David Gentle has been a consultant, an engineer and a marketeer, travelling from Baku to Tokyo in the process. But the one true constant has been his love of trivia. He is author of the popular quiz books The Ministry of Quizzes and On the Tip of My Tongue. He lives in the UK near Bath with his much-quizzed wife and two sons. His ambition is to one day write the perfect quiz question, and with more than 10,000 attempts to date, feels he has made a good start.
