Clarice Taylor — the actress and comedian best known for playing Anna Huxtable, the grandmother on “The Cosby Show” — has died at the age of 93. Taylor died earlier this week of congestive heart failure, according to an obituary in the L.A. Times. During the run of “The Cosby Show,” Taylor played Anna Huxtable, doting grandmother to the Huxtable children and no-nonsense mother to Bill Cosby’s Heathcliff Huxtable.
