The story behind Osvald Jensen

Year 1911
The beginning
Osvald Jensen A/S was founded in 1911 by Osvald Jensen, a skilled precision mechanic trained at Lauritz Knudsen. He started his business with a friend in a small room in Kattesundet, Copenhagen, where they repaired cinema machines for the newly established film industry. After his friend emigrated to the USA, Osvald continued alone and received support from wholesaler Salomonsen to develop a teletypewriter.

Year 1914
Expansion and Innovation
The company moved to Rahbeks Allé no. 20, but the teletype project was abandoned at the outbreak of World War I in 1914. Instead, Osvald Jensen turned to the production of carburetors, which became a great success during the war. The company moved to larger premises at Vesterbrogade 112 in 1915 and continued to produce carburetors until the 1920s.

1920s & 1930s
New Challenges and Growth
The 1920s and 1930s were a difficult period for the company, which struggled with a lack of sales opportunities for their carburetors. However, Osvald Jensen found new sources of income by becoming a subcontractor to the automotive industry and Copenhagen Tramways. In 1935, we started manufacturing electric gramophone movements, which became a new success.

Year 1960
Wartime and Post-war period
During World War II, the company adapted by producing gas burners for vehicles when gasoline supplies were scarce. After the war, the production of gramophone movements continued and became an important source of income. The company grew and moved to new premises on Amerikavej in 1960 and later to Industrivej in Glostrup in 1985.

Year 1985
CNC Age Beginner
In 1985, the third generation took over management with Jens Peter Jensen and Søren Jensen as directors. The company continued to be a major player in the manufacture of precision components and retained the innovative spirit founded by Osvald Jensen. Under the new management and based on their technical know-how, Osvald Jensen A/S became a market-leading Danish manufacturing company that still develops small customer-designed gears and sprockets, and produces its own worm gears, which we market ourselves.

Lotte Bruun Jensen: Fourth Generation at the Helm
In 2014, Lotte Bruun Jensen took over the management of Osvald Jensen A/S from her father, Jens Peter Jensen. Lotte has been part of the board since she was 18 years old and has worked closely with her father to ensure a smooth transition. She holds a degree in Mechanical Engineering from DTU and continues to modernize and expand the company. Lotte works to maintain our image as a loyal, trustworthy and value-creating partner.

The Pair of Pairs
The team: Lotte Bruun Jensen and Christian Viereck
Lotte Bruun Jensen works closely with Christian Viereck, who joined the company in 2004 and later became COO. Christian is a trained toolmaker and later a mechanical engineer. Together they work to ensure that the company can develop and adapt to the demands of the future. Their collaboration strengthens the company's focus on quality, innovation and sustainability. They implement sustainable practices in production to minimize environmental impact and ensure a more responsible future.

She balances her role as CEO with her family life and works actively to ensure that our knowledge and traditions are passed on to future generations.
