							"The company was founded in 1924 by investors to 
							exploit the
							
							Neutrodyne patent of
							
							Dr. Louis Alan Hazeltine. Headquartered in 
							Greenlawn, Long Island, New York, since 1955, it had 
							facilities in several other locations in Long 
							Island, including its Wheeler Laboratories facility 
							in Smithtown, New York, manufacturing plants in 
							Riverhead and Little Neck, NY, and a division in 
							Braintree, Massachusetts. The company originally 
							concentrated on the design of electronic circuits 
							and the licensing of patents. Innovations in radio, 
							monochrome and later color television components 
							allowed the company to grow. One particularly 
							lucrative design was the
							
							Automatic Gain Control circuit. This was such a 
							useful feature that almost every AM radio made used 
							this feature, by license from Hazeltine, from about 
							1930 until the patent expired. Hazeltine Corporation 
							also developed and licensed some of the basic 
							concepts of the
							
							NTSC color television system. " |
