Approximately 77,000 postal employees are African-American. USPS will commemorate the month through activities at its facilities, as well as through the dedication of the Dorothy Height stamp, the 40th entry in the Black Heritage series.
African-American History Month traces its roots to 1926, when historian Carter G. Woodson spearheaded a weeklong commemoration to raise awareness of African-Americans’ contributions to the nation’s history and culture.
The annual observance was expanded to a full month in 1976.
