Who did then?
Lewis Howard Latimer, who, like Garrett Augustus Morgan, inventor the modern Traffic Light, was wait for it... a Knee-Grow.
Latimer received a patent in January 1881 for the "Process of Manufacturing Carbons", an improved method for the production of carbon filaments used in lightbulbs.[6][7]
The Edison Electric Light Company in New York City hired Latimer in 1884, as a draftsman and an expert witness in patent litigation on electric lights. Latimer is credited with an improved process for creating a carbon filament at this time, which was an improvement on Thomas Edison's original paper filament, which would burn out quickly.[8]
