Old Lyme, CT - Apr 18, 2002 - Electroacoustical engineer Prof. Dr. Fritz Sennheiser celebrates his 90th birthday on May 9, 2002. As founder of Sennheiser Electronic GmbH, he brought many of the audio industry's watershed products to market, including the radio standard MD 2 and MD 21 microphones, the shotgun microphone (MD 82), the Mikroport wireless microphone system in 1958, the HD 414 open headphones, infrared transmission technology such as the HiDyn RF noise reduction, and DVD-quality microphone technology (MKH 800: 20Hz - 50,000kHz).

Sennheiser founded the company in 1945 with a team of seven engineers. Twenty years ago, Sennheiser handed management of the company to his son, Prof. Dr. Jörg Sennheiser, the current chairman of the supervisory Board of the Sennheiser Group. Sennheiser Senior still plays an active role in the company's activities.
