Tommy Bonnesen (27 March 1873 – 14 March 1935) was a Danish mathematician, known for Bonnesen's inequality .
Bonnesen studied at the University of Copenhagen , where in 1902 he received his Ph.D. (promotion) with thesis Analytiske studier over ikke-euklidisk geometri (Analytic studies of non-Euclidean geometry). [1] He was the Professor for Descriptive Geometry at the Polytekniske Læreanstalt .
He did research on convex geometry and wrote a book on this subject with his student Werner Fenchel . Bonessen was an Invited Speaker at the ICM in 1924 in Toronto and in 1928 in Bologna.
With Harald Bohr he was for many years the co-editor-in-chief of the Matematisk Tidsskrift of the Danish Mathematical Society .
His younger daughter was the theatrical and cinematic star Beatrice Bonnesen (1906–1979). His elder daughter Merete Bonnesen (1901–1980) was a journalist employed by the newspaper Politiken .
