Brenda Fricker, who became the first Irish woman to win an Academy Award for her role as Bridget Fagan Brown in the 1989 film “My Left Foot,’’ has died. She was 81. Her agent, Phil Belfield, says the Irish character actor died Thursday night in Dublin after a period of ill health. Fricker became the first Irish woman to win an Academy Award in 1990 for best supporting actress for her portrayal of the determined mother of Christy Brown, who was born with cerebral palsy and could control only his left foot. Daniel Day-Lewis, who played Christy Brown, won the award for best actor.
