The Royal Dutch Mathematical Society (Koninklijk Wiskundig Genootschap in Dutch, abbreviated as KWG) was founded in 1778. Its goal is to promote the development of mathematics, both from a theoretical and applied point of view.
The society publishes the quarterly journal Nieuw Archief voor Wiskunde, the magazine Pythagoras for high school children and the scientific journal Indagationes Mathematicae.
Every year the society organizes a winter symposium for high school teachers. Bi-annually it organizes the Dutch Mathematical Congress. Once every three years, the society awards the prestigious Brouwer Medal to a distinguished mathematician. This medal is named after L. E. J. Brouwer.
