In Mexico City, at the height of World War II, the Viennese expatriate artist Wolfgang Paalen founded and edited DYN, an international art journal that distinguished him as a theorist and scholar of modern and ethnographic art. The journal was instrumental in the development of avant-garde art in Mexico and New York, particularly Abstract Expressionism. In DYN, Paalen published his own essays, criticism, and poetry, and collections of Native American Art, along with the contributions of Latin American artists such as Manuel Álvarez Bravo, Miguel Covarrubias, César Moro, Carlos Mérida, Martín Chambi, and Roberto Matta; European artists Henry Moore, Alexander Calder, Marc Chagall, Gordon Onslow Ford, and Alice Rahon; New York artists Robert Motherwell, Jackson Pollock, David Smith, and William Baziotes; Mexican anthropologists and ethnologists Alfonso Caso, Miguel Angel Fernandez, and Carlos Margain Araujo; and writers Valentine Penrose, Henry Miller, and Anaïs Nin. The five issues of DYN published between 1942 and 1944 inspired artists and thinkers worldwide. In 1945, following Paalen’s one-man exhibitions in Mexico City and New York, Robert Motherwell edited Form and Sense, an anthology of the DYN essays.
