input: Dixon left Mississippi for Chicago in 1936. A man of considerable stature, standing 6 and a half feet tall and weighing over 250 pounds, he took up boxing, at which he was successful, winning the Illinois State Golden Gloves Heavyweight Championship (Novice Division) in 1937. He became a professional boxer and worked briefly as Joe Louis's sparring partner, but after four fights he left boxing in a dispute with his manager over money.  Dixon met Leonard Caston at a boxing gym, where they would harmonize at times. Dixon performed in several vocal groups in Chicago, but it was Caston that persuaded him to pursue music seriously. Caston built him his first bass, made of a tin can and one string. Dixon's experience singing bass made the instrument familiar. He also learned to play the guitar.  In 1939, Dixon was a founding member of the Five Breezes, with Caston, Joe Bell, Gene Gilmore and Willie Hawthorne. The group blended blues, jazz, and vocal harmonies, in the mode of the Ink Spots. Dixon's progress on the upright bass came to an abrupt halt with the advent of World War II, when he refused induction into military service as a conscientious objector and was imprisoned for ten months. He refused to go to war because he would not fight for a nation in which institutionalized racism and racist laws were prevalent. After the war, he formed a group named the Four Jumps of Jive. He then reunited with Caston, forming the Big Three Trio, which went on to record for Columbia Records.

input: Tjader soon quit Shearing after a gig at the San Francisco jazz club the Blackhawk. In April 1954, he formed the Cal Tjader Modern Mambo Quintet. The members were brothers Manuel and Carlos Duran on piano and bass respectively, Bayardo "Benny" Velarde on timbales, bongos, and congas, and Edgard Rosales on congas (Luis Miranda replaced Rosales after the first year). Back in San Francisco and recording for Fantasy Records, the group produced several albums in rapid succession, including Mambo with Tjader.  The Mambo craze reached its pitch in the late 1950s, a boon to Tjader's career. Unlike the exotica of Martin Denny and Les Baxter, music billed as "impressions of" Oceania (and other locales), Tjader's bands featured seasoned Cuban players and top-notch jazz talent conversant in both idioms. He cut several notable straight-ahead jazz albums for Fantasy using various group names, most notably the Cal Tjader Quartet (composed of bassist Gene Wright, drummer Al Torre, and pianist Vince Guaraldi). Tjader is sometimes lumped in as part of the West Coast (or "cool") jazz sound, although his rhythms and tempos (both Latin and bebop) had little in common with the work of Los Angeles jazzmen Gerry Mulligan, Chet Baker, or Art Pepper.  Tjader and his band opened the second Monterey Jazz Festival in 1959 with an acclaimed "preview" concert. The first festival had suffered financially. Tjader is credited with bringing in big ticket sales for the second and saving the landmark festival before it had even really started. The Modern Mambo Quintet disbanded within a couple of years. Tjader formed several more small-combo bands, playing regularly at such San Francisco jazz clubs as the Blackhawk.

input: Cassius Marcellus Clay Jr. () was born on January 17, 1942, in Louisville, Kentucky. He had a sister and four brothers. He was named for his father, Cassius Marcellus Clay Sr. (1912-1990), who himself was named in honor of the 19th-century Republican politician and staunch abolitionist, Cassius Marcellus Clay, also from the state of Kentucky. Clay's father's paternal grandparents were John Clay and Sallie Anne Clay; Clay's sister Eva claimed that Sallie was a native of Madagascar. He was a descendant of slaves of the antebellum South, and was predominantly of African descent, with smaller amounts of Irish and English heritage. His father painted billboards and signs, and his mother, Odessa O'Grady Clay (1917-1994), was a domestic helper. Although Cassius Sr. was a Methodist, he allowed Odessa to bring up both Cassius Jr. and his younger brother Rudolph "Rudy" Clay (later renamed Rahman Ali) as Baptists. Cassius Jr. attended Central High School in Louisville.  Clay grew up amid racial segregation. His mother recalled one occasion when he was denied a drink of water at a store--"They wouldn't give him one because of his color. That really affected him." He was also affected by the 1955 murder of Emmett Till, which led to young Clay and a friend's taking out their frustration by vandalizing a local railyard.  Clay was first directed toward boxing by Louisville police officer and boxing coach Joe E. Martin, who encountered the 12-year-old fuming over a thief's having taken his bicycle. He told the officer he was going to "whup" the thief. The officer told Clay he had better learn how to box first. Initially, Clay did not take up Martin's offer, but after seeing amateur boxers on a local television boxing program called Tomorrow's Champions, Clay was interested in the prospect of fighting. He then began to work with trainer Fred Stoner, whom he credits with giving him the "real training", eventually moulding "my style, my stamina and my system". For the last four years of Clay's amateur career he was trained by boxing cutman Chuck Bodak.  Clay made his amateur boxing debut in 1954 against local amateur boxer Ronnie O'Keefe. He won by split decision. He went on to win six Kentucky Golden Gloves titles, two national Golden Gloves titles, an Amateur Athletic Union national title, and the Light Heavyweight gold medal in the 1960 Summer Olympics in Rome. Clay's amateur record was 100 wins with five losses. Ali said in his 1975 autobiography that shortly after his return from the Rome Olympics, he threw his gold medal into the Ohio River after he and a friend were refused service at a "whites-only" restaurant and fought with a white gang. The story was later disputed, and several of Ali's friends, including Bundini Brown and photographer Howard Bingham, denied it. Brown told Sports Illustrated writer Mark Kram, "Honkies sure bought into that one!" Thomas Hauser's biography of Ali stated that Ali was refused service at the diner but that he lost his medal a year after he won it. Ali received a replacement medal at a basketball intermission during the 1996 Olympics in Atlanta, where he lit the torch to start the games.
