History
Charles Proffer Saylor was born Camden, New Jersey in 1901. He earned a B.S. (1923) and Ph.D. (1928) in chemistry both from Cornell University. He was employed at the National Bureau of Standards (NBS) from 1931-1968.
At NBS he was a chemical microscopist in the Organic Chemistry section of the Chemistry division, and in 1950 was made the first Chief of the newly formed Pure Substances section. He also served as a consultant to the Analytical Chemistry division, and after his retirement in 1968 he continued working as a guest researcher in the NBS Institute of Materials Research.
Dr. Saylor’s principal fields were physical chemistry and chemical microscopy. He conducted research on the evaluation of purity of chemical substances and the obtainment of extreme purity, on chemical microscopy relating to formations of crystalline phases, crystalline rubber, optical properties of crystals, and refractive index of micro quantities of chemicals. He also worked out the problem of color phase contrast microscopy in 1950 with Nobel Prize winner Frits Zernike. Saylor patented the freezing staircase method of purification.
In 1961 Dr. Saylor was awarded the Department of Commerce Silver Medal for Meritorious Service which credited him for "highly significant contributions to microscopical techniques for the evaluation of pure substances.”
Charles P. Saylor died in Silver Spring, Maryland in 1982.
