The Bureau of Prisons personnel arrived on Alcatraz in early February; among them was Loring O. Mills, acting chief clerk. In April 1934, the old material was removed from the prison, holes were cut in the concrete and 269 cell fronts were installed, built using four carloads of steel ordered from the Stewart Iron Works. A legend at the works is that a shipment of cells and iron accidentally fell into San Francisco Bay during transportation from San Francisco Dock to Alcatraz
Alcatraz Federal Penitentiary Prisons. The purpose of this transfer was to punish those involved in the rampant crime which prevailed in the country in the 1920s and 1930s. The United States Disciplinary Barracks on Alcatraz was acquired by the United States Department of Justice on October 12, 1933, and the island became a Federal Bureau of Prisons federal prison in August 1934. The $260,000 conversion to the federal prison took place from January 1934. George Hess of the United States Public Health Service was appointed the chief medical officer of the prison and Edward W.
