Photo conservation is a small but crucially important field, and one of its key players, Doug Severson, has retired from his position at the Art Institute of Chicago, where he had worked since 1977. Sylvie Pénichon, former photograph conservator at the Amon Carter Museum, is the new photo conservator, beginning December 30. Pénichon has just published Twentieth-Century Color Photographs: Identification and Care (Getty, 2013) to coincide with Color! American Photography Transformed, at the Amon Carter Museum through January 5. She is returning to the Art Institute, where she had been the Mellon Fellow in Photo Conservation from 1998 to 2001. Her current job will involve overseeing a three-year $280,000 grant from the National Endowment for the Humanities to assess and catalogue the permanent collection at the Art Institute.
