LOUISVILLE, Ky. (AP) โ€” For years after boxing great Cassius Clay adopted the Muslim faith and changed his name, his hometown paper refused to call him Muhammad Ali.

Fifty years later, The Courier-Journal, Louisvilleโ€™s daily paper, apologized for continuing to call him Cassius Clay after he changed it in 1964. It did not consistently refer to him as Muhammad Ali until 1970.

Ali died June 3 and an estimated 100,000 people lined the streets of Louisville to say goodbye to the cityโ€™s most celebrated son during his funeral Friday.

Executive Editor Neil Budde wrote Mondayโ€™s editorial that chronicled how the paper for years either ignored Aliโ€™s preferred name or outright mocked it.

โ€œWe wonโ€™t even try to speculate what the motives of the editors in that era were,โ€ he wrote. โ€œThe CJ was certainly an early champion of civil rights and desegregation. Yet we took what in todayโ€™s light is an oddly hostile approach on the specific issue of Aliโ€™s name, which did little to help race relations in a turbulent time.

The paper was among many newspapers and magazines across the country that continued to call him Cassius Clay for years after he changed his name in keeping with his Islamic faith.

Budde said reporter Joe Gerth researched the newspaperโ€™s history and editors debated the proper way to address it after Aliโ€™s death, as a series of planned memorials and spontaneous celebrations consumed the city for a week. The editors decided to issue a belated apology.

He compared it to the Lexington Herald-Leaderโ€™s front-page clarification in 2004, in which the paper apologized for having failed 40 years earlier to properly cover the civil rights movement.
