1922 Thomas Edison Electrical Genius & Charles Steinmetz "The Wizard of Schenectady" Working in the Lab Original photo

Thomas Alva Edisonwas an American inventor and businessman, who has been described as America's greatest inventor. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park",he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory.Charles Steinmetzwas an American mathematician and electrical engineer and professor at Union College. He fostered the development of alternating current that made possible the expansion of the electric power industry in the United States, formulating mathematical theories for engineers. He made ground-breaking discoveries in the understanding of hysteresis that enabled engineers to design better electromagnetic apparatus equipment, especially electric motors for use in industry.At the time of his death, Steinmetz held over 200 patents. A genius in both mathematics and electronics, he did work that earned him the nicknames "Forger of Thunderbolts" and "The Wizard of Schenectady". Steinmetz's equation, Steinmetz solids, Steinmetz curves, and Steinmetz equivalent circuit are all named after him, as are numerous honors and scholarships, including the Charles Proteus Steinmetz Award, one of the highest technical recognitions given by the Institute of Electrical and Electronics Engineers professional society.Offered is an original crystal-clear photograph that measures 5.5" x 7" Thomas Edison and Hugo Steinmetz, the two wizards of electricity, as they worked on their latest projects in Edison's lab. The image was taken in 1922 and this example is certainly close to that date and we feel it is indeed a 1920's example with a slightly later 1930 file date from NEA on the back.Produced from the original negative.Handwritten caption on the back reads, "Photographed in Schenectady when Steinmetz showed destructive results of his artificial lighting to Edison."
