AUTHOR INFORMATION

ERIC F. HANSEN is a Fellow of the AIC who graduated from the University of California at Irvine in 1980 with an M.S. in organic chemistry and joined the Getty Conservation Institute in 1985. In his current position as an associate scientist, he is pursuing his interests in the environmentally induced deterioration of synthetic and natural organic materials (including collagen, fibroin, and keratin), the conservation of ethnographic and archaeological objects, and the analysis of the effects of treatment parameters on the final physical and optical properties of treated objects. Address: Getty Conservation Institute, 4503 Glencoe Ave., Marina del Rey, Calif. 90292.

ROSA LOWINGER is the director of the Sculpture Conservation Studio, a conservation facility in Los Angeles for the preservation of sculpture and decorative arts. In her 10 years in private practice, Lowinger has worked with numerous institutions and public agencies, including the City of Los Angeles, the National Park Service, and the U. S. Navy. She has an M. A. in conservation from the Institute of Fine Arts, New York University, and has been a fellow at the Los Angeles County Museum of Art and the University Museum, University of Pennsylvania. Address: Sculpture Conservation Studio, 1144 South Stanley Ave., Los Angeles, Calif. 90019.

EILEEN SADOFF is employed in the objects conservation laboratory at the Los Angeles County Museum of Art. From 1988–90 she assisted Eric Hansen with the development of the ethnographic training course at the Getty Conservation Institute. She was most specifically involved with facsimile research and manufacture to replicate the problems associated with powdery matte pigments on indigenous artifacts, and with testing of consolidants and application techniques for this type of object. She received a B.A. in art from the University of Minnesota, Address: Los Angeles County Museum of Art, Conservation Center, 5905 Wilshire Blvd., Los Angeles, Calif. 90036.
