Thomas Edison used this carbon-filament bulb in the first public demonstration of his most famous invention, the first practical electric incandescent lamp, which took place at his Menlo Park, New Jersey, laboratory on New Year's Eve, 1879.
As the quintessential American inventor-hero, Edison personified the ideal of the hardworking self-made man. He received a record 1,093 patents and became a skilled entrepreneur. Though occasionally unsuccessful, Edison and his team developed many practical devices in his "invention factory," and fostered faith in technological progress.
