Madison was also a civil rights activist known for staging protests and acts of civil disobedience, and a key figure in the top circles of African American leadership and activism. A native of Dayton, Ohio, he graduated from Washington University in St. Louis, which awarded him an honorary doctorate in 2019. In that same year he was also elected to the National Radio Hall of Fame in recognition of over 40 years in broadcasting. His signature line when people called his show to speak about injustice was “What are you going to do about it?”

Madison is survived by his wife, Sherry; his children Jason, Monesha, Shawna and Michelle; his five grandchildren; and one great-grandchild.
