“Charles Proteus Steinmetz, already a distinguished industrial scientist, was hard at work as GE’s chief consulting engineer. After years of persuasion, Steinmetz convinced the GE leadership that the company would need a research laboratory to maintain its edge in lighting and electricity and also finding new areas to grow.” – Heritage of Research
Charles Proteus Steinmetz He made ground-breaking discoveries in the understanding of hysteresis that enabled engineers to better design electric motors for use in industry.
Siemens is one of the world’s largest technology companies. Siemens has six major business divisions: Communication and Information, Automation and Control, Power Generation, Transmission and Distribution, Transportation and Automotive, Medical, and Lighting.
Siemens – Industrial Technology
Siemens & Halske was founded by Werner von Siemens and Johann Georg Halske on 12 October 1847. Based on the telegraph, his invention used a needle to point to the sequence of letters, instead of using Morse code. The company, then called Telegraphen-Bauanstalt von Siemens & Halske, opened its first workshop on October 12. – Wikipedia – Siemens
