Oh. Here’s something else I learned that surprised me to an extent. An economics prof pointed this out to me (sadly) after he read the book. Princeton was incredibly racist in von Neumann’s day but von Neumann championed David Blackwell, when most others would not. This raised von Neumann, the man as opposed to the mathematician, to new heights for me when I was told about it. There’s a nice blog post on Blackwell which mentions the impact of this on him: https://stat.illinois.edu/news/2020-07-17/david-h-blackwell-profile-inspiration-and-perseverance
