The Gems Sensors & Controls (Gems) story began over 50 years ago in 1955 when the company founder, Edward H. Moore, developed a level indicator in his basement. It was patented in 1959. Along with an associate, Gordon Seigle, he established the Gems Company (GS for Gordon Seigle, EM for Ed Moore). Gems' first commercial success was a bilge switch for the small boating industry. Rapid acceptance of Gems' products for marine and industrial applications led to continual expansion of facilities and staff - from a 6,500 sq. ft. building to a facility of 60,000 sq. ft. in Plainville, Connecticut, USA.
