Language of Materials



The personal papers and library of the former Pennsylvania State Supreme Court justice, congressman, and author Michael A. Musmanno are located in the University Archives at Duquesne University. Documents include papers from Musmanno’s time as a defense attorney in the Sacco & Vanzetti trial, judge in the Nuremburg Trials, witness in the case against Adolf Eichmann, and interviews with Hitler’s associates. The collection also covers papers related to campaigns to end the Sunday Blue Laws, illegalize the Communist Party and to disband the Coal and Iron Police. This particular collection is an extension of these holdings, containing the papers from Judge Musmanno and John Mullen during the trial in the 1950s in which Musmanno was accused of hindering a witness in another trial. John Mullen was the Mayor of Clairton, Pennsylvania, a suburb of Pittsburgh with a large industrial workforce. John Mullen and Musmanno were good friends for many years as they worked together to support unions. Musmanno was also an important figure in the fight against Communism throughout South Western Pennsylvania and the United States. In 1953 Mullen accused Musmanno of hindering a witness in another trial that Mullen was involved in. Musmanno had to stand trial for the accusations, the case was eventually dismissed. However, the Senate Task Force of the Internal Security Subcommittee was investigating subversive actives in Pittsburgh and decided to further investigate the Mullen Case. During these hearings it was discovered that the Communist group in Pittsburgh had used the Mullen Case as a way to frame Musmanno and stop his work against them. Mullen was charged as being a communist during these hearings, but these charges were eventually dropped, although significant evidence was found to prove that the Mullen case was an effort to frame and harass Musmanno. This collection contains some of the trial transcripts from the early sessions of the trial in Pennsylvania as well as the Senate Task Force hearings. The Mullen Case led to an extensive collection of news articles and opinions in news articles regarding Musmanno, Mullen, and the Communists. The largest portion of the collection includes the information from the Senate Committee Hearings. Many people wrote to Musmanno in support of his efforts against Communism and against Mullen
