Athanasius Treweek

Lieutenant Colonel Athanasius Pryor "Ath" Treweek (1911–1995) was an Australian academic, linguist, mathematician and code-breaker. He was the son of Walter Henry Treweek and Mary Matilda Dwyer a nurse. They married in Cooma, New South Wales, Australia on 11 February 1909. She was 37 and he was 43. He was an only child and his father died in 1920 of the Spanish influenza when Ath was 8 years old. His mother could work as a nurse only by living in at a hospital, so he was sent to a boarding school in Bowral.
