THE CASE OF SACCO AND VANZETTI
One of the most sensational murder trials in United States history took place in Massachusetts in 1921. Although the defendants were convicted and later executed, the results of the trial aroused worldwide protests. On April 15, 1920, during a payroll robbery at a shoe company in South Braintree, Massachusetts, the company paymaster, F.A. Parmenter, and the guard, Alessandro Berardelli, were shot to death. On May 5, two Italian immigrants, Nicola Sacco and Bartolomeo Vanzetti were arrested and charged with the crime. The fact that both were armed at the time made them prime suspects. In addition, both were known to not only have dodged the draft in World War One, but also for being political radicals and anarchists. A storm of protest arose. A committee headed by A. Lawrence Lowell, president of Harvard University, issued a report in August 1927 stating that the trial had been fair. With the issuance of the report and with Governor AT Fuller's refusal to grant clemency, protests increased. Benito Mussolini, premier of Italy, made a special plea for their lives. Demonstrations were held in major cities. Bombs were set off in New York City and Philadelphia. All the protest was to no avail as Sacco and Vanzetti were both executed by electrocution on August 23, 1927.
In the 1970s however, Vincent Teresa, a former member of the Mafia, declared in his autobiography that Sacco and Vanzetti had not been involved in the South Braintree killings. He said the actual guilty parties were members of a gang of Italian-American criminals. The case has strongly affected many artists. American composer Marc Blitzstein was working on his major opera "Sacco and Vanzetti" at the time of his death. The artist Ben Shahn's first major success was with his 23 satirical paintings based on the trial and execution of Sacco and Vanzetti, which were exhibited in New York City in 1933, and these brought him instant acclaim.
