Gehman was born on December 7, 1903. He died in Akron, Ohio, on June 1, 1992.[3]
In 1922, he was one of eight sophomores selected for honors at the University of Pennsylvania.[4] He completed his doctoral dissertation in 1929 on the topic Reflection of Soft X-rays.[5]
Gehman was recruited to Goodyear by Ray P. Dinsmore. He made influential studies of strain crystallization via x-rays,[6] of rubber's dynamic properties,[7] and of heat transfer in rubber.[8] He managed physics research at Goodyear's research division and was renowned for developing the Gehman low-temperature twist test, which gave laboratories convenient and precise low-temperature stiffening measurements of rubber compounds.[9] He was an inventor of approximately 70 patents.[10]
In 1972, Gehman was listed at 10th out of the 100 top contributors to the world's rubber literature published between 1932 and 1970.[11]
Gehman retired in 1968 following 40 years with Goodyear Tire & Rubber Co.
