John Llewellyn Lewis

John Llewellyn Lewis was an American leader of organized labor who served as the ninth president of the United Mine Workers of America (UMW) from 1920 to 1960 and the first president of the Congress of Industrial Organizations (CIO), which organized millions of industrial workers during the Great Depression, from 1935 to 1940. Lewis was a major figure in the history of coal mining and the American labor movement; his supporters credited him with high wages, pensions, and medical benefits in the mining industry. Throughout his career in the public eye, Lewis was frequently caricatured and came to represent the broader American labor movement.
