LOUISVILLE, Ky. — Muhammad Ali's fists made him famous, but his plight as a social activist was perhaps his biggest fight.
The Muhammad Ali Center in his hometown of Louisville is seen as a lasting legacy to the three-time world heavyweight champion.
Exhibits show Ali railing against war, segregation and poverty. Visitors also see the softer side of a man embracing ideals of respect and spiritual growth.
On Saturday, the 6-year-old center will be in the limelight when Ali is surrounded by friends for a private party celebrating his 70th birthday. The party will double as a $1,000-per-person fundraiser for Ali's beloved center.
Ali, who is battling Parkinson's disease, turns 70 on Tuesday.
