POLARIZED LIGHT MICROSCOPY IN CONSERVATION: A PERSONAL PERSPECTIVE

WALTER C. McCRONE



NOTES

1. Instruction in the use of the PLM for the conservator is available at graduate programs in art conservation and at independent facilities such as the McCrone Research Institute.

AUTHOR INFORMATION

WALTER C. MCCRONE received B. chem. and Ph.D. degrees from Cornell University. He worked at the Illionois Institute of Technology Research for 12 years before starting his own research laboratory, McCrone Associates, in 1956. His special interests have always been chemical microscopy, crystallography, and ultramicroanalysis. He has more than 350 technical publications, including 12 books. In 1960 he started the McCrone Research Institute, devoted to teaching and fundamental research. He is editor and publisher of the international applied journal of microscopy, The Microscope. He is an Honorary Member of the American Institute for Conservation, a Fellow of the International Institute for Conservation and the American Academy of Forensic Sciences, an Honorary Fellow of the Royal Microscopical Society, and a member of many other societies. He has received a number of awards: Benedetti-Pichler (1970), Ernst Abbe (1977), Anachem (1981), and Criminalist of the Year (1985), among others. Address: McCrone Research Institute, 2820 S. Michigan Ave., Chicago, Ill. 60616–3292.
