Professor of Chemistry Dietmar Seyferth from The Massachusetts Institute of Technology lectured on "Organocobalt Cluster Compounds—Carbon in an Unusual Environment."  A specialist in the synthesis and characterization of organometallic compounds—compounds containing bonds between carbon and a metal—and in their reactivity and applications, Professor Seyferth was the founding regional editor of The Journal of Organometallic Chemistry between 1964 and 1981.
