Gardner Jackson seems to meet the criteria for notability given his acknowledged role as a leading advocate in the Sacco Vanzetti case, his participation in the New Deal, and his record as a social and labor activist. The large body of cited works by notable journalists such as Murray Kepmton, and historians such as Arthur Schlesinger, Jr., as well as Jackson's collected letters and papers stored at the FDR Library justify his inclusion as a historical figure who played a role in several significant events of the early 20th century.
