About Lenox Hewitt
Sir Cyrus Lenox Simson Hewitt was an Australian public servant. His career in the Commonwealth Public Service spanned from 1939 to 1980, and included periods as a senior adviser and departmental secretary. His most prominent position was as secretary of the Prime Minister's Department during the Gorton government (1968–1971). He worked closely with Prime Minister John Gorton, although his initial appointment in place of John Bunting was seen as unconventional. Hewitt was also influential as secretary of the Department of Minerals and Energy during the Whitlam government (1972–1975), working under minister Rex Connor. He later served as chairman of Qantas (1975–1980). Hewitt was appointed Secretary of the newly created Department of the Environment, Aborigines and the Arts. On return to Australia he joined the Department of the Treasury, where a position of Assistant Secretary was specially created for him. The new Minister for Minerals and Energy, Rex Connor, had established a good relationship with Sir Lenox Hewitt in the period leading up to the election, and he chose him to be the first Secretary of the Department of Minerals and Energy.
