Legend
One of the most famous cases in our 100-year history celebrates an anniversary today: On July 22, 1934, the gangster John Dillinger was killed in Chicago, moments after leaving the Biograph Theater, where, ironically, he had watched a gangster film starring Clark Gable.
In the Depression years of the early 1930s, Dillinger’s bank robberies, shootouts, and jailbreaks earned him nationwide notoriety, but to the Bureau, he was just Public Enemy #1. And after months of pursuing him, a tip led Melvin Purvis, Special Agent in Charge of our Chicago office, to the Biograph on a hot Sunday night.
The day before, Purvis and Special Agent Samuel A. Cowley, who had been appointed by Director J. Edgar Hoover to head the Dillinger investigation, had met with a woman calling herself Anna Sage, a friend of Dillinger’s girlfriend, Polly Hamilton. She was hoping that her cooperation with the authorities would earn her reward money and keep her from being deported to her native Romania. She told Purvis that Dillinger planned to take both her and Hamilton to a Sunday evening movie at the Biograph or the Marbro.
Stakeouts were arranged for both theaters. A hand-written document from our Dillinger file, a diagram of the Biograph, illustrates the placement of some 20 men around the theater and across the street. The diagram shows the letters “A,” “B,” and “C” outside the theater box office, with an “X” next to each letter. A legend identifies the significance of the letters: “Dillinger companion,” “Dillinger,” “informant."
The informant—Anna Sage—called Purvis at 8:30 p.m. that Sunday to say they were going to the Biograph. Two hours later, Dillinger emerged from the theater with his two companions. Purvis, standing nearby, lit a cigar. It was the signal for his men to move in. As they did, Dillinger realized what was happening and reached for his pistol. Agents fired, and Dillinger was hit. He staggered, then fell.
