Ackerman, Ph.D., the William Greenleaf Eliot Professor of Chemistry and chair of that department, after the unveiling of his portrait at a Sept. 8 ceremony in the Arts & Sciences Laboratory Science Building. Weissman was one of six WUSTL chemistry professors honored for their significant contributions to the Manhattan Project. Family members of Joseph Kennedy, Lindsay Helmholz, David Lipkin, Herbert Potratz, Arthur Wahl and Weissman joined a crowd for the event, which included the 46th Joseph W. Kennedy Memorial Lecture, given by Robert J. Cava, Ph.D., professor and chair of Princeton University’s chemistry department. The WUSTL faculty of Arts & Sciences commissioned the painting of individual portraits by the local artist Gilbert Early.
