Peter the Great
While the Poles fought the Swedes, Peter founded the city of Saint Petersburg in 1703, in Ingermanland (a province of the Swedish Empire that he had captured). It was named after his patron saint Saint Peter. He forbade the building of stone edifices outside Saint Petersburg, which he intended to become Russia's capital, so that all stonemasons could participate in the construction of the new city. Between 1713 and 1728 and in 1732–1918, Saint Petersburg was the capital of imperial Russia.
St. Petersburg paradox
The paradox takes its name from its resolution by Daniel Bernoulli, one-time resident of the eponymous Russian city, who published his arguments in the "Commentaries of the Imperial Academy of Science of Saint Petersburg" . However, the problem was invented by Daniel's cousin, Nicolas Bernoulli, who first stated it in a letter to Pierre Raymond de Montmort on September 9, 1713 .
