Irene Lipscomb is something of a local bridge between an older generation of African-Americans who grew up in the days of segregation, and today’s millennial youth who are engaged in the fight for social and economic justice. A member of the Newtown Florist Club, a Gainesville civil rights organization established in 1950, Lipscomb chaired this year’s Martin Luther King Jr. holiday committee, helping to organize a day full of sermons, marches and community discussions that aim to carry King’s message and activism forward.
