was renowned for his work in the field of inorganic chemistry, particularly his pioneering research into the direct chemical bonding of pairs and clusters of atoms of elements known as transition metals. He discovered and analyzed many compounds that contain double or multiple metal-metal bonds, including the first known metal-metal quadruple bonds (1964). In explaining the nature of metal-metal bonding and of bonding between metal and carbon atoms in organometallic molecules, Cotton's work was highly important in helping to understand catalysts, substances that increase the rate of a chemical reaction without being consumed in the reaction and that are essential in biological systems and certain industrial processes. Cotton received an A.B. (1951) from Temple University, Philadelphia, and a Ph.D. (1955) in chemistry from Harvard University. He joined (1955) the faculty of the Massachusetts Institute of Technology as an instructor, and in 1961 he became the youngest person at MIT to achieve the rank of full professor. In 1972 Cotton moved to Texas A&M University as a professor in the chemistry department, and in 1982 he was also appointed director of the Laboratory for Molecular Structure and Bonding. Among his awards were the National (U.S.) Medal of Science (1982), the Priestley Medal (1998) of the American Chemical Society, and the Wolf Foundation Prize in Chemistry (2000). Cotton also wrote a number of leading chemistry textbooks.
