I read a note on Peter Minkowski's page of
the passing of Markus Fierz earlier this year.
The name Fierz is known to everyone in
elementary particle physics due to his
transformations. However, until I met
Peter in 1994-95, I was not even aware that
he was a contemporary figure. Peter, who
had been a graduate student of Fierz's has
linked a pdf file on his home page on the
life and times of Fierz.
