Thomas Cairns, Conservation Chemist for the Los Angeles County Museum of Art, received his PhD degree in chemical spec­ troscopy from the University of Glasgow, Scotland, in 1965. He joined Heyden and Son, Ltd., as publishing director in 1965 and served in this capacity until his ap­ pointment at the Museum in June 1968. Dr. Cairns was editor and author of the series, "Spectroscopy in Education," Heyden, 1967, and is the author of numerous papers dealing with hydrogen bonding in natural products. He was a sum­ mer session lecturer in chemistry at UCLA, 1968—71, and is a science advisor to the Food and Drug Ad­ ministration in Los Angeles. Cur­ rently, Dr. Cairns is engaged in the application of mass spectrometry in an attempt to establish the origin of art objects via their trace analysis.
