Elihu Thomson
A brilliant but overlooked inventor whose electrical patents and business acumen literally powered the modern world.
1853–1937 (age 84)·English-American engineer and inventor·Birthday: March 29
Biography
While Edison and Tesla dominate the popular history of electricity, Elihu Thomson's steady genius was arguably more foundational. A self-taught prodigy, he patented his first invention, a process for making lead tubing, while still a teenager. His true legacy, however, was forged in the arc light and the alternating current system. Co-founding the Thomson-Houston Electric Company, he amassed hundreds of patents covering everything from electric welding to X-ray tubes. His company's merger with Edison's interests created General Electric, a titan built on Thomson's innovations. More a scientist than a showman, he preferred the laboratory to the limelight, solving practical problems with elegant engineering. His work didn't just invent devices; it built the industrial infrastructure that made widespread electrical power possible.
