RAF Planes that won the Battle of Britain were built on German Machinery: How Jewish Refugee Engineer, Ludwig Loewy was crucial to the war effort

Ludwig Loewy was a Jewish engineer who left Nazi Germany in 1936 to set up an engineering firm in London as a refugee. Britain was re-arming and a new generation of aircraft was being developed based on light alloy construction. The new Loewy Engineering Company had expertise to supply presses and rolling mills required for alloy fabrication which were otherwise supplied from Germany at a time of growing tension. The new firm also built a giant tube press for steel for the Admiralty.
Loewy’s new company grew rapidly in London, helped by a workforce of refugee engineers and managers and “many thousands” of machinery drawings from Germany. Loewy became a technical advisor to the British Government’s production programme for aircraft until his death in 1942.
Back in Germany, Loewy’s former firm, Schloemann in Düsseldorf, was Aryanised after his departure. Schloemann continued to supply equipment into the UK until the outbreak of war and went on to help the German and Italian war effort. Ludwig was dispossessed of his major share in the Company and the history of Schloemann was re-written.
Ludwig Loewy’s rapid assimilation owed much to earlier contacts with the UK engineering and metals establishment, his expertise in a sector that was growing rapidly and short of skills, customers who needed his technology and his own personal energy and drive. The Government welcomed his contribution to aircraft and warship production at a time of break-neck re-armament. Ludwig Loewy’s experience supports the view that German speaking refugee engineers were readily accepted in the UK over the period 1933 to 1945.
