Euday Louis Bowman (November 9, 1886 – May 26, 1949) was an influential American composer and pianist, best known for his contributions to the ragtime genre. Born in Fort Worth, Texas, Bowman was the son of George A. Bowman and Marguerite Olivia Estee Landin. Raised in a musically inclined family, his mother and sister were both piano teachers, which likely influenced his early exposure to music.

Bowman is most celebrated for composing "Twelfth Street Rag," a piece that became a staple in the jazz and ragtime repertoire. The composition, published in 1914, was inspired by his time playing piano in the bordellos of Kansas City and was named after a street in Fort Worth's red-light district. Despite its success, Bowman initially sold the rights to the song for a mere $100 and missed out on significant royalties until he regained the copyright years later.

Throughout his career, Bowman composed several other pieces, including "Sixth Street Rag," "Tenth Street Rag," "Eleventh Street Rag," "Fort Worth Blues," and "Kansas City Blues." His work was performed and recorded by numerous prominent artists, such as Louis Armstrong, Duke Ellington, and Pee Wee Hunt, contributing to the enduring popularity of ragtime music.

Bowman's life was marked by personal challenges, including a brief marriage to Geneva Morris and a later marriage in 1949 that ended shortly after. Despite these difficulties, he remained a celebrated figure in the ragtime community, performing in various venues and promoting his music.

Euday Bowman passed away in New York City in 1949, leaving behind a legacy as a pivotal figure in American ragtime music. His compositions, particularly "Twelfth Street Rag," continue to be celebrated for their influence on the development of jazz and popular music.
