William B. Wiegand (February 17, 1889 – August 18, 1976)[1][2] was a Canadian-born research chemist and later a chemicals industry executive.
Wiegand developed a type of heat engine, the rubber pendulum, based on the Gough-Joule effect.
[3] Later in his career, he studied carbon black's reinforcing effect on rubber, and proposed that the effect arises due to forces acting at the interface between the carbon black and the surrounding elastomer matrix.
He was a pioneer in developing the furnace method for producing carbon black.
[7] Wiegand was born in Conestogo, Ontario, Canada on February 17, 1889.
