Shortly after ending his recital with a bow, he collapsed and was pronounced dead at the scene.

Lafayette reportedly proclaimed that he would not live much longer after Beauty's death. Four days later, he was performing at the Empire Palace Theatre in Edinburgh, Scotland, when a fire broke out and engulfed the stage within minutes. The audience, thinking that this was all part of the illusion, did not evacuate until the theatre manager signaled for the orchestra to play God Save the King.

Before 1916, American scholars and scientific community doubted that sharks would fatally wound a living person in the temperate waters of the northeastern United States without provocation. The attack led to a wave of panic that led to shark hunts aimed at eradicating the population of "man-eating" sharks, and entered into American popular culture, serving as an inspiration of the novel Jaws and its film adaptation.Grigori Rasputin 30 December [O.S.17 December] 1916The 47-year-old Russian mystic died of three gunshot wounds, one of which was a close-range shot to his forehead.

He was then shot once in the chest and believed to be dead but, after a while, he leapt up and attacked Yusupov, who freed himself and fled. Rasputin followed and made it into the courtyard before being shot again, and collapsing into a snowbank. The conspirators then wrapped his body and dropped it into the Malaya Nevka River.Gustav KobbéThe 61-year-old author and music critic was sailing in Great South Bay, New York, when he noticed a low-flying seaplane heading toward him.
