Recognized throughout much of his career as "the world's greatest living entertainer," Sammy Davis, Jr. was a remarkably popular and versatile performer equally adept at acting, singing, dancing, and impersonations -- in short, a variety artist in the classic tradition. A member of the famed Rat Pack, he was among the very first African-American talents to find favor with audiences on both sides of the color barrier, and remains a perennial icon of cool. Born in Harlem on December 8, 1925, Davis made his stage debut at the age of three performing with Holiday in Dixieland, a black vaudeville troupe featuring his father and helmed by his de facto uncle, Will Mastin; dubbed "Silent Sam, the Dancing Midget," he proved phenomenally popular with audiences and the act was soon renamed Will Mastin's Gang Featuring Little Sammy. At the age of seven, Davis made his film debut in the legendary musical short Rufus Jones for President, and later received tap-dancing lessons courtesy of the great Bill "Bojangles" Robinson. In 1941, the Mastin Gang opened for Tommy Dorsey at Detroit's Michigan Theater; there Davis first met Dorsey vocalist Frank Sinatra -- the beginning of a lifelong friendship.
