For a longer read, I can highly recommend the book "The Man from the Future" by Ananyo Bhattacharya. It's quite an easy read and extensively discusses the life and discoveries by John von Neumann in chronological order.

Not sure what just happened but like 10 comments just vanished. Anyway, here's a wiki link to "The Martians" which was a group of Hungarian scientists and Von Neuman was a member.

"The Martians" (Hungarian: "A marslakók") were a group of prominent scientists (mostly, but not exclusively, physicists and mathematicians) of Hungarian Jewish descent who emigrated from Europe to the United States in the early half of the 20th century.[1]

Leo Szilard jokingly suggested that Hungary was a front for aliens from Mars."
