Alcide Patrick Nunez, also known as Yellow Nunez and Al Nunez, was an influential American jazz clarinetist born on March 17, 1884, in St. Bernard Parish, Louisiana. He was of Isleño and French Creole descent. Growing up in New Orleans, Nunez became a prominent figure in the jazz scene, known for his skill on the clarinet and his ability to improvise.

Nunez began his musical career around 1902, initially playing guitar before switching to the clarinet. By 1905, he was a regular performer with Papa Jack Laine's band and played with other notable musicians such as Tom Brown. In 1916, Nunez moved to Chicago with Stein's Dixie Jass Band, which later became the Original Dixieland Jass Band. However, he left the band before their first recordings.

In 1917, Nunez was involved in a legal dispute over the copyright of "Livery Stable Blues," a hit recorded by the Original Dixieland Jass Band. He and cornet player Ray Lopez had filed for copyright before Nick LaRocca and the band, leading to a lawsuit that was eventually dismissed.

After his time in Chicago, Nunez moved to New York City, where he played with Bert Kelly's band and later formed the Louisiana Five with drummer Anton Lada. The band became popular in New York, recording for several labels. Nunez continued to perform until 1927, when he returned to New Orleans. Despite losing his teeth, he regained his ability to play the clarinet with dentures and joined the New Orleans Police Band.

Nunez was married three times and had four children. He passed away from a heart attack on September 2, 1934, in New Orleans. His legacy as a pioneering jazz clarinetist and his influence on musicians like Pee Wee Russell remain significant in the history of jazz.
