The actress died Sunday night at her Connecticut home, her publicist Rick Miramontez said. She was treated for breast cancer in 2003.
"Our beloved mother Lynn Rachel passed away peacefully after a seven-year journey with breast cancer," Redgrave's children — Ben, Pema and Annabel — said in a statement Monday. "She lived, loved and worked harder than ever before. The endless memories she created as a mother, grandmother, writer, actor and friend will sustain us for the rest of our lives."
Born in London, Redgrave was a member of the illustrious Redgrave family of actors. She was the youngest child of Michael Redgrave and Rachel Kempson. Her older siblings were Vanessa Redgrave and Corin Redgrave, who died early last month at 70. The actress was also the aunt to Joely Richardson, Carlo Gabriel Nero, Jemma Redgrave and Natasha Richardson, who died last year from head injuries sustained in a skiing accident.
Redgrave received Oscar nominations for Georgy Girl and God and Monsters, as well as Tony nominations for Mrs. Warren's Profession, Shakespeare for My Father and The Constant Wife. She also appeared in TV shows including Ugly Betty, Law & Order and Desperate Housewives in recent years.
In interviews, the actress — who was married more than 30 years to actor-director John Clark until they divorced in 2000 — acknowledged that she suffered from bulimia in the past and became the spokeswoman for Weight Watchers. She also published a book with daughter Annabel Clark in 2004, Journal: A Mother and Daughter's Recovery From Breast Cancer.
Redgrave is survived by her three children, six grandchildren, sister Vanessa, and four nieces and nephews.
