I tracked Henri Cartier-Bresson (1908–2004) from England to India to Indonesia and back. He was in England for the coronation of King George VI; he was in India when Gandhi was assassinated; he was in Indonesia as the nation gained independence from the Dutch. He was seemingly everywhere.
I know because it was my job to compile all of Cartier-Bresson’s photo captions, notes, datebooks, and correspondence from his travels, which covered the better part of the 50 years he was actively working as a photographer. I then had to transform this into a comprehensive yet comprehensible chronology that would appear in the catalogue of the exhibition Henri Cartier-Bresson: The Modern Century.
