IN: Jens Ingemar Johansson (Swedish: ['ING:emar 2ju:hans,son]; 22 September 1932 - 30 January 2009) was a Swedish professional boxer who competed from 1952 to 1963. He held the world heavyweight title from 1959 to 1960, and was the fifth heavyweight champion born outside the United States. Johansson won the title by defeating Floyd Patterson via third-round stoppage, after flooring him seven times in that round. For this achievement, Johansson was awarded the Hickok Belt as top professional athlete of the year--the only non-American to do so in the belt's entire 27-year existence--and was named the Associated Press Male Athlete of the Year and Sports Illustrated Sportsman of the Year.

Johansson's introduction to the top rank of the sport was inauspicious. At age nineteen he was disqualified for passivity at the Helsinki 1952 Summer Olympics in the heavyweight competition in a fight against eventual Olympic gold medalist Ed Sanders. Johansson maintained he was not evading Sanders (who also got a warning for passivity), but rather was trying to tire his opponent. Johansson said he had been limited to a 10-day training camp, had only trained with newcomers, and had been told by his coach to let Sanders be the aggressor. Nevertheless, his silver medal was withheld for poor performance and only presented to him in 1982. Johansson had earned his spot in the Olympics by winning the Swedish National Championship earlier the same year, 1952, after he knocked out his opponent in the first round of the final. After the Olympics Johansson went into seclusion for six months and considered quitting boxing. However, he returned to the ring and turned professional under the guidance of the Swedish publisher and boxing promoter Edwin Ahlquist, subsequently winning his first 21 professional fights. He won the Scandinavian pro title by knocking down and outscoring the Dane Erik Jensen (breaking his right hand in the process). A broken hand and a one-year military service kept him out of the ring until late 1954. In August 1955, in his twelfth professional fight, Johansson knocked out former European Heavyweight Champion Hein ten Hoff in the first round. He took the Scandinavian heavyweight title in 1953 and, on 30 September 1956, he won the European Heavyweight Championship by scoring a 13th-round KO over Italy's Franco Cavicchi in Milan for the European title. Johansson successfully defended his European Crown against ranked heavyweights Henry Cooper (fifth-round KO on 19 May 1957) and Joe Erskine, with a TKO in 13 on 21 February 1958.

Did he win anything at the Olympics or was completely disqualified?

OUT: his silver medal was withheld for poor performance and only presented to him in 1982.

input: Ali said that he first heard of the Nation of Islam when he was fighting in the Golden Gloves tournament in Chicago in 1959, and attended his first Nation of Islam meeting in 1961. He continued to attend meetings, although keeping his involvement hidden from the public. In 1962, Clay met Malcolm X, who soon became his spiritual and political mentor. By the time of the first Liston fight, Nation of Islam members, including Malcolm X, were visible in his entourage. This led to a story in The Miami Herald just before the fight disclosing that Clay had joined the Nation of Islam, which nearly caused the bout to be canceled. In fact, Clay was initially refused entry to the Nation of Islam (often called the Black Muslims at the time) due to his boxing career. However, after he won the championship from Liston in 1964, the Nation of Islam was more receptive and agreed to publicize his membership. Shortly afterwards on March 6, Elijah Muhammad gave a radio address that Clay would be renamed Muhammad (one who is worthy of praise) Ali (most high). Around that time Ali moved to the south side of Chicago and lived in a series of houses, always near the Nation of Islam's Mosque Maryam or Elijah Muhammad's residence. He stayed in Chicago for about 12 years. Only a few journalists (most notably Howard Cosell) accepted the new name at that time. Ali later announced: "Cassius Clay is my slave name." Not afraid to antagonize the white establishment, Ali stated, "I am America. I am the part you won't recognize. But get used to me. Black, confident, cocky; my name, not yours; my religion, not yours; my goals, my own; get used to me." Ali's friendship with Malcolm X ended as Malcolm split with the Nation of Islam a couple of weeks after Ali joined, and Ali remained with the Nation of Islam. Ali later said that turning his back on Malcolm was one of the mistakes he regretted most in his life. Aligning himself with the Nation of Islam, its leader Elijah Muhammad, and a narrative that labeled the white race as the perpetrator of genocide against African Americans made Ali a target of public condemnation. The Nation of Islam was widely viewed by whites and some African Americans as a black separatist "hate religion" with a propensity toward violence; Ali had few qualms about using his influential voice to speak Nation of Islam doctrine. In a press conference articulating his opposition to the Vietnam War, Ali stated, "My enemy is the white people, not Viet Cong or Chinese or Japanese." In relation to integration, he said: "We who follow the teachings of Elijah Muhammad don't want to be forced to integrate. Integration is wrong. We don't want to live with the white man; that's all". Writer Jerry Izenberg once noted that, "the Nation became Ali's family and Elijah Muhammad became his father. But there is an irony to the fact that while the Nation branded white people as devils, Ali had more white colleagues than most African American people did at that time in America, and continued to have them throughout his career."

Answer this question "Why did he hide his involvement?"
output:
In fact, Clay was initially refused entry to the Nation of Islam (often called the Black Muslims at the time) due to his boxing career.
