Before he became chief counsel for the NAACP, U.S. solicitor general, and the first African-American Supreme Court justice, Thurgood Marshall was a fledgling young lawyer who struggled to begin a law practice in his hometown of Baltimore during the depths of the Great Depression. In his new book, Larry S. Gibson, a Baltimore attorney and law professor, tells the story of Marshall’s first 28 years before he moved to New York in 1936 to work in the NAACP’s national office.
