William John Clifton "Bill" Haley (July 6, 1925 – February 9, 1981) was one of the first American rock and roll musicians. He is credited by many with first popularizing this form of music in the early 1950s with his group Bill Haley & His Comets (inspired by Halley's Comet) and their hit song "Rock Around the Clock".
Bill Haley was born in Highland Park, Michigan as William John Clifton Haley. Because of the effects of the Great Depression on the Detroit area, his father moved the family to Boothwyn, Pennsylvania, near the town of Chester, when Bill was seven years old. Haley's father William Albert Haley was from Kentucky and played the banjo and mandolin, his mother Maude Green originally from Ulverston in England was a technically accomplished keyboardist with classical training. Haley told the story that when he made a simulated guitar out of cardboard, his parents bought him a real one.
