The Story

William Lewis was a Philadelphia lawyer and judge whose convictions helped end slavery in his state at the dawn of the republic. He played a key role in drafting and passing Pennsylvania's 1780 Act for the Gradual Abolition of Slavery — the first such law in America — and spent his life defending the freedom it granted, serving as counsel for the Pennsylvania Abolition Society. His elegant summer home, Strawberry Mansion, built in 1789, still stands as a reminder of the man.

Why it matters

His work made Pennsylvania a pioneer of legislated emancipation, launching the slow legal campaign against slavery that would define the nation for the next century.

Jefferson Street Ballparks

Philadelphia, PA · est. 2017

On these North Philadelphia grounds, active from 1864 to 1891, Americans watched baseball grow up. In 1869 the Black activist and educator Octavius Catto led his Pythian club against the white Olympics in what is remembered as the first interracial baseball game, a quiet act of defiance in a segregated city. Seven years later the site hosted the first National League game, marking the sport's leap from amateur pastime to organized professional business.

Church of the Advocate

Philadelphia, PA · est. 1999

Built between 1887 and 1897 as a soaring Gothic Revival church, the Church of the Advocate became a spiritual and political anchor for North Philadelphia's growing African American community after 1930. It hosted major Black Power gatherings in the 1960s and '70s, and in 1974 it made history as the site where the first eleven women were ordained Episcopal priests.

Ed Bradley (1941-2006)

Philadelphia, PA · est. 2021

Ed Bradley grew up in Philadelphia and got his start in broadcasting at WDAS radio not far from this spot before rising to the top of American journalism. He reported from the battlefields of Vietnam and Cambodia, became the first African American television correspondent to cover the White House, and spent 26 years as a fixture on CBS's 60 Minutes. Along the way he collected 19 Emmys, a Peabody, and a lifetime achievement award from the National Association of Black Journalists.

Opportunities Industrialization Centers

Philadelphia, PA · est. 1990

In 1964, in the unlikely setting of an abandoned Philadelphia jailhouse, Rev. Leon H. Sullivan opened the first Opportunities Industrialization Center to train Black workers for skilled jobs that discrimination had long kept beyond their reach. Born of the same organizing energy as Sullivan's earlier 'selective patronage' boycotts, O.I.C. paired vocational instruction with dignity and self-reliance, and the model spread from this city to hundreds of centers across the nation and eventually overseas.
