Montgomery is perhaps best remembered for her leading role as the witch Samantha in the ABC sitcom Bewitched.
Ms. Montgomery refused to do Samantha's famous nose twitch for fans after Bewitched went off the air. She spent the remainder of her career pursuing dramatic roles that took her as far away from the Samantha typecast as possible.
She died in 1995 eight weeks after being diagnosed with colon cancer and was cremated.
She had an older sister, Martha Bryan Montgomery.
