The company was founded in 1945, just a few weeks after the end of World War II, by Fritz Sennheiser (1912–2010)[2][3] and seven fellow engineers of the University of Hannover in a laboratory called Laboratorium Wennebostel (shortened, "Lab W"). The laboratory was named after the village of Wennebostel in the municipality of Wedemark to where it had been moved due to the war. Its first product was a voltmeter.
