Rudolf Erren Explained

Rudolf Arnold Erren (15 August 1899 – death date unknown) was a German engineer and inventor who did important work on the use of hydrogen fuels in the early 20th century. He had several patents, developed the Erren engine,[1] and his work was "apparently the earliest reported use of hydrogen-engine supercharging of any kind."[2] One of Germany's World War II U-boats supposedly had a hydrogen engine designed by Erren.[3]

Erren was born in Prussia, served in both the German Army and Air Force during World War I, then became a police officer, and was "acquitted of a charge of murdering a superior officer."[4] Erren was interned in Canada by the British during World War II[5] and repatriated 28 October 1945.[6] He may have applied for British naturalisation in 1946.[7] He returned to Germany and remarried. Erren's research records were lost during WWII.

Erren's ex-wife Rosalie Mercy Burlin Erren Henderson (married 1931, divorced 1937) was one of John Haigh's murder victims.[8]
