Just discovered the work of Manuel Alvarez Bravo, friend of Tina Modotti (who was herself a student of Edward Weston) and colleague of Diego Rivera. Bravo taught at Chicago's Hull House and exhibited alongside Cartier-Bresson and Walker Evans in New York. He was also the cameraman on Eisenstein's heretofore mentioned Que Viva Mexico.
I'm ashamed that I've never heard of him -- along with all the other astonishing talent from Central and South America that we generally ignore up North.
A portfolio of Bravo's photography is available for browsing online »
