Wedemark, Germany - May 9, 2007 - Prof. Dr. Fritz Sennheiser celebrated his 95th birthday on May 9. In June 1945 Sennheiser founded his Laboratorium Wennebostel with a staff of seven employees in an abandoned laboratory of Hanover's Technical University. Today, more than 1,650 people work for Sennheiser throughout the world, and the company has production sites in Germany, Ireland and the United States.
Born in Berlin, Sennheiser grew up to experience and to influence many developments in electroacoustics and transmission technology. Even as a young boy, he had a keen interest in all things technical. "I built my own radio receiver in 1924 from a slide coil and a crystal," the 95-year-old said. His passion for making new discoveries has accompanied Sennheiser throughout his life. He describes it as his creative restlessness.
The family company's innovations include the shotgun microphone in the 1950s, open-back headphones in the 1960s, infrared transmission technology in the 1970s and developments in multi-channel wireless technology in the early 1980s.
In 1982, Fritz Sennheiser handed the management of the company over to his son, Joerg Sennheiser, who is today chairman of the Supervisory Board.
