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).
