Dixon received a bachelor’s degree in mathematics from Oregon State College in 1938, a master’s degree from Wisconsin in 1939, and a Ph.D. in mathematical statistics from Princeton in 1944, under Samuel S. Wilks.
He was on the faculties at Oklahoma (1942-1943), Oregon (1946-1955), and UCLA (1955-1986, then emeritus). He was an operations analyst at Princeton and during the war, on Guam.
At UCLA, Dixon formed the biostatistics division in the School of Public Health and also organized and chaired the department of biomathematics in the School of Medicine. Dixon made major contributions to several areas in more than 120 publications, including the results of long-term collaborations in pharmacology, physiology, surgery, neurology, cytology, and psychiatry.
He was a fellow of the American Statistical Association, the Institute of Mathematical Statistics, the Royal Statistical Society, and the Association for the Advancement of Science. For two decades he was a career service volunteer for Princeton.
Dixon was predeceased by his first wife, Eva. He is survived by Glorya, his wife of 25 years; two daughters; and with Glorya, 14 grandchildren and five great-grandchildren.
