Actress Natasha Richardson has died in hospital in New York after suffering a head injury in a skiing accident in Canada.
Her husband, the actor Liam Neeson, and their two sons, aged 13 and 12, were at her bedside.
Aged 45, she was the daughter of actress Vanessa Redgrave and director Tony Richardson.
She fell on a beginners' slope at the Mont Tremblant resort in Quebec last Monday, and collapsed some time later.
Ms Richardson fell ill after what initially appeared to be a meaningless tumble during a beginner's ski lesson.
But her condition worsened and she was eventually taken to hospital in Ste-Agathe and then flown to New York and rushed to intensive care.
Born in May 1963, Natasha Richardson was educated in London and trained at the Central School of Speech and Drama in the city.
She made her film debut at age four in 'The Charge of the Light Brigade,' a movie her father directed.
Her considerable stage experience includes a number of Shakespearean roles, including Ophelia in Hamlet and Helena in A Midsummer Night's Dream.
In 1986 she won the London Drama Critics' most promising newcomer award for her performance as Nina in 'The Seagull' alongside her mother.
Ms Richardson went on to win the Tony award for best actress in a musical for her performance as Sally Bowles in Cabaret, directed by future Oscar-winner Sam Mendes.
On the big screen, Ms Richardson played opposite an 11-year-old Lindsay Lohan in the 1998 film The Parent Trap, and appeared in Maid In Manhattan with Jennifer Lopez in 2002.
Her sister is Joely Richardson, a star of the US TV series Nip/Tuck.
Her death has revived a debate about the use of safety helmets for skiing.
