The company was founded by engineers Arnold Poulsen and Axel Petersen in 1918. Initially focusing on sound film technology, Ortofon began to diversify into gramophone record playback and cutting equipment towards the end of World War II. The firm pioneered the use of moving coil technology in phonograph equipment; the first cutting head based on this technology was introduced in 1945. Ortofon’s first moving coil magnetic cartridge, the AB model, was launched in 1948, and similar variations of that product are still manufactured today due to demand from enthusiasts. 1959 the first Stereo Pick-Up SPU, which aimed at professionals, appeared. This pick-up is produced in different versions until today, for example SPU Meister in 1992, SPU 95th Anniversary in 2015. When Ortofon turned 80 years old, the MC Jubilee was introduced; first time Ortofon used a metal housing manufactured with Metal injection molding. 2000, on the occasion of the 250th anniversary of the death of the composer Johann Sebastian Bach, an MC-Series “Kontrapunkt” was presented. The models were named b, a, c, and h, wherein the b has a cantilever made of ruby. For the frame of the housing stainless steel was used. Successors of these pickups became the Cadenza series in 2009. Regarding the cantilever the Anna Diamond that appeared in 2019 should be mentioned: its cantilever is made of diamond.
