Reparations, inflation and political crises: For the German industry, the post-war years are economically difficult. Lorenz focusses on government business, produces large broadcasting facilities for the Reichspost, supplies telephones, radio equipment and photo telegraphs for the transmission of mug shots to the police, and experiments with ultra-short waves. And the quality of electrical engineering made in Germany is also appreciated abroad. In 1921, they receive the order to set up a wireless intercom between the Danish capital Copenhagen and the island of Bornholm – an attention-getting reference for the fairly recent radiotelephony.
1921 A new star is born in the electronics sky
The Baltic German Georg von Schaub founds the G. Schaub Apparatebau-Gesellschaft mbH in Charlottenburg that has just been incorporated into Berlin. Schaub successfully produces simple crystal radio receivers, followed by tube receivers and radios. In 1934, the company moves to Pforzheim-Dillweißenstein.
1922 Production abroad
The Treaty of Versailles largely prohibits research and production in the field of military technology. The German industry is in danger of being left behind. One alternative is the foundation of phantom companies abroad. In 1922, the Royal Netherlands Navy needs modern and optomechanical fire control systems for their Java-class light cruisers. Siemens & Halske AG and the local switch box manufacturer Floris Hazemeyer therefore found NV Hazemeyers Fabriek van Signaalapparaten in Hengelo. The Dutch-German devices soon have export customers in Europe, Turkey and Latin America.
1924 Death of Robert Held
Robert Held dies unexpectedly on 9 December. Under his leadership, Lorenz has grown from a workshop to a global company with 3,000 employees within a quarter of a century.
1926 High up in the sky
The field of civil aviation grows. In 1926, Deutsche Luft Hansa AG arises from a series of mergers. The increasing traffic leads to an increased demand for aircraft radio equipment. In the following years, Lorenz equips numerous passenger and cargo planes, including the 12-engine flying boat Do-X.
