The 40th stamp in the Black Heritage series honors Dorothy Height (1912-2010), a D.C. activist who dedicated her life to fighting for racial and gender equality. The unveiling took place at Cramton Auditorium on the campus of Howard University on Feb. 1.  Considered one of the most influential civil rights leaders of the 20th century, the United States Postal Service unveiling included Rep. John Lewis (D-Ga.); Alexis Herman, White House assistant to the President; Omorosa Manigault, director of communications for the Office of Public Liaison; and Dr. Ben Carson, United States Secretary of Housing and Urban Development.
