Hitchcock’s forgotten Holocaust documentary

In 1945, film director Alfred Hitchcock, born on this day in 1899, embarked on a difficult journey: Documenting the Nazi atrocities in liberated death camps across Europe. The film, “German Concentration Camps Factual Survey,” was to be a “lesson for all mankind.” This is the story of the world-famous film director whose powerful film was lost and forgotten for 70 years.
