At just over five feet tall, Benjamin Ferencz had to stand on a pile of books to see over the lectern and into the faces of the defendants in his first ever trial.
He was just 27 when he became chief prosecutor for the US, bringing to justice members of the Einsatzgruppen - the Nazi death squads who murdered indiscriminately.
But Mr Ferencz was not daunted - he knew he had truth on his side when he stared at the 22 Nazi Party members accused of the most heinous crimes against humanity the world had ever seen.
