Jack Koenig is The Donnell Institute Professor Emeritus of the Dept. of Macromolecular Science and Engineering at Case Western Reserve University in Cleveland, OH.

Koenig received his B.A. in Chemistry and Mathematics from Yankton College and his M.S. and Ph.D. in theoretical chemistry from the University of Nebraska. He worked briefly for DuPont in spectroscopic methods for the characterization of polymers before joining the faculty at Case Institute of Technology.

Koenig is a pioneer in spectroscopic methods of polymer characterization, playing a significant role in developing characterization methods to provide fundamental structure-property relationships for polymers used in thermoplastic and thermoset systems.

Combining a distinguished academic career with practical research directly applicable to industry, Koenig invented the infrared method of measuring branches in polyethylene and the method currently used to determine the molecular weight of insoluble PTFE polymers. Both of these have become ASTM standard test methods.
