history
In 1850 the merchant Martin Kothe founded the trading company Kothe, but died a year later. With the entry of the authorized signatory Ernst Leybold , the company "Leybold & Kothe" was founded in May 1851 , which concentrated on the sale of pharmaceutical and physical-technical equipment and apparatus. In 1863 Leybold took over the company completely and sold it on in 1870, resulting in the company name (company) E. Leybold's successor , which was used for a long time in 1967 .
This was followed by the abandonment of the pharmaceutical division and the focus on teaching aids , before the production of vacuum pumps was established from 1906 . The development of the molecular pump (1911), the mercury diffusion pump (1913) and the gas ballast device for pumping out vapors with rotating vacuum pumps (1935) resulted from the collaboration with Wolfgang Gaede .
The company was converted into a stock corporation in 1922 and a KG in 1936 . In 1948 and 1955, respectively, Metallgesellschaft AG and Degussa AG acquired their first holdings in E. Leybold's successor .
In July 1967 E. Leybold's successor merged with Heraeus Hochvakuum GmbH. The shareholders of the new “Leybold Heraeus GmbH” were in equal parts Degussa AG , Metallgesellschaft AG and WC Heraeus GmbH.
After Metallgesellschaft and WC Heraeus separated from their shares in September 1987, “Leybold Heraeus GmbH” was converted into “Leybold AG” and the company's headquarters were relocated from Cologne to Hanau .
In November 1994 Degussa sold Leybold to the Swiss Oerlikon-Bührle Group, which Leybold merged with Balzers AG, which it already owned, to form the “Balzers and Leybold Group”. The merger resulted in one of the world's largest vacuum and surface technology companies , which in 1995 had around 6,500 employees and achieved sales of DM 1.8 billion .
In 2000 Degussa sold the remaining teaching material division, which today - after bankruptcy in 2008 - operates under the name LD Didactic and is based in Hürth near Cologne .
In 2006, as part of a group-wide renaming, “Leybold Vacuum” became “Oerlikon Leybold Vacuum GmbH”.
According to its own information, Leybold is one of the world's most important providers of vacuum technology in the business areas of process industry , information technology , analysis methods and research and development . The company has production sites, service centers and commercial branches in Germany , Switzerland , France , Great Britain , Italy , the Netherlands , Belgium , Sweden , Spain , the USA , Brazil , China , Japan , Taiwan , Korea , Singapore and India . Internationally, Leybold has a wide network of more than 80 distributors and agents.
On November 20, 2015, OC Oerlikon announced the intended sale of the Oerlikon Leybold Vacuum division to Atlas Copco . The sale of the division was completed on September 1, 2016 and the company was renamed Leybold GmbH . Leybold is integrated into the Vacuum Technique division of the Atlas Copco Group.
