Titanic sinks in the North Atlantic Ocean.

After striking an iceberg, the ship sinks 400 miles south of Newfoundland. Of the 1,514 crew members and passengers who lose their lives, many are Irish immigrants, while 651 survive. Those killed include Catherine Buckley, en route to Boston to live with her half-sister, and Harvard graduate and bibliophile Harry Elkins Widener, 27, whose mother survives and honors her son with a bequest to Harvard University in 1915.* William H. Turnquist, of 152 Spencer Street, Dorchester, was one of the few third-class passengers trapped below decks, to survive.
