Donald Dines Wall (August 13, 1921 – November 28, 2000) was an American mathematician working primarily on number theory.
He obtained his Ph.D. on normal numbers from University of California, Berkeley in 1949, where his adviser was Derrick Henry Lehmer.
In April 1940 he had a successful operation to remove a brain tumor at UC Hospital in San Francisco.
In the fall of 1947, he returned to graduate school at Harvard University, where he became interested in number theory.
In June 1948 he returned to California to complete his Ph.D. at UC Berkeley, where he also taught classes as a teaching assistant.
He traveled to interested universities in the western US to give them details of a program developed by the UCLA Anderson School of Management about the use of computers in business.
