Sidney George Brown

Born 6 Jul 1873; died 1948 .American-born British electrical engineer, inventor and radio pioneer with over 1000 patents. He patented the first solid state detector to be useful in a receiving apparatus on 3 Jun 1904. It was actually a solid state electrolytic detector but its macroscopic characteristics were so similar to those of a crystal detector that it was later catalogued with the latter for sales purposes. In 1911, he founded the SG Brown Company which concentrated primarily on designing and manufacturing navigation and communication products for the military and commercial marine industry. SG Brown became famous, over the years, for highly accurate and reliable auto-pilot and gyrocompass products.
