Character actress Ann B. Davis earned superstar status in the pantheon of television domestic help with her portrayal of Alice, housekeeper to “The Brady Bunch” (ABC, 1969-1974). A comedy veteran and two-time Emmy winner for “The Bob Cummings Show” (NBC/CBS, 1955-59), Davis frequently stole her scenes from the younger cast and brought a dose of polish and professionalism to the series’ juvenile scripts. Post-“Brady,” Davis was a pitchwoman for Minute Rice and guest star on various TV comedies, but eventually retreated from the public eye to devote her time to religious pursuits.Born Ann
