David Taylor Galt was born on 10 November 1914 at Brunswick, Victoria to David Taylor and Martha Jane (née Singleton) Galt. He had a younger brother, Kenneth Rae Galt, and another brother that died in infancy. Galt grew up in Melbourne, Victoria and worked in the family flock manufacturing company. He married Elsie May Lees on 1 June 1940.

On 7 December 1940, Galt enlisted to serve in the Royal Australian Air Force at Melbourne. After his training, he was promoted to Pilot Officer and flew with 460 Squadron, Royal Australian Air Force (R.A.A.F.), based in the United Kingdom. In late November 1942, Galt was flying an Avro Lancaster on a bombing mission when his aircraft was shot and set alight. He crash landed in France, and all of the crew survived. Galt and two others of his crew evaded capture and returned to England. The remainder of his crew were found and became prisoners of war. On 9 February 1943, Galt was awarded a Distinguished Flying Cross for “displaying gallantry and coolness whilst flying”. He was also promoted to flying officer and transferred to 461 Squadron, R.A.A.F.

David Taylor Galt died in a flying battle over the Bay of Biscay on 13 August 1943. He and his crew were on anti-submarine patrol when they signalled that they were being attacked by six German aircraft. No traces of Galt’s aircraft or crew were ever found. David Taylor Galt is commemorated at Runnymede Memorial at Surrey, United Kingdom.
