ROME — Vittorio Foa, an anti-Fascist intellectual, labor union leader and senator whose life traced the trajectory of the Italian left in the 20th century, died Monday at his home in Formia, outside Rome. He was 98.

Walter Veltroni, the leader of the center-left opposition, announced his death to the ANSA news agency, speaking on behalf of the Foa family.

Born in 1910, Foa came of age under Fascism. In the 1930s, when he was in his 20s, he joined Giustizia e Liberta, or Justice and Liberty, an underground group of anti-Fascist activists in his native Turin. Many of them were Jewish, as he was, including Leone Ginzburg, the husband of the novelist Natalia Ginzburg. Foa was also close to Carlo Levi, who wrote “Christ Stopped at Eboli.”

In 1935, the Fascist authorities arrested Foa, with other Justice and Liberty leaders, and sentenced him to 15 years in prison. The Allies freed him in 1943.

In 1948, Foa became a leader of the left-wing CGIL labor union. In the 1950s, he was elected to Parliament as a member of the Socialist Party and later became a senator for other left-wing parties.
