Ethel Kennedy, the wife of Sen. Robert F. Kennedy, died on Thursday. She was 96.

Kennedy had been hospitalized after suffering a stroke in her sleep on Oct. 3, her family confirmed to The Associated Press.

“It is with our hearts full of love that we announce the passing of our amazing grandmother,” Joe Kennedy III posted on X. “She died this morning from complications related to a stroke suffered last week.”

She raised 11 children after Robert F. Kennedy was assassinated.

“Along with a lifetime’s work in social justice and human rights, our mother leaves behind nine children, 34 grandchildren and 24 great-great grandchildren along with numerous nieces and nephews, all of whom love her dearly,” the family statement said, per The AP.

The human rights advocate became a widow in 1968, at the age of 40, when her husband, then-presidential candidate Robert F. Kennedy, was assassinated in California after winning the state’s Democratic primary. She never remarried.

Kennedy founded the Robert F. Kennedy Center for Justice and Human Rights. She was awarded in 2014 the Presidential Medal of Freedom by President Barack Obama.
