Muhammad Ali, who stole the hearts of boxing fans during the 60s and 70s, has died at age 74.

The three-time Heavyweight champion was hospitalized on Thursday for a respiratory issue.

Parkinson’s disease plagued Ali’s health for over 30 years.

Ali was born Cassius Clay in Louisville, Kentucky before he ultimately became Muhammad Ali after joining the Nation of Islam. He became heavyweight champion in 1964 after knocking out Sonny Liston.

Ali’s daughter, Laila, took to Facebook to post a throwback photo of her father with her daughter Sydney just hours before his passing.

The post read, “I love this photo of my father and my daughter Sydney when she was a baby! Thank for all the love and well wishes. I feel your love and appreciate it!!”
