"Indiens pas morts, an exceptional photo-essay documenting the lives of South American Indians, was only partially complete when French publisher Robert Delpire called on Robert Frank to aid in its publication. Progress had been halted when Magnum photographer Werner Bishof was killed on a Peru mountainside. Before his sudden death Bischof "won renown as an exceptional photographic witness of this time. One of the first to be invited into the Magnum agency," co-founded by Robert Capa, news of Bischof's death reached Vietnam only hours after news was announced of Capa's own tragic death by a mine outside Hanoi. Robert Frank, whose landmark photobook Les Américains would be published two years later by Delpire, here assisted the publisher by suplementing Indiens pas morts with 14 of his own photographs, taken on a 1948 trip to Peru."
