Martin Aigner

Martin Aigner was an influential Austrian mathematician who specialized in combinatorial mathematics and graph theory. As a professor at Freie Universität Berlin from 1974, he made significant contributions to mathematical research and education through his academic work and publications. His most renowned work is "Proofs from THE BOOK," co-authored with Günter M. Ziegler, which has been translated into 12 languages and earned them the prestigious Leroy P. Steele Prize for Mathematical Exposition in 2018. The book presents elegant proofs of mathematical theorems, inspired by Paul Erdős's idea of a divine book containing perfect mathematical proofs. Aigner's academic excellence was recognized with several awards, including the 1996 Lester R. Ford Award from the Mathematical Association of America for his article on Turán's Graph Theorem. His other significant works include "Combinatorial Theory," which has become a standard reference in the field of combinatorial mathematics. Having received his Ph.D. from the University of Vienna, Aigner dedicated his career to advancing mathematical knowledge until his death in 2023 at the age of 81. His work continues to influence mathematicians and students worldwide through his published works and academic contributions.
