Al Jolson was a Lithuanian-born American singer, actor, and vaudevillian.
He was one of the United States' most famous and highest-paid stars of the 1920s, and was self-billed as "The World's Greatest Entertainer". Jolson was known for his "shamelessly sentimental, melodramatic approach" towards performing, as well as for popularizing many of the songs he sang. Jolson has been referred to by modern critics as "the king of blackface performers".
Although best remembered today as the star of the first talking picture, The Jazz Singer, he starred in a series of successful musical films during the 1930s. After the attack on Pearl Harbor in December 1941, he was the first star to entertain troops overseas during World War II. After a period of inactivity, his stardom returned with The Jolson Story, in which Larry Parks played the younger Jolson, but with sung vocals dubbed by Jolson himself. The formula was repeated in a sequel, Jolson Sings Again. In 1950, he again became the first star to entertain GIs on active service in the Korean War, performing 42 shows in 16 days. He died weeks after returning to the U.S., partly owing to the physical exhaustion from the performance schedule.
