This text discusses the institutionalization of mathematics research in Brazil with emphasis on the cooperation networks involving Brazil and Germany. These cooperation networks began systematically at the Institute de Matemática Pura e Aplicada [IMPA] (Institute of Pure and Applied Mathematics) in Rio de Janeiro, Brazil. An example is the work of the Brazilian mathematician Paulo Ribenboim at Bonn University and his contact with the German mathematician Wolfgang Krull. Another example is the contribution from the German mathematician Otto Endler in Brazil. Another collaboration arose during the 1990s: Michael Otte and his work preparing Brazilian researchers for the investigation of the history of mathematics.
