Leutnant (later Major) Alfred Lindenberger was a World War I flying ace credited with twelve aerial victories. He also scored four victories during World War II.
While Lindenberger was a gunner in FA 234, he shot down a Spad with pilot Vizfeldwebel Breitenstein on 29 May 1917. Then he was teamed with ace pilot Vizfeldwebel Karl Jentsch, and they scored two more SPADs in October. After pilot training, in May 1918 Lindenberger was posted to Jasta 2. Between 30 May and 1 November 1918, he downed nine more enemy planes, seven flying the Fokker D.VII.
In June 1944, Major Lindenberger served with JG 3 and then flew air defense sorties with JG 300 over Germany until February 1945. He was made II./ JG 300 Gruppenkommandeur in October 1944. Owing to his age and inexperience with modern fighters he flew most sorties as a wingman. On 28 September 1944 he claimed a B-17 over Hildesheim and a P-51 Mustang near Quedlinburg before he was shot down by P-51s and wounded. Lindenberger then claimed two US B-24 four-engined bombers on 17 December 1944 during a 15th Air Force raid over Poland, (JG 300 claimed 22 B-24s downed).
He thus scored four World War II victories in total, making his lifetime tally sixteen aerial victories.
