Donald F. St.Mary was Elected National Membership in the Danforth Associate Program, 1977. His talk ``Experiences of a Black Scientist, and some current research'', was presented at the National Science Foundation in celebration of Black History month, 1986. He served (1986-91) Committee on Equal Opportunities in Science and Engineering, Congressionally mandated committee of the National Science Foundation. In 1993 he as a Distinguished Scholar Designee of the Third Annual Celebration of Black Scholarship in New England, Boston.
