Dezső Szentgyörgyi was born in 1915 in Kőkút. He finished his studies in Enying, and was 18 years old when he volunteered for the Royal Hungarian Air Force. Initially he was an aircraft-mechanic, but later received pilot training. He finished the aviation school in Székesfehérvár with excellent ratings. He was trained as a fighter pilot, and took part in 1/2 FS’s operations in northern Hungary with the Fiat CR.32. In summer 1942 he was transferred with the 1/1 "Dongó" Fighter Squadron to the Soviet front. He flew the Reggiane Re.2000 Falco, then the Messerschmitt Bf 109G. He shot down his first aircraft on 7 August 1942 in a friendly fire accident, while flying a Re.2000. The victim being a German Heinkel He 111 bomber that opened fire on him during while Szentgyörgyi was trying to identify the aircraft. His first victory over an enemy fighter was almost a year later, 26 June 1943, a Soviet fighter, a Yak-1 or Yak-7, on Gresnoje. His record on the Eastern Front was 142 sorties and 6 kills.

The 101. Honi Légvédelmi Vadászrepülő Osztály was formed on 1 May 1944. Szentgyörgyi was transferred to the 101/2 "Retek" Fighter Squadron. He continued to score his kills among the Pumas, and shot down 6 American planes. By the summer of 1944 he was a flight leader. He was promoted to Ensign on 16 November 1944. After the "American Season" ended, once again Soviet fighters became the main enemy. Dezső scored an additional 17 kills. He achieved his last air victory on 16 April 1945: a Yak-9 on Guttenbrunn. He never crashed a plane due to pilot error, and he was never shot down. By the end of the war he had completed more than 220 sorties, and had 29 confirmed kills; the most successful Hungarian fighter pilot.
After the war, he returned home and became a pilot of the MASZOVLET between 1946 and 1949. Between 1950 and 1956 he spent several years in Communist prisons, before becoming a pilot of the renamed Malév Hungarian Airlines again, logging 12,334 flight hours and covering more than 5 million kilometres in the air.
