The American James Abbe published superb photo documentaries from Stalin’s Moscow, about the last years of the Weimar Republic, and from the battlefields of the Spanish Civil War. Obsessed and fearless, Abbe got close to the dictators of Europe — Hitler, Mussolini, Franco. In 1932, he was the only American given permission to photograph Stalin. Photographs of the rulers of the world became his specialty — “Shooting dictators is great fun!”
