ABSTRACT The Centre Avenue YMCA was a “colored” YMCA formed under the separate but equal doctrine, but its separate status did more than maintain segregation. Pittsburgh’s Centre Avenue YMCA was chief among the businesses, schools, and institutions established and led by African Americans, for African Americans, in the first half of the twentieth century. It shielded its members from the racism of White-controlled spaces, provided facilities and programs previously unavailable to Pittsburgh’s African American community, and nurtured leadership and activism toward greater equality and civil rights. Its upper floors provided hotel-like rooms to African American visitors, workers, and students denied entrance to mainstream accommodations. Its significance is embodied in its 1923 building, the only one still standing in Pennsylvania to have been partially funded by philanthropist Julius Rosenwald in an initiative to construct African American YMCAs nationwide; Pittsburgh’s African American community raised the required matching funds.
