Did Gregory Hines (the dancer) participate in any important charities in his life time?

Answer 1

Depends on what you mean by "important." It turns out that Gregory Hines was very involved in cause-oriented activities, even establishing his own foundation.

According to a Rutgers University newsletter,

"Shortly before his death, Hines won two NCAA Image Awards for his work on the TV docudrama Bojangles in 2001.

Hines - who will posthumously be named a Doctor of the Fine Arts by the University - also became renowned locally for his work in the arts in New Brunswick and at Rutgers. In addition to serving as the nationally honorary chairperson of the American Repertory Ballet's DancePower program, he also performed three separate benefit concerts at the State Theatre for dance education in the New Brunswick Public School District.

In 1999, he established the Gregory Hines DancePower Endowed Scholarship at Rutgers, a fund designed to assist New Brunswick High School graduates who were also DancePower members to attend the University."

In addition, "The dancer and actor, Gregory Hines, was telling me there were so many homeless people in his Manhattan neighborhood that he felt compelled to come here for the next day's "Housing Now!" march on the Mall. (Washington DC)National Review, Nov. 10, 1989
