He had successes and based his work on earlier designs.
He wasn't even the first person to 'invent' it, Humphry Davy had a working electric light in 1802, Warren de la Rue had a working, but expensive, filament bulb in 1840 and Joseph Swan beat Edison to the patent on an affordable bulb. Edison deserves credit for making electric lighting a practical and affordable option and was a driving force behind putting the necessary infrastructure in place, but he wasn't developing electric light bulbs as a visionary opposing popular opinion, it was an idea that's time had come and there was a race to perfect a product that had been in development for about 80 years. Lewis Hamilton Latimer made a cheaper and longer lasting bulb a couple of years later, but for some reason I can't fathom he never became a national hero...
