He is the best known of the four musketeers who founded Gamma in November 1966, taking charge of the agency after the parting of the ways. I wanted to hear his side of the story, but the photographer, who took President François Holland’s official portrait one year ago, is difficult to reach. When I finally got through to him, he was reluctant at first: “The anniversary of Sygma. I’m in no position to talk about it—I’m anti-Sygma!” A few days later, he called me back and kindly answered a few questions. Forty years later, despite his written contribution to the memoirs of Hubert Henrotte (which Depardon claims not to have read), we feel that the conflict of April and May 1973 is still vivid in his mind. The reason is his almost visceral attachment to Gamma, which led him again last month to offer his support to François Lochon, the agency’s current director.
