Hines has been in many spotlights during her three decades as a professional actress, most famously for her role as Larry David’s wife on “Curb Your Enthusiasm.” She cut her teeth in the Groundlings, a Los Angeles-based improv troupe; “Curb” is outlined but unscripted Hines was raised in Tallahassee, Florida and she and Mr. Kennedy wed in 2014. After cosmetology school and the University of Central Florida, her first acting job was at Universal Studios, where she performed the shower scene from “Psycho” up to 15 times a day for a live audience. Hines was still paying her dues: bartending, working as the personal assistant to the filmmaker and actor Rob Reiner and going to improv classes when her break came in 1999, when she was cast in “Curb Your Enthusiasm.” She and Kennedy met in 2006 when Larry David, a longtime friend of Mr. Kennedy’s, introduced them at a ski-weekend fund-raiser in Banff, Canada, for Waterkeeper Alliance, an environmental nonprofit co-founded by Kennedy. Hines was well entrenched in her own philanthropic work: for the nonprofit United Cerebral Palsy, after her nephew was diagnosed, and for under-resourced schools. In May of 2012, Mr. Kennedy’s second wife, Mary Richardson Kennedy, died by suicide at her home in Bedford, N.Y. Hines and Kennedy got married two years later.
