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 and the author of acclaimed books on Van Gogh, Constable and Michelangelo. He is the author of Man with a Blue Scarf, Rendez-vous with Art and A Bigger Message. He has collaborated with David Hockney on A Bigger Message and A History of Pictures, and has co-written a volume of travels and conversations with Philippe de Montebello: Rendez-vous with Art.
