Fruit full-time work

In 1961,1 came to Houston again.. .. This provided at last an opportunity to spend full time in discovering how the electron capture detector really worked. In this I was fortunate to have nearby both Dr. Zlatkis who by then had become a close friend and colleague and Dr. Wentworth and Dr. Chen of the University of Houston. This fruitful collaboration led to the first plausible kinetic model of the electron capture detector. [2]... 

Ferry went to Harvard University in 1937 and worked there in a variety of posts, including as a Junior Fellow, until he joined the University of Wisconsin in 1946. He was promoted to Full Professor in 1947 His extensive measurements of the temperature dependence of the dynamic mechanical properties of polymers led to the concept of reduced variables in rheology. His demonstration that time-temperature superposition applied to many systems is the basis for the rational description of polymer rheology. He measured the dynamic response over a very wide range of frequency. One of the fruits of this work is the Williams-Landel-Ferry (WLF) equation for time-temperature shift factors.
