Elizabeth Gladys Dean of Southampton, England, known as Millvina, who was 2 months old at the time the Titanic sank, is now the only remaining survivor, according to the Titanic Historical Society. The last American survivor, Lillian Gertrud Asplund, died in Massachusetts last year at the age of 99.

Ms. Dainton, born in Bournemouth, in southern England, in 1911, was too young to remember the night when the huge liner hit an iceberg and sank in the Atlantic on April 14 and 15, 1912, killing 1,500 people, including her father, Edwy Arthur West.
