was also elected onto the Rockhampton School of Arts committee in 1946. In 1947, he left Australia and relocated to the United States after he was accepted as a post graduate student at the California Institute of Technology in Pasadena. After studying at Caltech for three years, he graduated in 1951 as a Doctor of Philosophy with a mathematics major and a physics minor. His dissertation was titled "A Type of Pseudo-Norm". Diamond returned to Australia following his graduation from Caltech, keen to share his experiences with higher education in America. He was appointed as the head of the Ipswich Grammar School in December 1951. At just 37 years old, it was noted that Diamond was considered young for the position. In February 1953, Diamond resigned from the position at Ipswich Grammar after just two years in the role. He then returned to America where he began working in the aerospace field, employed by Lockheed Corporation and Meteorology Research Inc - a company founded by Paul MacCready. In 1956, he co-authored Studies of Contrails from Jet Powered Aircraft. In 1958, he was appointed as an assistant professor of mathematics at California State College in Los Angeles. He continued working in America throughout the 1960s and 1970s, despite revealing in a letter to his uncle in 1964 that he had attempted to find work back in Australia by applying for a position as professor of mathematics at the University of Queensland in Brisbane. In 1965, Diamond was elected to a three-year term as an executive committee member for the 51-member Academic Senate at California State College. Diamond had several articles published in journals in the 1960s including in the Philosophy of Science and the British Journal for the Philosophy of Science. This included a discussion in 1964 about how to resolve the paradox of Tristram Shandy, which had been explored by Bertrand Russell in his book The Principles of Mathematics. Views Politics Throughout the 1940s and 1950s, Diamond and his brothers were actively involved in the local branches of the Queensland People's Party which ultimately became the Queensland division of the Liberal Party of Australia. In the 1940s, Diamond served as honorary secretary and then president of the Rockhampton branch of the QPP while his older brother Stu Diamond served as chairman of the Allenstown branch of the party. In 1950, Diamond's younger brother Ron was preselected to be the Liberal
