N. G. W. H. Beeger

From Wikipedia, the free encyclopedia

Nicolaas George Wijnand Henri Beeger (1884, in Utrecht – 1965, in Amsterdam) was a Dutch mathematician. His 1916 doctorate was on Dirichlet series. He worked for most of his life as a teacher, working on mathematics papers in his spare evenings. After his retirement as a teacher at 65, he began corresponding with many contemporary mathematicians and dedicated himself to his work.

He is known for having proved that 3511 is a Wieferich prime in 1922 [1] and for introducing the term Carmichael number in 1950.

Beeger Lecture[edit]

In 1989 the board of trustees of the Mathematical Centre in Amsterdam established the Beeger lectures, in honor of N.G.W.H. Begger, to be held biannually at the congress of the Royal Dutch Mathematical Society. Their purpose is to promote research and exchange of ideas in the field of algorithmic and computational number theory. The first Beeger Lecture was delivered in 1992.
