Sir Albert Cherbury David Rivett, KCMG (4 December 1885 – 1 April 1961) was an Australian chemist and science administrator. Background and education Rivett was born at Port Esperance, Tasmania, Australia, a son of the Rev. Albert Rivett (1855–1934), a noted pacifist. He studied at Wesley College, Melbourne and the University of Melbourne, where he was a member of Queen's College, Melbourne, obtaining a Bachelor of Science degree in 1906 and a Doctor of Science degree in 1913. He was a Rhodes Scholar at Lincoln College, Oxford, where he did research under the supervision of Nevil Sidgwick in the laboratories of Magdalen College, Oxford. He was awarded a Bachelor of Arts degree with First Class Honours in 1909, and a Bachelor of Science degree with First Class Honours in 1910. Career In 1910 Rivett spent six months at the Nobel Institute of Physical Chemistry at Stockholm working with the Director, Svante Arrhenius. In 1911 he returned to Australia as Lecturer in Chemistry at the University of Melbourne. On 11 November 1911 he married Stella Deakin, daughter of Alfred Deakin, a former Prime Minister of Australia. Stella, a research chemist, had first met David when both were students at the University of Melbourne. In 1914 he was organising secretary of the 84th meeting of the British Association for the Advancement of Science, with the committee chaired by David Orme Masson. This was the first time the meeting had been held outside the United Kingdom. Rivett left extensive archives of this meeting. Rivett was away from Australia during World War I from 1915 to 1919. In August 1915 he accepted a commission in the Australian Army Medical Corps Reserve, but from 1917 he was involved in the production of pure ammonium nitrate, used for explosives, at the British munitions works at Swindon. The understanding gained there led to the publication in 1924 of The Phase Rule and the Study of Heterogeneous Equilibria, and to an appreciation of the value of fundamental research for industrial applications. He became Associate Professor at the University of Melbourne in 1921 and succeeded Professor David Orme Masson, with whom he had previously worked, as Professor of Chemistry in 1924. From 1923 to 1927, he lived in what is now University House at the University of Melbourne. He was Deputy chairman and chief executive officer, 'Council for Scientific and Industrial Research' (CSIR) from 1927 to 1946 and Chairman
