James Edwards "Jimmy" Yancey (February 20, 1894 – September 17, 1951) was an African American boogie-woogie pianist, composer, and lyricist. One reviewer noted him as "one of the pioneers of this raucous, rapid-fire, eight-to-the-bar piano style".
Yancey was born in Chicago in (depending on the source) 1894, or 1898. His older brother, Alonzo Yancey (1894 – 1944) was also a pianist, while their father was a guitarist. Yancey started performing as a singer in traveling shows during his childhood. He was a noted pianist by 1915, and influenced younger musicians, such as Meade Lux Lewis and Albert Ammons.Source: Wikipedia
