Answer by taking a quote from the following article:

Louis Thomas Jordan (July 8, 1908 - February 4, 1975) was a pioneering American musician, songwriter and bandleader who was popular from the late 1930s to the early 1950s. Known as "The King of the Jukebox", he was highly popular with both black and white audiences in the later years of the swing era. Jordan was one of the most successful African-American musicians of the 20th century, ranking fifth in the list of the most successful black recording artists according to Joel Whitburn's analysis of Billboard magazine's R&B chart. Though comprehensive sales figures are not available, he had at least four million-selling hits during his career.

Jordan was born on July 8, 1908, in Brinkley, Arkansas, where his father, James Aaron Jordan, was a music teacher and bandleader for the Brinkley Brass Band and for the Rabbit Foot Minstrels. His mother, Adell, died when Louis was young. Jordan studied music under his father, starting out on the clarinet. In his youth he played in his father's bands instead of doing farm work when school closed. He also played the piano professionally early in his career, but alto saxophone became his main instrument. However, he became even better known as a songwriter, entertainer and vocalist. Jordan briefly attended Arkansas Baptist College, in Little Rock, and majored in music. After a period with the Rabbit Foot Minstrels (in which one of his colleagues was Leon "Pee Wee" Whittaker) and with local bands, including Bob Alexander's Harmony Kings, he went to Philadelphia and then New York. In 1932, Jordan began performing with the Clarence Williams band, and when he was in Philadelphia he played clarinet in the Charlie Gaines band. In late 1936 he was invited to join the influential Savoy Ballroom orchestra, led by the drummer Chick Webb. Based at New York's Savoy Ballroom, Webb's orchestra was renowned as one of the best big bands of its day and regularly beat all comers at the Savoy's legendary cutting contests. Jordan worked with Webb until 1938, and it proved a vital stepping-stone in his career--Webb (who was physically disabled) was a fine musician but not a great showman. The ebullient Jordan often introduced songs as he began singing lead; he later recalled that many in the audience took him to be the band's leader, which undoubtedly boosted his confidence further. This was the same period when the young Ella Fitzgerald was coming to prominence as the Webb band's lead female vocalist; she and Jordan often sang duets on stage, and they later reprised their partnership on several records, by which time both were major stars. In 1938, Webb fired Jordan for trying to persuade Fitzgerald and others to join his new band. By this time Webb was already seriously ill with tuberculosis of the spine. He died at the age of 34, after spinal surgery on June 16, 1939. Following his death, Fitzgerald took over the band.
