Holmes "Daddy-O" Daylie (May 15, 1920 – February 6, 2003) was a pioneering radio personality known for his influential role in black-appeal radio during the 1940s and 1950s. Born in Covington, Tennessee, Daylie faced early personal challenges, losing his mother at birth and his father five years later. Raised by his older brother, Clinton, the family moved to Chicago's South Side, where Daylie attended John D. Shoop Elementary and Morgan Park High School, excelling in basketball.

After a brief stint with the Harlem Globetrotters, Daylie returned to Chicago, where his charismatic bartending style caught the attention of disc jockey Dave Garroway. Encouraged by Garroway, Daylie transitioned to radio, debuting "Daddy-O's Jazz Patio" on WAIT in 1948. Known for his rhythmic monologues and deep jazz knowledge, he became a beloved figure on stations like WMAQ, WAAF, and WGN.

Daylie's career was marked by his commitment to civil rights, notably through initiatives like Operation Christmas Basket, which provided food to needy Chicagoans. His influence extended to musicians such as the Ramsey Lewis Trio, whom he helped gain recognition. Inducted into the Black Radio Hall of Fame in 1990, Daylie retired in 1988 and passed away in 2003, leaving a lasting legacy in the world of jazz and radio.
