everyone else in the camp, prisoners and guards alike, as someone who managed to preserve his humanity. After the war, Lorenzo could not cope with the memories of what he had seen, and descended into alcoholism. Levi made several trips to rescue his old friend from the streets, but in 1952 Lorenzo died. In gratitude for his kindness in Auschwitz, Levi named both of his children, Lisa Lorenza and Renzo, after him. In 1950, having demonstrated his chemical talents to Accatti, Levi was promoted to Technical Director at SIVA. As SIVA's principal chemist and trouble shooter, Levi travelled abroad. He made several trips to Germany and carefully engineered his contacts with senior German businessmen and scientists.

In 1954 he visited Buchenwald to mark the ninth anniversary of the camp's liberation from the Nazis. Levi dutifully attended many such anniversary events over the years and recounted his own experiences. In July 1957, his son Renzo was born.

As one of Levi's primary reasons for writing the book was to get the German people to realise what had been done in their name, and to accept at least partial responsibility, this translation was perhaps the most significant to him. 1961–1974 Levi began writing The Truce early in 1961; it was published in 1963, almost 16 years after his first book. That year it won the first annual Premio Campiello literary award. It is often published in one volume with If This Is a Man, as it covers his long return through eastern Europe from Auschwitz. Levi's reputation was growing. He regularly contributed articles to , the Turin newspaper. He worked to gain a reputation as a writer about subjects other than surviving Auschwitz. In 1963, he suffered his first major bout of
