The music icon — who is known for many hit songs including "Boogie Wonderland," "September" and "Let's Groove" — sadly passed away after a long battle with Parkinson's disease. He was diagnosed in 1992 and stopped touring with the band two years later due to his illness.
Maurice is survived by his two brothers and fellow band members, Verdine, 64, and Fred, 61.
