The veteran actress, the only surviving board member from the first days of guild in the 1930s, was handed the Ralph Morgan Award for service during a presentation in Los Angeles on Saturday (19Jun10).
Introduced by her Titanic castmate Frances Fisher, Stuart, who will turn 100 on 4 July (10), whispered to the crowd: "I'm very, very grateful. I've had a wonderful life of giving and sharing."
Also receiving the Ralph Morgan Award at the ceremony was longtime SAG board member, actor Paul Napier, who paid tribute to Stuart during his own acceptance speech, adding: "What an honour it is to be sharing billing with the legend, Gloria Stuart."
The actress is best known in recent years for her role as Old Rose in James Cameron's 1997 blockbuster. A video tribute to the star also included her roles in 1933's The Invisible Man and Rebecca of Sunnybrook Farm.
