Mary Wilson, one of the founding members of The Supremes passed away Monday, at age 76.

Wilson lived in the same housing complex as Diana Ross, Florence Ballard, and Betty McGlown. They came together first as The Primettes. The group became The Supremes and signed with Motown records in 1961, eventually becoming a trio of Ross, Ballard, and Wilson. The group went on to have 12 #1 hits.

In the 2000’s Wilson went back to college and earned an Associate Degree. She also became a leading advocate for the Truth in Music Advertising Act, which is now law in 35 states. The act mandates that a group cannot use a famous name (like The Supremes) unless there is at least one original member performing.

In a statement, Barry Gordy said: “…Mary Wilson was extremely special to me. She was a trailblazer, a diva and will be deeply missed.”
