Stefan Drzewiecki (Polish: [ˈstɛfan d͡ʐɛˈvjɛt͡skʲi]; Russian: Джеве́цкий Степа́н Ка́рлович (Казими́рович); 26 July 1844, Kunka, Podolia, Russian Empire (today Ukraine) – 23 April 1938, Paris) was a Polish scientist, journalist, engineer, constructor and inventor, known for designing and constructing the world's first electric-powered submarine. He worked mainly in France and the Russian Empire.[1][2][3]
He built the first submarine in the world with electric battery-powered propulsion in 1884. He also independently developed the blade element theory (BET), a mathematical process used to determine the behavior of propellers.
