbs last much longer, reducing their cost and enabling electric lighting to become more commonplace. Edison later hired Latimer as a draftsman, engineer, and expert witness in patent litigation. Latimer would go on to become the only black member of the Edison Pioneers, a group of men credited with launching the electrical industry.
