She was just 18 years old

But she knew the history of the African-American freedom struggle from relatives among the Brotherhood of Sleeping Car Porters and the Tuskegee Airmen.  Tamam Tracy Moncur (then Tracy Sims) did not flinch from the call of history when she commanded 2,000 demonstrators to fill the stately Palace Hotel in San Francisco.

Black American Day highlights the centrality of the black experience to American history beginning with the death of Crispus Attucks on March 5, 1770 at the hands of British soldiers in the Boston Massacre.

ReUNION: Education-Arts-Heritage produced a documentary "Who Was Tracy Sims?" that gives the personal insights of one of the most important leaders of the 1960s, who disappeared from public view for almost 50 years.

On Black American Day, a tour of the African-American Freedom Trail traces the footsteps of those civil rights pioneers.
