Like many an aspiring writer of the era, I reached out to Geoffrey Dutton and was chuffed to get back this letter. He was known for his support of young writers, including Michael Dransfield.

GEOFFREY DUTTON was one of the most prolific, versatile and talented writers in the literary history of Australia.
His contribution to Australian letters was probably unrivalled in his generation - a remarkable output of nine collections of poetry, eight novels (three for children), and critical studies, biographies of Australian writers and explorers as well as of the American poet, Walt Whitman, travel books and works of art appreciation: over 40 publications in all including, in 1994, a disarmingly frank autobiography, Out in the Open.
