William Thomas "Champion Jack" Dupree (July 23, 1909 or July 4, 1910 – January 21, 1992) was an American blues and boogie-woogie pianist and singer. His nickname was derived from his early career as a boxer.
Dupree was a New Orleans blues and boogie-woogie pianist,
a barrel-house "professor". His father was from the Belgian Congo and
his mother was part African American and Cherokee. His birth date has been
given as July 4, July 10, and July 23, 1908, 1909, or
1910; the researchers Bob
Eagle and Eric LeBlanc give July 4, 1910. He was orphaned at the age of eight
and was sent to the Colored Waifs Home in New Orleans, an institution for
orphaned or delinquent boys (about the same time, Louis Armstrong was also sent
there as a child, after being arrested as a "dangerous and suspicious
character"). Dupree taught himself to play the piano there and later
apprenticed with Tuts Washington and Willie Hall, whom he called his father and
from whom he learned "Junker's Blues". He was also a "spy
boy" for the Yellow Pocahontas tribe of the Mardi Gras Indians. He soon
began playing in barrel-houses and other drinking establishments.

He began a life of travelling, living in Chicago, where
he worked with Georgia Tom, and in Indianapolis, Indiana, where he met Scrapper
Blackwell and Leroy Carr. He also worked as a cook. In Detroit, after Joe Louis
encouraged him to become a boxer, he fought 107 bouts, winning Golden Gloves
and other championships and picking up the nickname Champion Jack, which he
used the rest of his life.
In 1940, Dupree made his recording debut for Chicago
A&R man extraordinaire Lester Melrose and OKeh Records.
Many of Dupree's songs were later credited to Melrose as
composer, and Melrose claimed publishing rights to them.
Dupree's 1940-1941 output for the Columbia subsidiary
exhibited
a strong New Orleans tinge despite the Chicago surroundings; his
driving "Junker's Blues" was later cleaned up as Fats Domino's 1949
debut, "The Fat Man." Dupree's career was interrupted by military
service in World War II. He was a cook in the United States Navy and was held
by the Japanese for two years as a prisoner of war. Following Franklin D.
Roosevelt's death in office, Dupree composed the "F.D.R. Blues".

After World War II Dupree decided tickling the 88s beat
pugilism any old day. He spent most of his time in New York and quickly became
a prolific recording artist, cutting for Continental, Joe Davis, Alert, Apollo,
and Red Robin (where he cut a blasting "Shim Sham Shimmy" in 1953),
often in the company of Brownie McGhee. King Records corralled Dupree in 1953
and held onto him through 1955 (the year he enjoyed his only R&B chart hit,
the relaxed "Walking the Blues.") Dupree's King output rates with his
very best; the romping "Mail Order Woman," "Let the Doorbell
Ring," and "Big Leg Emma's" contrasting with the rural "Me
and My Mule". Contracts meant little; Dupree masqueraded as Brother Blues
on Abbey, Lightnin' Jr. on Empire, and the truly imaginative Meat Head Johnson
for Gotham and Apex.
His biggest commercial success was "Walkin' the
Blues", which he recorded as a duet with Teddy McRae. This led to several
national tours and eventually a European tour. In 1959, he played an unofficial
(and unpaid) duo gig with Alexis Korner at the London School of Economics.

In the 1970s and 1980s, he lived at Ovenden in Halifax,
England, after marrying a Halifax native, Shirley Ann Harrison, whom he met in
London. A piano he used was later discovered at Calderdale College in Halifax.
He continued to record in Europe with the Kenn Lending Band, Louisiana Red and
Axel Zwingenberger and made many live appearances. He also worked again as a
cook, specializing in New Orleans cuisine. He returned to the United States from
time to time and performed at the New Orleans Jazz & Heritage Festival.

Perhaps sensing his own mortality, Dupree returned to New
Orleans in 1990 for his first visit in 36 years. While there, he played the
Jazz & Heritage Festival and laid down a zesty album for Bullseye Blues,
Back Home in New Orleans.
