On this day (May 7) in 1915, a German torpedo sank the British passenger liner R.M.S. Lusitania off the southern coast of Ireland, killing about 1,195 passengers and crew (published accounts differ on the exact number). Among the victims were two well-known editors of the day, Elbert Hubbard, editor of The Philistine, and Herbert S. Stone, editor of The House Beautiful. Coincidentally, Hubbard seems to have been fascinated by the sinking of another British liner, the Titanic, three years earlier, and wrote a number of pieces, like this one, about it.
An article of mine about famous people who missed the Lusitania is currently on the Smithsonian magazine website.
