Tommy Bonnesen

He graduated from the Metropolitanskolen in 1892 and then began mathematical and natural science studies at University of Copenhagen.

In 1898, he received the university's gold medal for solving a prize problem, and in 1902, he earned his doctoral degree with the dissertation Analytical Studies on Non-Euclidean Geometry.

Tommy Bonnesen was a bright presence in the mathematical community of his time, known for his infectious humor and sharp wit.

In 1917, he was appointed professor of descriptive geometry at the Polytechnical School, where he worked until his death.

Together with Werner Fenchel, Bonnesen published the renowned mathematical classic Theory of Convex Bodies in 1934 through Springer-Verlag.
