According to Wikipedia,
William Henry "Chick" Webb was an American jazz and swing music drummer and band leader. Early life Webb was born in Baltimore, Maryland, to William H. and Marie Webb. The year of his birth is disputed. The Encyclopædia Britannica and Allmusic indicate 1905, and this seems to be supported by census information. Other publications claim other years. During Webb's lifetime, a December 1937 DownBeat magazine article, "The Rise of a Crippled Genius", stated he was born in 1909, which is the year that appears on his grave marker. In 1939, The New York Times stated that Webb was born in 1907, the year also suggested in Rhythm on Record by Hilton Schleman.
