S.L. Harrison, a late professor of Communication at the University of Miami, wrote that Duffy “displayed uncommon vigor in attacking the Ku Klux Klan”. Scopes Trial Just a year after Duffy began working for The Baltimore Sun, 1925, a famous trial began in Tennessee. Tennessee had passed a law, the Butler Act, barring teachers against the topic of evolution in the classroom, but one biology teacher, John T. Scopes, ignored the law and taught his students evolution. Scopes decided that the students should learn evolution, even if it went against the teachings of the bible. Since the trial was popular and a nationwide topic, Mencken took a staff from The Sun, including Duffy, to cover the trial. “[Edmund Duffy’s] graphic artwork played a significant role in the public’s perception of the trial proceedings reported in the pages of The Sun, then one of America’s most influential newspapers”. His cartoons brought more attention to the issue, as he derided Tennessee for crushing knowledge in one of his more notable cartoons from the trial called ‘A Closed Book in Tennessee.’ In this cartoon, Duffy shows a man, representing Tennessee, holding a sign that says “Fundamentalists Only Wanted as Teachers.” The man is standing on top of the book of knowledge, holding it shut. Duffy knew that this powerful cartoon would cause a great response, but that is exactly what Mencken wanted and expected from him. Many more of his cartoons from the trial held the same message, in which he was publicly shaming Tennessee for the law, the trial, and the verdict. Mencken once said that with a good cartoonist he would not need a whole editorial staff, and a great cartoonist he found in Duffy. Pulitzer Prizes Over Edmund Duffy's career, he won three Pulitzer Prizes, which is a lot compared to other recipients over the years. His three prize winning cartoons are the following: “An Old Struggle Still Going On” (1931) This cartoon references the anti-communism era that began in the 1920s and 1930s. At the time, communism was seen as being anti-religion, which is what Duffy conveys in the cartoon. “California Points with Pride!” (1934) This cartoon is one of Duffy's many anti-lynching pieces. This one, however, deals with white on white lynching. In California, people took two kidnappers from prison and lynched them in a park, but the Governor praised the people that did the lynching. Duffy condemned
