Jack M. Williams
Jack Marvin Williams is an American chemist who contributed to the development of organic superconductors.
Early life and career
Born in Delta, Colorado, he earned his BSc from Lewis & Clark College in 1960 and his PhD in physical and inorganic chemistry from Washington State University in 1966.After obtaining his PhD, he served as a postdoctoral fellow at Argonne National Laboratory in Illinois for two years. He was promoted to the positions of assistant chemist in 1968, associate chemist in 1970, chemist in 1972, and senior chemist in 1977. Additionally, he led the chemistry, material science, and technology divisions from 1977 onwards.
He also served as a visiting guest professor at the University of Missouri in 1980 and 1981 and at the University of Copenhagen in 1980 and 1985. He was also the chairman of the Gordon Research Conferences in 1980.
He retired from ANL in 1997 for health reasons.
Research
His early research focused on elucidating the properties of chemical bonds using X-ray diffraction and neutron diffraction. Attending the International Conference on Synthetic Metals in 1979 in Helsingør, Denmark, where Klaus Bechgaard and Denis Jérome reported on the superconducting behavior of 2PF6, introduced him to superconductivity in organic charge-transfer complexes. Upon returning to ANL, he built up aprogram in organic conductors and superconductors.
He played a role in the development of organic superconductors in the United States. Building his background in structural and inorganic chemistry, he proposed design approaches for inorganic anions in organic charge-transfer complexes, which contributed to the discovery of several organic superconductors, including κ-type BEDT-TTF salts, by his research group.
