JENSEN COMPANY HISTORY
Peter Laurits Jensen dedicated his life to innovation, today’s Jensen® musical instrument speakers continue the essence of this innovation.
Peter Jensen was born in 1886 in Falster, Denmark. At the 1900 Paris Exposition he made a public demonstration of the telegraphone, in 1909 he moved to the United States, working in the laboratory of radio pioneer Valdemar Poulsen.
Two years later, working alongside Edwin Pridham in a small laboratory of Napa – California, Peter Jensen experimented with Poulsen’s arc radio transmitter, adding thicker wires connected to a diaphragm and putting a coil of copper wire between magnets, thus making a working model of what they called the “electro-dynamic principle” for voice reproduction. Jensen applied this principle at a Christmas celebration, surprising the townspeople who heard the spoken voice amplified throughout their township.
In 1915, Peter Jensen and Edwin Pridham developed the “Magnavox”, the first loudspeaker. On December the 10th Jensen made the first public demonstration at the Golden Gate Park, on the 25th he played music in front of the San Francisco City Hall.
Magnavox speakers were predominantly used for public address systems, famously used in 1919 to amplify President Woodrow Wilson’s speech in San Diego.
