Grosch to receive Charles Goodyear Medal.

Karl-Alfred Grosch, a pioneer in friction and wear phenomena, has been chosen as the 2007 recipient of the Charles Goodyear Medal. The most prestigious award given by the Rubber Division, ACS, honors an individual for outstanding invention, innovation or development which resulted in significant change or contribution to the nature of the rubber industry. The award will be presented during the 171st Technical Meeting, April 30-May 2, 2007, in Akron, OH.

Grosch was born in Trannroda, Thuringia, Germany, in 1923. He received a B.S. (Special Physics) from the University of London in 1958 and a Ph.D. (Science) from the school in 1963 under the supervision of Professor D. Tabor of Cambridge and L.R.G. Treloar of Manchester University with the subject "Friction and abrasion of rubber." He began his professional career as a laboratory assistant at the Malaysian Rubber Producers Research Association (MRPRA) in 1955 and was named the principal scientific officer in 1963. During this time, he worked with Adolph Schallamach and assisted him with his work on abrasion.

During this time, he established that rolling friction and grip on dry roads are governed by the viscoelastic properties of rubber, but that the two cases involve different effective frequencies of deformation. This made it possible to understand how tread compounds could be developed to function well under both conditions, giving low rolling friction and high friction for traction and braking.

Grosch left MRPRA in 1969 and joined the European Tire Development Center of Uniroyal in Germany as tire evaluation manager. In 1975, he became development manager for Commercial Tires, a position which he held until his retirement in 1988.

After his retirement, Grosch returned to research on friction and abrasion of rubber privately and developed the concept of the LAT 100 laboratory friction and abrasion test equipment which is now marketed by VMI Holland BV. He developed testing programs for the LAT 100 for wet traction, friction on ice and abrasion over a wide range of severities, and suitable software for the evaluation of results, including road test simulations, which agree well with reality. The system is used widely in the tire industry to develop new tread compounds.

He was awarded the Colwyn Medal of the British Institute of Materials in 1997. Grosch has presented a number of papers at Rubber Division, ACS meetings and International Rubber Conferences. He has published papers in Rubber Chemistry and Technology, Proc Royal Soc. and other journals, and has authored numerous chapters on friction and abrasion in several books.

Other 2007 Rubber Division Science & Technology Award winners include Daniel L. Hertz, Jr., who will receive the Melvin Mooney Distinguished Technology Award, Burak Erman, who will receive the George S. Whitby Award, William Mars, who will receive the Sparks-Thomas Award, and Dale J. Meier, who will receive the Chemistry of Thermoplastic Elastomers Award.
