The Capa Cases
Three cardboard suitcases were found containing thousands of negatives of pictures that Robert Capa took during the Spanish Civil War in 1939, before he fled Europe for America leaving behind the contents of his Paris darkroom. The suitcases are currently at the International Center of Photography in Midtown Manhattan.
From the article The Capa Cache published in the New York Times by Randy Kennedy (January 27, 2008):
“This really is the holy grail of Capa work,” said Brian Wallis, the center’s chief curator, who added that besides the Capa negatives, the cracked, dust-covered boxes had also been found to contain Spanish Civil War images by Gerda Taro, Robert Capa’s partner professionally and at one time personally, and by David Seymour, known as Chim, who went on to found the influential Magnum photo agency with Capa.
The discovery has sent shock waves through the photography world, not least because it is hoped that the negatives could settle once and for all a question that has dogged Capa’s legacy: whether what may be his most famous picture — and one of the most famous war photographs of all time — was staged. Known as “The Falling Soldier,” it shows a Spanish Republican militiaman reeling backward at what appears to be the instant a bullet strikes his chest or head on a hillside near Córdoba in 1936. When the picture was first published in the French magazine Vu, it created a sensation and helped crystallize support for the Republican cause.
