Career
Mayer was born 8 March 1911 at Rufach. He served with the Condor Legion in the Spanish Civil War with 1. Staffel, Jagdgruppe 88, claiming eight victories. On his return from Spain Oberleutnant Mayer was posted to 1. Staffel, Jagdgeschwader 53 (JG 53—53rd Fighter Wing), becoming Staffelkapitän (squadron leader) in October 1939. He claimed his first victory of World War II on 5 November 1939 downing a French Potez 63. Mayer claimed eight more victories during the Battle of France, including five aircraft shot down on 14 May 1940 alone. During the Battle of Britain he then shot down two Hurricanes over the Isle of Wight on 12 August 1940. On 25 August Mayer shot down a Hurricane for his 15th victory, that of F/L AWA Bayne (8 victories) of 17 Squadron, who baled out. The next day Mayer shot down two Spitfires. One of his victim was ace Sgt Cyril Babbage (7 victories) of No. 602 Squadron RAF, who baled out. Hauptmann Mayer was awarded the Ritterkreuz on 3 September.

Mayer was made Gruppenkommandeur I./JG 53 on 1 September 1940, and recorded his 30th victory on 15 September. On 17 October 1940 Mayer took off on a test flight and never returned, his body washing up on the English coast 10 days later. He was possibly a victim of RAF ace F/L D.
