Von Weizsäcker, and his family, are extremely interesting. The father was a somewhat reluctant ambassador to Britain. The four brothers all were highly successful, as a physicist, a politician (President of Germany in the 90s), an economist, and a political scientist.

I had the honor to study with the economist. I rarely get the explicit idea that someone is smarter or dumber than me. But with him, it was so obvious I skipped right over jealousy straight to awe and enjoyment.

There is also a play, “Copenhagen”, featuring three or four possible versions of a meeting of WeizsÄcker. Heisenberg, and Bohr.
