Tommy Bonnesen
Tommy Bonnesen (March 27, 1873 - March 14, 1935 ) was a Danish mathematician.
Bonnesen studied at the University of Copenhagen , where he received his doctorate in 1902 with the work Analytiske studier over ikke-euklidisk geometri (Analytical studies of non-Euclidean geometry ). He was Professor of Descriptive Geometry at the Polytechnic in Copenhagen .
He dealt with convex geometry (he wrote a book about it with his student Werner Fenchel ) and is known for inequalities named after him that generalize the isoperimetric inequality (using the radii of the ins and outs of the convex figures).
Together with Harald Bohr , he edited the Matematisk Tidsskrift of the Danish Mathematical Society for many years .
His daughter was the theater and film actress and musician Beatrice Bonnesen (1906–1979). His daughter Merete Bonnesen (1901–1980) was a journalist for the newspaper Politiken .
