This video from The American Mercury’s centennial series highlights the significant role of prosecutor Frank Arthur Hooper in the 1913 Leo Frank trial for the murder of 13-year-old Mary Phagan at the National Pencil Company in Atlanta. Drawing from the Leo Frank Trial Brief of Evidence, it focuses on Hooper’s closing arguments on August 21, 1913, where he addressed the jury, emphasizing the pursuit of truth and justice. Hooper portrayed Frank as a “Dr. Jekyll” figure, suggesting a dual nature that hid predatory behavior toward young female employees like Phagan, supported by forensic evidence such as her blood and hair found in the factory. The episode examines Hooper’s low-key yet powerful delivery, which complemented lead prosecutor Hugh Dorsey’s efforts, leading to Frank’s conviction.
