Don Manley (born 2 June 1945) is a long-serving setter of crosswords in the UK.
He writes under the pseudonyms Duck, Pasquale, Quixote, Bradman, Giovanni, and Izetti (all punningly connected with the name Don or Donald).
Don Manley was brought up in Cullompton, Devon, attending local state schools and Blundell's School, Tiverton as a Foundation Scholar.
After a short spell in a telecommunications laboratory, he worked in academic and educational publishing at The Institute of Physics, Stanley Thornes, Basil Blackwell, and Oxford University Press, which he left in 2002 when crosswords took over as his sole paid occupation.
He is married to Dr Susan Manley, a clinical biochemist.
