Given the question: Generate a question that has the following answer: Doll for the following movie plot: When criminal mastermind Erwin "Doc" Riedenschneider (Sam Jaffe) is released from prison after seven years, he immediately goes to see a bookie named Cobby (Marc Lawrence) in an unnamed Midwest river city (almost certainly Cincinnati), who arranges a meeting with Alonzo Emmerich (Louis Calhern), a high-profile lawyer. Emmerich listens with interest to Doc's plan to steal jewelry worth a million dollars or more. Doc needs $50,000 to hire three mena "box man" (safecracker), a driver, and a "hooligan"to help him pull off the caper, to "operate", in the criminal jargon used in the film, and each man could be called an "operator", although this term was not used in the film. Emmerich agrees to provide the money to "operate", and then suggests that he, himself (not one or more fences) assume the responsibility for disposing of the loot. Doc first hires Louie Ciavelli (Anthony Caruso), a professional safecracker. Ciavelli only trusts Gus Minissi (James Whitmore), a hunchbacked diner owner, as the getaway driver. The final member of the gang is Dix Handley (Sterling Hayden), a friend of Gus. Dix explains his ultimate goal to Doll Conovan (Jean Hagen), who is in love with him. His dream is to buy back the horse farm that his father lost during the Great Depression. Dix, however, just keeps losing his ill-gotten gains betting on the horses via Cobby. This job would pay him the amount he needs. During the meticulously planned crime (an 11-minute sequence in the film), the criminals carry out their work in a calm, professional manner. Ciavelli hammers through a brick wall to get into the jewelry store, deactivates a door alarm to let in Doc and Dix, and then opens the main safe in minutes using home-brewed nitroglycerine ("the soup"). Unfortunately, the explosion somehow sets off the alarms of nearby businesses and brings the police to the scene more quickly than expected. On their way out, Dix has to slug an arriving security guard, who drops his revolver, which discharges and wounds Ciavelli in the belly. The men...
The answer is:
Who was the criminal mastermind?
