Not a Robot - A Fire Eater (1937)
This photo ran in the October 29, 1937 Chester Times (Chester, PA).
The firefighter of the future is shown making his bow at a demonstration in the Philadelphia Navy Yard. Garbed in an asbestos suit, this smoke eater walks undaunted into the flames, armed with a chemical pump which quickly subdues flames. The equipment is to be used on airplane carriers.
