Last known Titanic survivor dies

LONDON, England (CNN) - Millvina Dean, believed to be that last survivor of the Titanic, has died at 97, a friend confirmed Sunday.

Dean was just an infant when the RMS Titanic - publicized as "practically unsinkable" as the largest passenger steamship at the time - struck an iceberg on the night of April 14, 1912 during its maiden voyage. The ship sank less than three hours later, killing more than 1,500 people.

Brian Ticehurst, a friend of Dean, said she died at 8 a.m. (3 a.m. ET) Sunday.
