Passage: The unhappy Tambroni experiment tarnished Gronchi’s reputation for good, and until the end of his period of office he remained a lame-duck President. In 1962 he attempted to get a second mandate, with the powerful help of Enrico Mattei, but the attempt failed and Antonio Segni was elected instead. As he ceased to be Head of State, he became a life senator by right, according to the Italian Constitution. He died in Rome on 17 October 1978 at the age of 91.
