William Henry Joseph Bonaparte Bertholoff Smith (November 25, 1897– April 18, 1973), also known as “The Lion“, was an American jazzpianist and one of the masters of the stride style, usually grouped with James P. Johnson and Thomas “Fats” Waller as the three greatest practitioners of the genre in its golden age, from about 1920 to 1943.

William Henry Joseph Bonaparte Bertholoff was born in Goshen, New York. His mother and grandmother chose the names to reflect the different parts of his heritage: Joseph after Saint Joseph (Bible), Bonaparte (French), Bertholoff (biological father’s last name), Smith (added when he was three, his stepfather’s name), and William and Henry which were added for “spiritual balance”.

In his memoir he reports that his father, Frank Bertholoff, was Jewish. Willie was at least somewhat conversant in Yiddish, as he demonstrated in a television interview late in his life. Willie’s mother, Ida Oliver, had “Spanish, Negro, and Mohawk Indian blood”. Her mother, Ann Oliver, was a banjo player and had been in Primrose and West minstrel shows (Smith also had two cousins who were dancers in the shows, Etta and John Bloom).
