Arnold Miller

Arnold Ray Miller (April 25, 1923 – July 12, 1985) was a miner and labor activist who served as president of the United Mine Workers of America (UMWA), AFL–CIO, from 1972 to 1979. Winning as a reform candidate, he gained positive changes for the miners, including compensation for black lung disease. He had difficulty dealing with growing internal union opposition. His last two years as president were particularly tumultuous and he suffered two heart attacks, finally resigning in November 1979 with the title of "president emeritus for life".
