KURT MISLOW, professor emeritus of chemistry, died Oct. 5 in Princeton. He was 94. Mislow was on the faculty from 1964 to 1988 and chaired the chemistry department from 1968 to 1974. He was a pioneer in the theory of modern stereochemistry, which analyzes the three-dimensional arrangement of molecules and atoms in space. Its importance extends to fields including genetics and biochemistry. He authored or co-authored more than 350 journal articles and in 1965 wrote Introduction to Stereochemistry, a book that is still used in teaching.
