US Tests Female Mail Carriers in Cities
In the midst of World War I, a major change quietly began in the United States Postal Service: for the first time, women were seriously tested as city letter carriers. On November 23, 1917, First Assistant Postmaster General John C. Koons issued a call to the postmasters of eight of the largest US post offices to run 15-day trials of women serving as letter carriers in the city. This experiment was described as a potential wartime necessity, because many men were off fighting, and extra postal workers were already needed to handle the heavy Christmas mail in December.
