Schwarzenegger served in the Austrian Army in 1965 to fulfill the one year of service required at the time of all 18-year-old Austrian males. During his army service, he won the Junior Mr. Europe contest. He went AWOL during basic training so he could take part in the competition and then spent a week in military prison: "Participating in the competition meant so much to me that I didn't carefully think through the consequences." He entered another bodybuilding contest in Graz, at Steirerhof Hotel, where he placed second. He was voted "best-built man of Europe", which made him famous in bodybuilding circles. "The Mr. Universe title was my ticket to America—the land of opportunity, where I could become a star and get rich." Schwarzenegger made his first plane trip in 1966, attending the NABBA Mr. Universe competition in London. He would come in second in the Mr. Universe competition, not having the muscle definition of American winner Chester Yorton.Charles "Wag" Bennett, one of the judges at the 1966 competition, was impressed with Schwarzenegger and he offered to coach him. As Schwarzenegger had little money, Bennett invited him to stay in his crowded family home above one of his two gyms in Forest Gate, London. Yorton's leg definition had been judged superior, and Schwarzenegger, under a training program devised by Bennett, concentrated on improving the muscle definition and power in his legs. Staying in the East End of London helped Schwarzenegger improve his rudimentary grasp of the English language. Living with the Bennetts also changed him as a person: "Being with them made me so much more sophisticated. When you're the age I was then, you're always looking for approval, for love, for attention and also for guidance. At the time, I wasn't really aware of that. But now, looking back, I see that the Bennett family fulfilled all those needs. Especially my need to be the best in the world. To be recognized and to feel unique and special. They saw that I needed that care and attention and love."Also in 1966, while at Bennett's home, Schwarzenegger had the opportunity to meet childhood idol Reg Park, who became his friend and mentor. The training paid off and, in 1967, Schwarzenegger won the title for the first time, becoming the youngest ever Mr. Universe at the age of 20. He would go on to win the title a further three times. Schwarzenegger then flew back to Munich, where he attended a business school and worked in a health club (Rolf Putziger's gym, where he worked and trained from 1966 to 1968), returning in 1968 to London to win his next Mr. Universe title. He frequently told Roger C. Field, his English coach and friend in Munich at that time, "I'm going to become the greatest actor!"Schwarzenegger, who dreamed of moving to the U.S. since the age of 10, and saw bodybuilding as the avenue through which to do so, realized his dream by moving to the United States in October 1968 at the age of 21, speaking little English. There he trained at Gold's Gym in Venice, Los Angeles, California, under Joe Weider's supervision. From 1970 to 1974, one of Schwarzenegger's weight training partners was Ric Drasin, a professional wrestler who designed the original Gold's Gym logo in 1973. Schwarzenegger also became good friends with professional wrestler Superstar Billy Graham. In 1970, at age 23, he captured his first Mr. Olympia title in New York, and would go on to win the title a total of seven times.The immigration law firm Siskind & Susser has stated that Schwarzenegger may have been an illegal immigrant at some point in the late 1960s or early 1970s because of violations in the terms of his visa. LA Weekly would later say in 2002 that Schwarzenegger is the most famous immigrant in America, who "overcame a thick Austrian accent and transcended the unlikely background of bodybuilding to become the biggest movie star in the world in the 1990s".In 1977, Schwarzenegger's autobiography/weight-training guide Arnold: The Education of a Body
