Gerrit Bol

Gerrit Bol (1970)

Gerrit Bol (born May 29, 1906 in Amsterdam , † 1989 ) was a Dutch mathematician who dealt with geometry .

Bol received his doctorate in 1928 at the University of Leiden ( Vlakke Laguerre-Meetkunde , level Laguerre geometry) with Willem van der Woude . In the 1930s he worked with Wilhelm Blaschke at the University of Hamburg on the geometry of tissues (in this area “Bol Loops” are named after him, introduced in tissues and groups , 1937) and later on projective differential geometry. In 1931 he received his habilitation. In November 1933, Bol signed the German professors' confession of Adolf Hitler . In 1938, on the recommendation of Blaschke, Bol received a teaching position at the University of Freiburg , for which William Threlfall had originally been in discussion. Bol fought as a soldier on the Dutch side in 1940 and became a German prisoner of war who was released on Blaschke's intercession. With a three-year break, when he was associate professor at the University of Greifswald from 1942 to 1945 , he stayed in Freiburg until his retirement in 1971, from 1948 as full professor.

Heinz Kunle and Martin Barner are among his doctoral students .

Gerrit Bol is the father of the classical archaeologist Peter Cornelis Bol .
