W.K. & K.W. Estes Fund

William K. Estes (June 17, 1919 – August 17, 2011) had an enormous influence on psychological science, from his pioneering work in mathematical psychology to his collaborations with colleagues to his mentoring of students, many of whom are now leaders in the fields of learning and memory. He was recognized for his lifetime of donations with our Nation’s highest scientific honor, The National Medal of Science. The APS Observer featured remembrances written by leading researchers and close friends of Bill. This special collection is a celebration of his life and achievements.

Bill also had a special role in APS’s history and success as Founding Editor of our flagship journal Psychological Science. During those years, his wife, Katherine W. (Kay) Estes, served as Founding Managing Editor. Bill and Kay were a team in so many undertakings. The W.K. & K.W. Estes Fund celebrates their donations to psychological science.
