Joe Madison, also known as "The Black Eagle," has died at the age of 74. The radio legend, who was inducted into the Radio Hall of Fame in 2019, began his career at Detroit's WXYZ in 1980 and later worked at stations in Philadelphia and Washington, popularising his show through syndication on the Radio One Talk Network. In 2015, he achieved a Guinness World Record for the longest on-air broadcast, at 52 hours, raising $250,000 for the Smithsonian National Museum of African American History and Culture. He also held the record for the longest consecutive broadcast by a radio personality. Outside of his broadcasting career, Madison also served as the national political director of the NAACP and was a prominent activist for the civil rights movement.
