John Corbett (March 23, 1926 – September 2, 2013) was an American chemist who specialized in inorganic solid-state chemistry. At Iowa State and Ames Lab, Corbett lead a research group that focused on the synthesis and characterization of two broad classes of materials, notably Zintl phases and condensed transition metal halide clusters. Both classes of materials are important for their uses, for instance thermoelectrics, and for the theoretical advances they made possible by working to understand their complex bonding and electronic properties.
