William A. Leonard, professor emeritus of mathematics, died Sept. 24. He was 84.
Leonard earned his doctorate in mathematics education from the University of Northern Colorado in 1972 and joined Cal State Fullerton’s Mathematics Department that same year. He retired in 1998 but continued to teach part-time until 2003.
Colleagues called him “a dedicated teacher with a great deal of passion for the next generation of teachers.” He began his career as an engineer but moved over to teaching high school and then college-level math. He also was a popular speaker at math conferences around the country. Leonard authored “No Upper Limit — The Challenge of the Teaching of Secondary Mathematics,” a collection of unusual mathematics problems and their solutions.
He is survived by his wife, Esther; daughter Jill; two granddaughters; and four brothers.
