He received a B.A. from Allen University in 1931, working as a laborer and running a dry cleaning business to pay for his education. DeLaine worked with Modjeska Simkins and the South Carolina NAACP on the case Briggs v. Elliott, which challenged segregation in Summerton, South Carolina. DeLaine also memorably taught school in South Carolina, and in 2006 was inducted into South Carolina's Educational Hall of Honor at the University of South Carolina.
