The Postal Service and other organizations will observe Women’s History Month, which begins March 1.
Women have shaped postal history since 1775, when Mary Katherine Goddard was appointed the first woman postmaster in Baltimore.
The first known appointment of a woman to carry mail occurred in 1845, when Sarah Black began ferrying mail between the Charlestown, MD, Post Office and a nearby train depot.
Other trailblazers include Polly Martin, who drove a mail wagon in Massachusetts from 1860-1876, becoming the first woman known to carry mail on a contract route, and Katherine Stinson, who became the first woman pilot to carry mail in 1913.
The first known women to serve as city carriers were Permelia Campbell and Nellie McGrath, who began delivering mail to customers in Washington, DC, in 1917.
Megan J. Brennan became the first woman to serve as Postmaster General last year.
