Arnold Alois Schwarzenegger (; German: [ˈaɐ̯nɔlt ˈalɔʏs ˈʃvaɐ̯tsn̩ˌɛɡɐ]; born July 30, 1947) is an Austrian-American actor, producer, businessman, investor, author, philanthropist, activist, politician, and former professional bodybuilder. He served two terms as the 38th Governor of California from 2003 to 2011. Schwarzenegger began weight training at the age of 15. He won the Mr. Universe title at age 20 and went on to win the Mr. Olympia contest seven times, remaining a prominent presence in bodybuilding and writing many books and articles on the sport. He is widely considered to be arguably the greatest bodybuilders of all time as well as that sport's most charismatic ambassador. Schwarzenegger gained worldwide fame as a Hollywood action-film icon. His breakthrough film was the sword-and-sorcery epic Conan the Barbarian in 1982, a box-office hit that resulted in a sequel. In 1984, he appeared in the title role of James Cameron's critically and commercially successful science-fiction thriller film The Terminator. He subsequently reprised the Terminator character in the franchise's later installments: Terminator 2: Judgment Day (1991), Terminator 3: Rise of the Machines (2003), and Terminator Genisys (2015). He has appeared in a number of successful films, such as Commando (1985), The Running Man (1987), Predator (1987), Twins (1988), Total Recall (1990), Kindergarten Cop (1990), and True Lies (1994). As a Republican, Schwarzenegger was first elected on October 7, 2003, in a special recall election to replace then-Governor Gray Davis. He was sworn in on November 17, to serve the remainder of Davis' term. He was then re-elected in the 2006 California gubernatorial election, to serve a full term as governor. In 2011, he completed his second term as governor and returned to acting. Schwarzenegger was nicknamed "the Austrian Oak" in his bodybuilding days, "Arnie" during his acting career, and "The Governator" (a portmanteau of "Governor" and "Terminator") during his political career.
