Schwarzschild, Martin (1912-1997)
Allthought he never got to meet his
father he too went on to study
astronomy and in particular the structure of stars.
With John Von Neumann he was one of the first to use
a digital computer to model the internal structure of a star.
There is a story which I think refferes to
Martin (it is recounted in Kippnehan's 100 Billion suns
and I will check to provenance as soon as I can).
Martin was walking with his girlfriend, he was the first to realise
that nuclear energy must be powering the stars,
he turned to his girlfriend and said to her, at the moment I am the only one
in the world who knows how the stars shine, but she
was not too interested.
I heard another story about Martin from one of my professors, who
was a postdoc with him at Princeton. His father had developed
the instability criteria in stellar structure. My professor was continually
trying to get Martin to talk about this area of physics and managed to get him
cornered one day. Martin had to say "according to .... my fathers criteria .."
(hell it made me laugh)
