David Hockney (1937–2026) was one of the most influential British artists of the 20th century. He produced work in almost every medium – painting, drawing, stage design, photography and printmaking – and stretched the boundaries of all of them. His groundbreaking Secret Knowledge: Rediscovering the Lost Techniques of the Old Masters is published by Thames & Hudson, as are his books in partnership with Martin Gayford: A Bigger Message (2011), A History of Pictures (2016) and Spring Cannot be Cancelled (2021). Thames & Hudson also published the catalogue of his blockbuster exhibition at the Fondation Louis Vuitton in 2025. Martin Gayford is art critic for The Spectator. His books include Modernists & Mavericks, Man with a Blue Scarf, A Bigger Message, Rendez-vous with Art (with Philippe de Montebello), A History of Pictures (with David Hockney), and, most recently, The Pursuit of Art, all published by Thames & Hudson.
