Charles Bronson was an American actor. He was known for his roles in action films and his "granite features and brawny physique". Bronson was born into extreme poverty in Ehrenfeld, Pennsylvania, a coal mining town in Pennsylvania's Allegheny Mountains. Bronson's father, a miner, died when Bronson was young. Bronson himself worked in the mines as well until joining the United States Army Air Forces in 1943 to fight in World War II. After his service, he joined a theatrical troupe and studied acting. During the 1950s, he played various supporting roles in motion pictures and television, including anthology drama TV series in which he would appear as the main character. Near the end of the decade, he had his first cinematic leading role in Machine-Gun Kelly (1958).
