On June 26-27, 2012, one of us (BBB) made a video based on an interview conducted with Andrew A. Benson, Professor Emeritus, Scripps Institution of Oceanography, University of California, San Diego, CA, USA. The video was first shown in a seminar presented by BBB on July 27, 2012 at the Calvin Laboratory, University of California, Berkeley, to mark the departure of the Energy Biosciences Institute to a new building. Here we record the conversation taking place during the interview. The Brancraft Library on the Berkeley campus will house the video's transcript in its oral histories collection, and the video will be housed in its motion picture collection. The video and the transcript have also been posted on You Tube (http://youtu.be/GfQQJ2vR_xE).
