Thomas Edison

On February 11, 1847, in Milan, Ohio, Thomas Edison was born into a family that soon moved to Port Huron, Michigan. Limited formal schooling pushed him toward self-directed study, telegraph work, and relentless mechanical experimentation from his teenage years onward. Employment as an operator gave him both technical knowledge and entry into national communications networks.

Edison built his research center at Menlo Park, patented the phonograph in 1877, and developed a practical incandescent lighting system by 1879. He also promoted central electric stations, film technologies, and a business model that tied invention directly to organized capital and patents. His career made the laboratory itself a productive institution in the industrial economy.

Edison's methods influenced later corporate research centers such as those of General Electric and other large industrial firms. Electric lighting, recorded sound, and motion pictures all grew into major industries through patterns of innovation and commercialization he helped establish.
