About Carlo Tresca
Lived 1879 – 1943 (aged 63). Carlo Tresca was an American and Italian journalist, editor, writer, trade unionist and labor movement.
Carlo Tresca (March 9, 1879 – January 11, 1943) was an Italian-American dissident, newspaper editor, orator, and labor organizer and activist who was a leader of the Industrial Workers of the World during the 1910s. He is remembered as a leading public opponent of fascism, Stalinism, and Mafia infiltration of the trade unions for the purposes of labor racketeering and corruption.
Born, raised, and educated in Italy, Tresca was editor of an Italian socialist newspaper and secretary of the Italian Federation of Railroad Workers before he emigrated to the United States in 1904. After a three-year spell as secretary of the Italian Socialist Federation of North America, he joined the Industrial Workers of the World in 1912, and was involved in strikes across the United States over the rest of the decade. He was jailed in 1925 after printing a paid advertisement for a birth control pamphlet in one of his newspapers.
During the 1930s, Tresca was a vocal critic of the Italian Fascist government of Benito Mussolini and the Soviet Communist government of Joseph Stalin. In 1937, he was a member of the Dewey Commission, which cleared Leon Trotsky of all charges made during the Moscow Trials. Tresca also used his newspapers to mount a public campaign criticising the Mafia. He was assassinated in New York in January 1943, allegedly by Carmine Galante.
Personal life Tresca was born on March 9, 1879, in Sulmona, Abruzzo, Italy, the son of a landowner. His formal education reached to secondary school. He enrolled at a seminary instead but left soon afterward and emerged as an anticlerical and an atheist. He also had a relationship with sculptor Minna Harkavy, whose bust of him was erected in his birth town of Sulmona.
American years
In the United States, Tresca was elected Secretary of the Italian Socialist Federation of North America in 1904. He remained in that position for the next three years.
In August 1923, Tresca was arrested on charges of having printed an advertisement for a birth control pamphlet in his new publication, Il Martello (The Hammer). Tresca edited an anti-fascist newspaper named Il Martello, where he attacked the myths that undergirded Mussolini's power. Tresca was monitored by the United States Department of Justice, who sought to deport him, and by Rome, where Mussolini feared that Italian-Americans would hurt his reputation with the United States and its banks. With pressure from the Italian ambassador to ban Tresca's newspaper, the American government charged Tresca with publishing obscenities. Tresca was sentenced and subject to deportation, but public dissent led the United States President Calvin Coolidge to commute Tresca's sentence. The fascists turned to violence, with a bombing assassination attempt in 1926, after which the antifascists fought back. Tresca contributed towards stopping Mussolini's ideological spread among Italian-Americans, despite Tresca's lack of reach into Italian-American media and business influence.
During the trial of Sacco and Vanzetti, Tresca organized publicity, fundraising, and the defense lawyer Fred Moore. In the 1930s, Tresca became an outspoken opponent of Soviet Communism and Stalinism, particularly after the Soviet Union had engineered the destruction of the anarchist movement in Catalonia and Aragon during the Spanish Revolution of 1936. In 1937, Tresca was a member of the Dewey Commission, which cleared Leon Trotsky of all charges made during the Moscow Trials. In early 1938, Tresca publicly accused the Soviets of kidnapping Juliet Stuart Poyntz to prevent her defection from the Communist Party USA underground apparatus. Tresca alleged that before she had disappeared, Poyntz had talked to him about "exposing the communist movement".
Assassination On January 11, 1943, in New York City, Tresca was leaving his parole officer's offices when he dodged surveilling officers by jumping into a car that was waiting for him. Two hours later, Tresca was crossing Fifth Avenue at 15th Street on foot when a black Ford pulled up beside him.
Vito Genovese, the boss of the Genovese crime family, is said to have allegedly ordered the murder of Tresca, with the shooter allegedly being Carmine Galante of the Bonanno crime family. No one was ever charged in the Tresca murder. A eulogy at his memorial service was delivered by Angelica Balabanoff, a socialist activist and former Bolshevik. According to Lewis Coser's account of the funeral, "I was sitting near a burly Irish policeman who clearly didn't understand a word of Balabanoff's fierce Italian oratory. But at her climax he burst into tears."
