Impact on the world
His durable, longer-lasting carbon filament made incandescent lighting more practical and affordable, accelerating the spread of electric lighting. He also co-patented a mechanical railway car toilet with a closed-bottom design in 1874, addressing passenger sanitation on moving trains, well before his later, more famous work on lighting and telephone technology.
Life & background
A draftsman and inventor, Latimer drafted the patent drawings for Alexander Graham Bell's telephone and later developed an improved, longer-lasting carbon filament for incandescent light bulbs while working for Thomas Edison's company.
