Born Cassius Clay in Louisville, Kentucky, in 1942, Muhammad Ali became an Olympic gold medalist in 1960 and the world heavyweight boxing champion in 1964. Following his suspension for refusing military service, Ali reclaimed the heavyweight title two more times during the 1970s, winning famed bouts against Joe Frazier and George Foreman along the way. Diagnosed with Parkinson’s disease in 1984, Ali devoted much of his time to philanthropy, earning the Presidential Medal of Freedom in 2005. He died on June 3, 2016, in Phoenix, Arizona.
Boxer, philanthropist and social activist Muhammad Ali was born Cassius Marcellus Clay Jr. on January 17, 1942, in Louisville, Kentucky. Ali showed at an early age that he wasn’t afraid of any bout—inside or outside of the ring. Growing up in the segregated South, he experienced racial prejudice and discrimination firsthand.
At the age of 12, Ali discovered his talent for boxing through an odd twist of fate. His bike was stolen, and Ali told a police officer, Joe Martin, that he wanted to beat up the thief. “Well, you better learn how to fight before you start challenging people,” Martin reportedly told him at the time. In addition to being a police officer, Martin also trained young boxers at a local gym.
Ali started working with Martin to learn how to spar, and soon began his boxing career. In his first amateur bout in 1954, he won the fight by split decision. Ali went on to win the 1956 Golden Gloves tournament for novices in the light heavyweight class. Three years later, he won the National Golden Gloves Tournament of Champions, as well as the Amateur Athletic Union’s national title for the light heavyweight division.
After his Olympic victory, Ali was heralded as an American hero. He soon turned professional with the backing of the Louisville Sponsoring Group, and continued overwhelming all opponents in the ring. Ali took out British heavyweight champion Henry Cooper in 1963, and then knocked out Sonny Liston in 1964 to become the heavyweight champion of the world.
Often referring to himself as “the greatest,” Ali was not afraid to sing his own praises. He was known for boasting about his skills before a fight and for his colorful descriptions and phrases. In one of his more famously quoted descriptions, Ali told reporters that he could “float like a butterfly, sting like a bee” in the boxing ring.
Conversion to Islam and Suspension
This bold public persona belied what was happening in Ali’s personal life, however. He was doing some spiritual searching and decided to join the black Muslim group the Nation of Islam in 1964. At first he called himself “Cassius X” before settling on the name Muhammad Ali. (The boxer eventually converted to orthodox Islam during the 1970s.)
Ali later started a different kind of fight with his outspoken views against the Vietnam War. Drafted into the military in April 1967, he refused to serve on the grounds that he was a practicing Muslim minister with religious beliefs that prevented him from fighting. He was arrested for committing a felony and almost immediately stripped of his world title and boxing license.
The U.S. Department of Justice pursued a legal case against Ali, denying his claim for conscientious objector status. He was found guilty of violating Selective Service laws and sentenced to five years in prison in June 1967, but remained free while appealing his conviction. Unable to compete professionally in the meantime, Ali missed more than three prime years of his athletic career. The U.S. Supreme Court eventually overturned the conviction in June 1971.
Prior to the Supreme Court’s decision, Ali returned to the ring in 1970 with a win over Jerry Quarry. The following year, Ali took on Joe Frazier in what has been called the “Fight of the Century.” Frazier and Ali went toe-to-toe for 14 rounds before Frazier dropped Ali with a vicious left hook in the 15th. Ali recovered quickly, but the judges awarded the decision to Frazier, handing Ali his first professional loss after 31 wins. Ali soon suffered a second loss, to Ken Norton, but he beat Frazier in a 1974 rematch.
Another legendary Ali fight, against undefeated heavyweight champion George Foreman, took place in 1974. Billed as the “Rumble in the Jungle,” the bout was organized by promoter Don King and held in Kinshasa, Zaire. For once, Ali was seen as the underdog to the younger, massive Foreman, but he silenced his critics with a masterful performance. He baited Foreman into throwing wild punches with his “rope-a-dope” technique, before stunning his opponent with an eighth-round knockout to reclaim the heavyweight title.
Ali and Frazier locked horns for their grudge match in Quezon City, Philippines, in 1975. Dubbed the “Thrilla in Manila,” the bout nearly went the distance, with both men delivering and absorbing tremendous punishment. However, Frazier’s trainer threw in the towel after the 14th round, giving the hard-fought victory to Ali.
After losing his title to Leon Spinks in February 1978, Ali defeated him in a September rematch, becoming the first boxer to win the heavyweight championship three times. Following a brief retirement, he returned to the ring to face Larry Holmes in 1980, but was overmatched against the younger champion. Following one final loss in 1981, to Trevor Berbick, the boxing great retired from the sport.
Philanthropy and Diagnosis of Parkinson’s
In his retirement, Ali devoted much of his time to philanthropy. He announced that he had Parkinson’s disease in 1984, a degenerative neurological condition, and was involved in raising funds for the Muhammad Ali Parkinson Center in Phoenix, Arizona. Over the years, Ali also supported the Special Olympics and the Make-A-Wish Foundation, among other organizations.
Ali traveled to numerous countries, including Mexico and Morocco, to help out those in need. In 1998, he was chosen to be a United Nations Messenger of Peace because of his work in developing nations.
In 2005, Ali received the Presidential Medal of Freedom from President George W. Bush. He also opened the Muhammad Ali Center in his hometown of Louisville, Kentucky, that same year. “I am an ordinary man who worked hard to develop the talent I was given,” he said. “Many fans wanted to build a museum to acknowledge my achievements. I wanted more than a building to house my memorabilia. I wanted a place that would inspire people to be the best that they could be at whatever they chose to do, and to encourage them to be respectful of one another.”
Despite the progression of his disease, Ali remained active in public life. He was on hand to celebrate the inauguration of the first African-American president in January 2009, when Barack Obama was sworn into office. Soon after the inauguration, Ali received the President’s Award from the NAACP for his public service efforts.
Ali was survived by his fourth wife, Yolanda, whom he had been married to since 1986. The couple had one son, Asaad, and Ali had several children from previous relationships, including daughter Laila Ali, who followed in his footsteps by becoming a champion boxer.
Universally regarded as one of the greatest boxers in history, Ali’s stature as a legend continued to grow even as his physical state diminished. He continues to be celebrated not only for his remarkable athletic skills but for his willingness to speak his mind and his courage to challenge the status quo.
