John von Neumann
modernMathematical Philosophy, Philosophy of Science1903 – 1957
John von Neumann (1903–1957) was a Hungarian-American mathematician and polymath whose work spanned pure mathematics, quantum mechanics, economics, and computer science. He co-founded game theory with Oskar Morgenstern and developed the minimax theorem, laying the formal groundwork for rational decision theory. His contributions to the foundations of quantum mechanics and the architecture of digital computers place him among the most consequential scientific minds of the twentieth century.
