Natasha Richardson

Natasha Richardson's organs have been donated at the request of her family, according to People.

"[Organ donation] is very Natasha," a family friend told the magazine. "She spent so much time fighting the stigma of AIDS; someone like that would naturally donate her organs. At least by donating her organs something good could come out of [the tragedy]."

The philanthropic Richardson had been on the board of trustees of the amFAR foundation for AIDS research since 2006. She became a champion for the cause after her father, Oscar-winning director Tony Richardson, died of complications from the disease in 1991.

Richardson, 45, died March 18 of blunt trauma to the brain after a skiing accident in Montreal. She was buried Sunday at a cemetery near her Millbrook, NY home, which she shared with her husband, Liam Neeson, and their sons, Micheal, 13, and Daniel, 12.

"Liam is doing okay," said family friend Blaine Trump. "It takes a while to absorb this. But he says the family needs to move forward. They will take it one step at a time."

Micheal and Daniel have gone back to school and Neeson is expected to return to the Toronto set of Chloe soon. "With good friends by their side, they will get through the tough days ahead," Trump said.
