David E. Crawford opened Eureka Co-Operative Bank in Boston in 1910, 'the only bank in the East owned and operated by ‘Colored People.'' He was appointed a master in the Chancery by the Governor of Massachusetts in 1915, and in 1916 the citizens of Boston elected him as a delegate to the National Republican Convention in Chicago. By 1920 his holdings of apartments, stores, and commercial properties were valued at $150,000.
