About John Flinders Petrie
John Flinders Petrie (1907-1972) was the only son of Egyptologist Sir W. M. Flinders Petrie. He was born in 1907 and as a schoolboy showed remarkable promise of mathematical ability. In periods of intense concentration he could answer questions about complicated four-dimensional objects by visualizing them.
He first realized the importance of the regular skew polygons which appear on the surface of regular polyhedra and higher polytopes. He was a lifelong friend of Coxeter, who named these polygons after him.
The idea of Petrie polygons was later extended to semiregular polytopes. http://en.wikipedia.org/wiki/John_Flinders_Petrie
In 1972, a few months after his retirement, Petrie was killed by a car while attempting to cross a motorway near his home in Surrey.
