June 2012 was the 50th anniversary of the publication of Brian Josephson's famous paper: "Possible new effects in superconductive tunnelling", Physics Letters 1, 251 (1962). This anniversary was marked with a one-day meeting held in Cambridge on Saturday 23rd June 2012, with invited speakers covering the past, present and future of Josephson physics. The picture shows Kapitsa's crocodile, carved into the walls of the Royal Society Mond Laboratory where Brian Josephson did his original work. Slides for most of the talks are available at http://www.dspace.cam.ac.uk/handle/1810/243505.
