John Bell
John Bell relaxing in his apartment in Geneva with a "Schneekupel" made by Renate Bertlmann, who also took this photograph. Bertlmann's husband, Reinhold, was a friend and colleague of Bell. In 1981 Bell published a paper called "Bertlmann's socks and the nature of reality" in which he explained the Einstein-Podolsky-Rosen paradox by analogy to Bertlmann's habit of wearing different-coloured socks.
