1967: Grigori Rasputin was murdered in Petrograd on the night of 29 December 1916. Prince Felix Yusupov and his fellow conspirators poisoned Rasputin with cyanide, shot him four times, clubbed him, kicked him, tied him up and finally pushed him through a hole in the ice on the River Neva.
After the Russian Revolution, Yusupov fled abroad and lived most of the rest of his life in Paris. He died on 27 September 1967 at the age of 80 – unlike Rasputin, from natural causes.
