Geoff Hook OAM (born 27 December 1928 in Hobart, Tasmania), better known as Jeff Hook, is an Australian artist and former editorial cartoonist.
Geoff has been married to Pauline since 1961 and has five children.
After attending St Virgil's College, Hobart, Hook started as a cadet press artist on the Hobart Mercury and completed a course in Graphic arts at the Hobart Technical College (now Tasmanian School of Art, a faculty of the University of Tasmania) which included tuition in Fine Arts under Jack Carington Smith, Margaret Chandler, Harry Buckey and Edith Holmes.
He started his career as a press artist and part-time cartoonist on the Hobart Mercury drawing under the name "Jeff". He moved to Melbourne and started at The Sun News-Pictorial in 1964. Geoff became the full-time cartoonist for The Sun News-Pictorial (later to be merged with the afternoon newspaper The Herald to become the Herald Sun) soon after. It was shortly after that Geoff started hiding in his cartoons what became his "trademark", a fish hook, and looking for the hidden fish hook became a widespread morning pastime amongst readers of The Sun News-Pictorial.
Geoff first gained international recognition in 1967 for his cartoon about the end of the Six Day War, "The three wiser men", which was republished widely outside of Australia, including in The Times.
In 1987, Geoff won the award for Humorous Illustration in the Australian Black and White Artists Club's Bulletin Awards. Also in 1987, Geoff won the award for the Best Political Cartoon at The International Cartoon Festival at Knokke-Heist, Belgium, and in 1991 he won the award for Best Press Cartoon at the same Festival.
