Sennheiser
Fritz Sennheiser founded the Wennebostel Laboratory (Labor W) in June 1945. At first, the companys main business was the production of measuring instruments, which it sold to Siemens. The farmhouse where the company was founded is still used as a business location today. The company changed its name to Sennheiser Electronic in 1958 and officially changed its legal name to Sennheiser Electronic GmbH&&Co. KG in 1996. In 1945, Siemens commissioned W-Lab to replicate a microphone from an Austrian supplier, which was launched in 1946 as the MD 1. In the same year, Sennheiser began developing its own microphone: the MD 2. From 1947 onwards, the companys microphone product line continued to expand.
