Steve Harrison, Gerard Bricogne. Steve, Gerard and Art Olson travelled to Paris for the CECAM workshop from Cambridge England. The group in Cambridge had prepared some of the input for the phasing computations to be done on the IBM 370 at CIRCE at the CECAM workshop. This photo shows Steve and Gerard after disembarking from the ferry at Calais, to catch the bus to Paris. The cart was mostly filled with boxes of punch cards for the computations.
