In October 1879 Thomas Edison managed to make a light bulb that burned for 13.5 hours. Later he made one that lasted over 100 hours, and finally one that would burn for more than 1200 hours. He got a patent for this in 1880.
Thomas invented the phonograph in the year of 1878 and took him 30 hours with a little help from his Friend john kruesi.Edison is credited with the invention of the phonographin 1877.thomas Edison invented the phonograph in the year 1877. he demonstrated the phonograph on Dec.7th 1877 at the office of SCIENTIFIC AMERICAN.
Thomas Edison crowns 14 months of testing with an incandescent electric light bulb that lasts 13Â½ hours
Edison did not invent the lightbulb. He purchased the 1875 patent he purchased from inventors, Henry Woodwardand Matthew Evans and improved on it. His contribution was to develop a carbon filament that burned for forty hours. Edison placed his filament in an oxygenless bulb.

Thomas Edison invented the electric light bulb. The first successful test of his invention was in October of 1879, during which the light lasted for over 13 hours. He acquired the patent in 1880.
The history of the Incandescent light bulb begins long before Edison, and his light bulb was NOT the original invention of the light bulb. In 1809 an English chemist named Humphry Davy invented the first electric light. A series of men followed, each creating their own version, and submitting patents. At the same time, Edison was working independently and eventually bought the patent rights from two of the other inventors. Then, in 1879, Thomas Alva Edison invented a carbon filament. It burned for forty hours, and this prototype would go on to become today's "light bulb".October 22, 1879
Thomas A. Edison could not have worked the incredibly long hours (sometimes up to 72 hours to complete a project) drinking any depressant, such as alcohol. He was driven by success. He smoked cigars, but these produced meditative thoughts that fueled his creativity.
