Robert F. Landel

Robert F. Landel (born October 10, 1925) is an American physical chemist at the Jet Propulsion Laboratory noted for his contribution to development of the Williams–Landel–Ferry equation,^[1]^[2] and for a particular form of hyperelastic energy function, the Valanis-Landel form.^[3]

Early life and education[edit]

Landel was born in Pendleton, New York on October 10, 1925.^[4] He was a combat infantryman in World War II, serving in eastern France and southern Germany (1943–1946).

Landel earned an MA in 1951 and a BA in 1950, from the University of Buffalo.^[5] He completed postdoctoral research under Prof. John D. Ferry at University of Wisconsin.

Career[edit]

Landel worked for Jet Propulsion Lab on solid rocket propellants as a physical chemist. He holds six patents.

Honors and awards[edit]

Robert F. Landel was elected vice president of the Society of Rheology in 1984.^[6]

In 2006, he won the Charles Goodyear Medal, bestowed by the American Chemical Society, Rubber Division to individuals who "have been the principal inventor(s), innovator(s), or developer(s) of a significant change or contribution to the rubber industry".^[7]
