Dora Mayer (Hamburg, 1886 - Lima, 1951) was a self-taught researcher, writer and journalist, social fighter and a german-peruvian activist. Mayer published numerous critical reflections on the performance of the political classes, the danger of foreign interventionism, and the backwardness and mistreatment of the indigenous as a colonial heritage that the Peruvian Republic had not been able to overcome. In "The Indigenous and Latin American Congresses", the author discusses the role of national political parties and advocates the creation of Pan-American alliances, as well as the defense of indigenous communities.
