GLENN WHARTON is a conservator in private practice in Los Angeles. He received his Master's degree from the Cooperstown Graduate Program in 1981. He interned at the Oriental Institute of the University of Chicago, J. Paul Getty Museum, and Fogg Museum. Following his internships, Mr. Wharton received an Andrew Mellon Fellowship at the Los Angeles County Museum of Art and a research fellowship at the Getty Conservation Institute. He has served as Field Conservator for the Cyprus Expedition of Princeton University, the Sardis Expedition of Harvard University, and the Institute of Nautical Archaeology in Turkey. Address: 549 Hot Springs Road, Santa Barbara, California 93108.
SUSAN LANSING MAISH received a Bachelor's degree in Fine Arts from the Art Center College of Design, Pasadena, California in 1984. Since 1986, she has been on staff of the Antiquities Conservation Department, J. Paul Getty Museum. Preceding her current position, she was a member of the Gilbert Silver Cleaning project at the Los Angeles County Museum of Art. Address: The J. Paul Getty Museum, Antiquites Conservation, P.O. Box 2112, Santa Monica, California 90406.
WILLIAM S. GINELL received his Ph.D. in Physical Chemistry from the University of Wisconsin. Since 1949, he has held research positions at Brookhaven National Laboratory, Atomics International, Aerospace Corporation, and McDonnell Douglas Astronautics Company. He joined the Getty Conservation Institute in 1984 as Head of the Materials Science Section. His principal research interests are in protective coatings for conservation, corrosion of metals, seismic damage mitigation methods for cultural property, and architectural conservation.
