Clarence Melvin Zener (December 1, 1905 – July 2, 1993) was the American physicist who in 1934[1] was the first to describe the property concerning the breakdown of electrical insulators. These findings were later exploited by Bell Labs in the development of the Zener diode, which was duly named after him.[2] Zener was a theoretical physicist with a background in mathematics who conducted research in a wide range of subjects including: superconductivity, metallurgy, ferromagnetism, elasticity, fracture mechanics, diffusion, and geometric programming.
Life
Zener was born in Indianapolis, Indiana, the son of German-descent Clarence and Ida Zener, and brother of Katharine Zener (later Mrs Katharine Hurmiston) and psychologist Karl Zener, and earned his PhD in physics under Edwin Kemble at Harvard in 1929. His thesis was titled Quantum Mechanics of the Formation of Certain Types of Diatomic Molecules. In 1957 he received the Bingham Medal for his work in rheology, in 1959 the John Price Wetherill Medal from The Franklin Institute, in 1965 the Albert Souveur Achievement Award, in 1974 the Gold Medal[3] from American Society for Metals, in 1982 the Von Hippel Award[4] from the Materials Research Society, and in 1985 received the ICIFUAS (International Conference on Internal Friction and Ultrasonic Attenuation in Solids) Prize for the discovery of the Zener effect, pioneering studies of anelasticity in metals[5] and prediction and observation of thermoelastic damping. ICIFUAS Prize was later renamed after Zener, following his death in 1993.[6] A notable doctoral student of Zener's was John B. Goodenough, Nobel Prize winner in chemistry in 2019, and Arthur S. Nowick held a postdoctoral appointment under Zener.
Zener was known both for his dislike of experimental work and for preferring to work on practical problems within the arena of applied physics. Although he had a reputation of being very successful in these endeavors, he apparently considered himself as being less qualified to work on purely theoretical physics problems. In recognition of this, he once commented, after having dined with physicist J. Robert Oppenheimer: "when it came to fundamental physics, it was clear there was no point in competing with a person like that."[10]
