Hermann Brunn

Karl Hermann Brunn (1 August 1862 – 20 September 1939) was a German mathematician, known for his work in convex geometry (see Brunn–Minkowski inequality) and in knot theory. Brunnian links are named after him, as his 1892 article "Über Verkettung" included examples of such links.

Life and work

Hermann Brunn was born in Rome, and grew up in Munich.[1] He studied mathematics and physics at the Ludwig Maximilian University of Munich, graduating in 1887 with the thesis Über Ovale und Eiflächen (About ovals and eggforms).[2] He habilitated in 1889.
