100 years ago today, the RMS Titanic sank. Five years later, one of the ship's best historians was born in Baltimore... Walter Lord (1917-2002), whose grandfather was head of one of the city's Old Bay steamship line, had a lifelong interest in the sea, concentrated into a vast knowledge of the Titantic disaster. While at Gilman School, he delivered his senior speech on the subject, and he went on to write the book A Night to Remember, an honored non-fiction account of the event, which became a 1958 British movie. Then, in 1997, he was a consultant to James Cameron's blockbuster Titantic film.
