Lewis Latimer

Born 4 Sep 1848; died 11 Dec 1928 at age 80. Lewis Howard Latimer was a Black-American inventor who contributed to electrical technology. After joining a Boston firm of patent solicitors as an office boy, he taught himself drafting and eventually rose in the mid-1870's to the position of chief draftman. Meanwhile, he was issued his first patent for his invention of a water-closet for railroad cars. In 1880, he moved to be draftsman and private secretary to Hiram Stevens Maxim of the U.S. Lighting Co. where he took charge of the installation of commercial incandescent lighting systems. He patented his carbon filament lamp improvements and other inventions. By 1883, he was working for the Edison Electric Light Co., where his expertise with patents was recognised with a position with its new legal department in 1889.«
