HANOVER, N.H. — The Hood Museum of Art at Dartmouth College has acquired the complete archives of famed war photographer James Nachtwey, who also will provide the school with all the photographs he takes during the rest of his working life.

Nachtwey, a 1970 graduate of Dartmouth, has spent more than 35 years in conflict zones. He is currently a resident fellow at Dartmouth and will help catalog his archive, which includes more than half a million images.

Museum director John Stomberg says Nachtwey has an unparalleled eye for the human side of world affairs, and that the archive will allow the intersection between photography and society to be studied in depth.

Nachtwey, who started as a newspaper photographer in 1976, has been a contract photographer with TIME magazine since 1984.
