Richard Lindner was a German-American painter. "The artistic universe of Richard Lindner is unique: he is highly genuine, he is full of urban energy, and he is driven by weird eroticism.... Richard Lindner started his career as an artist eventually at the age of 40 in New York. In this metropolitan jungle Lindner created his oeuvre: exciting and powerful images of robot like figures, amazons and heroines, harlequins of self-styled heroes — his artistic panorama of the unruly '60s and '70s of the 20th century" (sic) (Claus Clement quoted in Richard Lindner –Paintings, Works on Paper, Graphic, Nuremberg 2001). One of Lindner's paintings, Boy With Machine, 1954, appears on the cover of Deleuze's Anti-Oedipus and thus the image has formed part of many readers' introduction to Deleuze's later and more accessible philosophy. Richard Lindner appeared in the second row on The Beatles's Sgt. Pepper's Lonely Hearts Club Band album cover.
