Nicola Sacco and Bartolmeo Vanzetti, Italian anarchists, were executed unjustly in 1927 for armed robbery and murder of two pay-clerks in Massachusetts. The case caused quite a stir at the time as for many the conviction was not for murder, but for being anarchists and immigrants. They were pardoned in 1977 by Governor Michael Dukakis. In 1947, twenty years after the execution, my father commissioned an album of original songs penned and sung by Woody Guthrie about the trial, an album Woody himself believed was his most important work.
