Gloria Stuart, best known for dropping that large necklace into the water in Titanic, passed away on Monday. She was 100 years old.

Although she had been appearing in movies since the 1930s, Stuart finally made film history in 1997. That was when the then 87-year-old actress became the oldest Oscar nominee ever. (She received a Best Supporting Actress nod for playing the 101-year-old version of Rose in the hit James Cameron film.)

Gloria, who had been diagnosed with lung cancer a few years back, died in her Los Angeles home. She leaves behind a daughter, four grandchildren and 12 great-grandchildren.
