Robert James Diamond (24 October 1916 - 5 April 2002) was an Australian mathematician, physicist and teacher. He is best known for his work in the academic field. Early life Family Diamond was born in Rockhampton, Queensland to parents Henry Diamond and Amelia Jane Diamond (née Comollatti). He was the second youngest of four children. Diamond's mother Amelia was a member of a large Italian Australian family, whose patriarch Antonio Comollatti had settled in Duaringa in Central Queensland after first arriving in Australia from Italy in 1862. After marrying Ann Reed in Rockhampton in 1876, Antonio became a naturalised Australian citizen in November 1893. Amelia was one of Antonio and Ann Comollatti's ten children, being one of only two daughters. Amelia married Henry Diamond in 1911 and after initially living in Duaringa, moved to Rockhampton where they raised Diamond and his three brothers - Henry Vincent (Harry), Stuart Gibson (Stu) and Ronald Fitzroy (Ron). When Diamond was 8 years old, his father Henry died in July 1925. Diamond suffered personal tragedy again in 1932 when his eldest brother Harry Diamond, a promising rugby league player, died at the age of 21 in August 1932 after an illness. His death occurred less than six months following the death in March 1932 of their maternal grandmother Ann Comollatti (née Reed). Education While growing up in Rockhampton, Diamond attended Central Boys State School until 1929 when he obtained a scholarship to continue his secondary education at Rockhampton State High School where he passed his junior examinations in 1931 before graduating from the school in 1933. Upon graduating from Rockhampton State High School, Diamond showed his potential for further success when he achieved the highest marks in Australia after undertaking the Commonwealth Public Service Examinations. This enabled him to receive a scholarship to attend the University of Queensland in Brisbane. At university, he studied science and graduated with a Bachelor of Science in 1937. Career After graduating from university Diamond worked as a teacher at a number of private schools throughout New South Wales and Queensland including Scots College and Barker College before returning to Rockhampton in 1945 to take up a position as senior mathematics and chemistry master at the Rockhampton Grammar School. While back in Rockhampton, Diamond was elected to a committee in 1945 that had been created to advocate for the establishment of more adult education services in the city. Diamond
