Former First Lady Nancy Reagan has died. Mrs. Reagan passed away at the age of 94 of congestive heart failure, according to a spokesperson at the Reagan Library.

She died at her home in Bel-Air, California

A former actress, Nancy Davis married fellow actor Ronald Reagan on March 4, 1952.

Her marriage to Ronald Reagan lasted 52 years until his death in 2004.

She was Reagan's closest adviser and fierce protector on his journey from actor to governor of California to president of the United States.

She rushed to his side after he was shot in 1981 by a would-be assassin, and later endured his nearly decade-long battle with Alzheimer's disease. In recent years she broke with fellow Republicans in backing stem cell research as a way to possibly find a cure for Alzheimer's.
