Reuters reports Leopold Engleitner, the oldest known survivor of the Nazi concentration camps, has died at the age of 107, his biographer said.
Yahoo News further quotes Reuters to say Engleitner, a conscientious objector whose life was documented in the book and film "Unbroken Will", was imprisoned in the Buchenwald, Niederhagen and Ravensbrueck camps between 1939 and 1943.
Englietner was eventually released, weighing just 28 kilograms (62 pounds), on condition that he agree to spend the rest of his life working as a slave agricultural laborer.
Yahoo News says that according to Reuters he became a public figure when Austrian author and film producer Bernhard Rammerstorfer published his biography and a documentary film about his life in 1999, which were translated into English in 2004.
He went on speaking tours in Europe and the United States and talked to students about his experiences through his last years, attending the U.S. premiere of a new Rammerstorfer documentary film about his life in November 2012, concludes the report from Yahoo News and Reuters.
