Neomycin—Umezawa Claims,, 1948-1959

This file concerns claims by Dr. Umezawa to have discovered Neomycin first. SAW's letter to R. Dunham November 8, 1951 explains history of his discovery and evidence submitted by Umezawa, as well as copies of journal articles translated into English from the Japanese Medical Journal submitted by Umezawa from 1948-1950. NOTE: Photocopies of letters to/from SAW of very poor quality.
