Christian Reiher (born 19 April 1984 in Starnberg) is a German mathematician. He is the fifth most successful participant in the history of the International Mathematical Olympiad, having won four gold medals in the years 2000 to 2003 and a bronze medal in 1999. ^[1]

Just after finishing his Abitur , he proved Kemnitz's conjecture, an important problem in the theory of zero-sums. ^[2] He went on to earn his Diplom in mathematics from the Ludwig Maximilian University of Munich.

Reiher received his Dr. rer. nat. from the University of Rostock under supervision of Hans-Dietrich Gronau  [ de ] in February 2010 (Thesis: A proof of the theorem according to which every prime number possesses property B) ^[3] and works now at the University of Hamburg. ^[4]
