Weaver, an American mathematician and one of the founders of communication theory, directed the Rockefeller Foundation's Natural Science Division from 1932 to 1955, and in this capacity exercised considerable influence over the direction of basic research in the United States and abroad during the 1930s and 1940s. From 1954 on he was first trustee, then vice president of the Sloan-Kettering Institute for Cancer Research in New York City (the "Institute" referred to in his letter).. In this letter Weaver expressed doubt that the reductionism at the heart of modern physics was suitable for the study of biology.
