The Foundation Compositio Mathematica is the foundation behind the journals Compositio Mathematica and Algebraic Geometry. It has the aim of publishing first class papers in the central areas of mathematical research and supporting mathematics and mathematical research. Compositio Mathematica itself was founded in the 1930s by L.E.J. Brouwer (known from the Brouwer Fixed Point Theorem and one of the founders of Algebraic Topology) after his clash with Hilbert concerning Mathematische Annalen. The Foundation dates back from 1950. The journal was published for many years in cooperation with Kluwer Academic Publishers and its Dutch predecessors. In view of the ever rising journal prices the Foundation decided before the turn of the century to stop the cooperation with commercial publishers and opted for cooperation with the learned society The London Mathematical Society. The actual change took place on January 1, 2004. Printing and distribution are taken care of by Cambridge University Press.
Since the change of publisher the subscription price has been reduced considerably. The net result of this joint venture is fed back into mathematics via the London Mathematical Society and the Foundation Compositio Mathematica. The foundation supports mathematics via subsidies for mathematical conferences, prizes for mathematical accomplishments and other initiatives.
In 2014 the Foundation started the publication of the open access journal Algebraic Geometry. The Foundation also supports the open access journal Symmetry, Integrability and Geometry: Methods and Applications (SIGMA).
