On Oct. 11, 1918, Baltimore health commissioner Dr. John Blake ordered all churches and poolrooms closed, and hinted that saloons might have to close as well. The next day, Blake ordered dentists to wear gauze masks while with patients, and limited the operating hours of saloons and bars to 9:30 am to 4:30 pm.
