I don't want any publicity

"I don't want any publicity – you get too many begging letters. If they're anything like the ones I send out I don't want to know!"

Tony Hancock (1924-1968)

William K. Estes

Died 17 Aug 2011 at age 92 (born 17 Jun 1919).William Kaye Estes was an American psychologist who was a leader in bringing mathematical methods into psychological research. In 1977, he was awarded the National Medal of Science for “his fundamental theories of cognition and learning that transformed the field of experimental psychology. His pioneering methods of quantitative modeling and an insistence on rigor and precision established the standard for modern psychological science.” In his early professional research he partnered with another pioneering psychologist B. F. Skinner in studying animal learning and behavior. The quantitative method they devised to measure emotional reactions is still widely used today. From 1979, Estes focussed on investigating human memory and classification learning.
