AUTHOR INFORMATION

MARION F. MECKLENBURG has worked as a paintings conservator in the United States for 20 years. He holds B.S., M.S., and Ph.D. degrees in structural engineering from the University of Maryland. In 1987, he joined the Smithsonian Institution and is currently the assistant director of conservation research at the Conservation Analytical Laboratory. He is also a fellow in the Department of Materials Science, Johns Hopkins University, where he coordinates the joint CAL-JHU Ph.D. graduate program in materials science. His research areas are in the mechanics of materials and the effect of the environment on the mechanical properties of materials. Address: Conservation Analytical Laboratory, Smithsonian Institution, Washington, D. C. 20560.

MARK H. McCORMICK-GOODHART joined the Smithsonian Institution in 1988 and is currently a research photographic scientist at the Conservation Analytical Laboratory. He holds a B.S. degree in photographic science from Rochester Institute of Technology. From 1976 to 1988 he was employed by Energy Conversion Devices, Inc., where he was granted eight U.S. patents related to nonsilver film and electronic imaging technology. His research interests concern the effects of environment on structural properties of photographs, and cold storage of photographic materials. Address: Same as for Mecklenburg.

CHARLES S. TUMOSA is head of analytical services at the Conservation Analytical Laboratory and has been at the Smithsonian Institution for five years. He has a Ph.D. in chemistry from Virginia Polytechnic Institute and State University, Blacksburg, Virginia, research interests include the analysis of trace materials and the mechanical properties of materials. Address: Same as for Mecklenburg.
