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 vaudeville guitarist and singer. By age ten, Yancey had toured across the United States as a tap dancer and singer, and by twenty he had toured throughout Europe. He began teaching himself piano at 15, and by 1915 had become a noted pianist and was already influencing younger musicians, including Meade Lux Lewis and Albert Ammons.Source: Wikipedia
