Bill Robinson, nicknamed Bojangles (born Luther Robinson; May 25, 1878 – November 25, 1949), was an American tap dancer, actor, and singer, the best known and the most highly paid African-American entertainer in the United States during the first half of the 20th century. His long career mirrored changes in American entertainment tastes and technology. His career began in the age of minstrel shows and moved to vaudeville, Broadway theatre, the recording industry, Hollywood films, radio, and television. According to dance critic Marshall Stearns, "Robinson's contribution to tap dance is exact and specific. He brought it on its toes, dancing upright and swinging," adding a "hitherto-unknown lightness and presence." His signature routine was the stair dance, in which he would tap up and down a set of stairs in a rhythmically complex sequence of steps, a routine that he unsuccessfully attempted to patent. He is also credited with having popularized the word copacetic through his repeated use of it in vaudeville and radio appearances. He is famous for his dancing with Shirley Temple in a series of films during the 1930s, and for starring in the musical Stormy Weather (1943), loosely based on his own life and selected for preservation in the National Film Registry. He used his popularity to challenge and overcome numerous racial barriers. Robinson was one of the first minstrel and vaudeville performers to appear as Black without the use of blackface makeup, as well as one of the earliest black performers to perform solo, overcoming vaudeville's two-colored rule. Additionally, he was an early black headliner in Broadway shows. Robinson was the first black performer to appear in a Hollywood film in an interracial dance team (with Shirley Temple in The Little Colonel, 1935), and the first black performer to headline a mixed-race Broadway production. Robinson came under heavy criticism for his apparent tacit acceptance of racial stereotypes of the era, with some critics calling him an Uncle Tom. He strongly resented this, and his biographers suggested that critics were underestimating the difficulties faced by black performers engaging with mainstream white culture at the time, and ignoring his many efforts to overcome racial prejudice. In his public life, Robinson led efforts to persuade the Dallas Police Department to hire its first black policeman; lobby President Franklin Delano Roosevelt during World War II for equal treatment of black soldiers; and stage the first integrated public event in Miami,
