Bernhard Tandberg (14 December 1856 – 21 June 1913) was a Norwegian farmer and politician.
He was born at Rustad in Lier as a son of farmers Hans Andreas Tandberg and Olava M. Skaugstad. He took secondary education in Drammen from 1867 to 1872, and later settled in Nes, Buskerud. He took over some forest owned by his father in 1881, and the family farm in 1887. He was also a timber merchant from 1886 and local savings bank director from 1888. He became a member of Nes municipal council in 1885, and served as mayor from 1892 to 1898. He was elected to the Parliament of Norway in 1900, representing the constituency of Buskeruds Amt. He did not win re-election until 1909. The constituency was now called Hallingdal, a single-member constituency.
Tandberg was an electronics manufacturer located in Oslo, Norway (product development, sales and distribution) and New York City, United States (sales and distribution). The company began in the radio field, but became more widely known for their reel-to-reel tape recorders and televisions. The original company went bankrupt in 1978 after a sharp financial downturn. The company re-formed by selling off their tape recording side as Tandberg Data, who moved into the computer storage field.
Over time the original Tandberg company became increasingly involved in the teleconferencing systems, and became a leader in that field. The company's main competitor was Polycom and other competitors were HP, Sony, Radvision, VTEL and Aethra.
Cisco Systems acquired Tandberg on 19 April 2010. Tandberg Data is now officially a German company, and continues to make computer tape storage systems.
The company was founded by Vebjørn Tandberg as Tandbergs Radiofabrikk (the Tandberg Radio Factory) in Oslo in 1933. The company's first radio was named "Tommeliten", and used only earphones. This was followed by the "Corona" with a loudspeaker. In 1934, the first "Huldra" radio was launched, followed in 1936 by the "Sølvsuper". During the early years, radios, loudspeakers and microphones were the main output from the factory. The Sølvsuper and the Huldra radios became the foundation for Tandberg's success.
