Yes, Millvina Dean is the last remaining survivor. Read the interview - she's quite an interesting woman, and, at 97, obviously still has all her faculties.
That reminds me that I read a book awhile ago, probably prompted by someone here or this thread, called Titanic Survivor: The Memoirs of a Stewardess, the story of Violet Jessop. She survived the Brittanic, too! It was a very interesting read, if anyone is intrigued. Her life was just fascinating, really, and her first-hand accounts of these two tragedies (as well as life on several other ships) is compelling.
That was me that recommended the book. And, not only the Titanic and Britannic, she also survived the Olympic!
I can quite imagine that, as they felt and heard the torpedo hit, she must have put down her teacup and sighed melodramatically, "Oh boy, here we go
again."
