In being named the 1969 Ames Award winner, Dr. Udenfriend added to a long list of honors which have come his way since he began his scientific career in 1940. In 1967, he received the Van Slyke and Gairdner Awards. Prior to that he had been cited with superior service awards by the Department of Health, Education, and Welfare, in addition to receiving such other prizes as the Hillebrand Award of the Washington Section, ACS, the Arthur S.
