Paul Whiteman was an American bandleader and orchestral director, often referred to as the "King of Jazz." Born on March 28, 1890, in Denver, Colorado, he played a significant role in popularizing jazz music in the 1920s. Whiteman's orchestra was known for its unique blend of jazz and classical music, and he was instrumental in bringing jazz to mainstream audiences. Whiteman is perhaps best known for commissioning the famous composer George Gershwin to write the orchestral piece Rhapsody in Blue, which premiered in 1924. His innovative approach to music helped bridge the gap between jazz and popular music, influencing many musicians and paving the way for future genres.
