After the Civil War, the Southwest Waterfront became a neighborhood for the poorer classes of Washingtonians. The neighborhood was divided in half by Fourth Street SW, then known as 4 Street; Scotch, Irish, German, and eastern European immigrants lived west of 4 Street, while freed blacks lived to the east. Each half was centered on religious establishments: St. Dominic's Catholic Church and Talmud Torah Congregation on the west, and Friendship Baptist Church on the east. (Also, each half of the neighborhood was the childhood home of a future American musical star — the first home of Al Jolson, whose father was the cantor of Talmud Torah Congregation, after his family emigrated from what is now Lithuania was on 4 Street, and Marvin Gaye was born in a tenement on First Street.)
