“Discussion: John Von Neumann—A Case Study of Scientific Creativity”, William Aspray, Peter Horvath, Dénes Nagy, Edward Teller, Nicholas Vonneuman, Eugene P. Wigner1989-07 (math)⁠:

[followup to Halmos1973] Edward Teller assesses John von Neumann’s influence on the development of mathematics, especially of his work on representation theory of non-compact groups. He stresses von Neumann’s early realization of the importance of computers.
