Billy Bitzer filmed 21 short actualities inside the Pittsburgh Westinghouse Works in April and May of 1904. Audiences of the day would have been treated to footage of factory panoramas, women winding armatures and turbines being assembled. These industrial films were produced for the American Mutoscope & Biograph Company.
