Magnus Cormack  Sir Magnus Cameron Cormack KBE (12 February 1906 – 26 November 1994) was an Australian politician who served as a Senator for Victoria from 1951 to 1953 and from 1962 to 1978, representing the Liberal Party. He was President of the Senate from 1971 to 1974. Cormack was born on 12 February 1906 in Wick, Caithness, Scotland. He was the oldest of five children born to Violet () and William Petrie Cormack. His maternal grandfather John Macdonald Cameron was a Liberal Party member of the British House of Commons. Cormack's father, a medical doctor, decided to relocate to Australia for health reasons. A distant cousin was Sir Josiah Symon, a Senator for South Australia, who was also born in Wick. The family arrived in Adelaide in about 1912, and settled on the Eyre Peninsula south of Whyalla. Having begun his formal education in Scotland, Cormack attended a state school in Tumby Bay and then boarded at St Peter's College, Adelaide. From 1926 to 1931, he worked as a production manager with Holden. During the Great Depression, Cormack went into dairy farming. In later life he observed "I had three dairy farms, and I lost money on every one of them, so I claim to know something about dairying". By 1934, he and his brothers John and William had acquired "Koijak", a grazing property near Apsley, Victoria, close to the South Australian border. On 22 November 1935, Cormack married Mary Isabel Macmeikan (known as Mavis) at the registrar's office in Melbourne; she was a divorcee. The couple had four children together. Cormack enlisted in the Militia in July 1940, and was posted to anti-aircraft regiments at Puckapunyal and Werribee. He was discharged in October 1940, but re-enlisted in June 1941 and was commissioned as a lieutenant. He received postings to the Royal Military College, Duntroon, the headquarters of the Australian Imperial Force, and the Staff College. He transferred to the regular army in August 1942. In July 1943, Cormack arrived in Port Moresby as part of the headquarters staff of the II Corps. He moved to the New Guinea Force in January 1944, where he spent four months before leaving for Townsville and receiving his discharge. He finished the war with the rank of major and was mentioned in dispatches for "gallant and distinguished service in Papua". Cormack was a member of the Young Nationalists before the war, and joined the Liberal Party in 1946.
