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.
Early life
Drzewiecki was born into Polish aristocratic (
He graduated in mathematics from the École Centrale Paris and received his engineering diploma.[5] At the age of 19, he returned to Poland to take part in the January Uprising (1863-1864) against Russia. A few years later, he came back to Paris to finish his study.
Career
In 1867, Drzewiecki made his first invention, a kilometre counter for
Drzewiecki distinguished himself mainly in aviation and ship building. Beginning in 1877, during the
In 1884, he converted 2 mechanical submarines, installed on each a 1 hp engine with the new, at the time, source of energy - batteries. On tests submarine went under the water against the flow of the Neva River, Russia at a rate of 4 knots. It was the first submarine in the world with electric battery-powered propulsion.[8]
He developed the theory of gliding flight, developed a method for the manufacture of ship and plane propellers (1892), and presented a general theory for screw-propeller thrust (1920). He is known for developing several models of early submarines for the Russian Navy. In 1902, Drzewiecki designed the submarine Pocztowyj, which was powered by two combustion engines that operated both underwater and after surfacing. He also devised a torpedo-launching system for ships and submarines that bears his name, the Drzewiecki drop collar. He also made an instrument that drew the precise routes of ships onto a nautical chart.[3][9]
His work Theorie générale de l'hélice (1920), was honored by the
Remembrance
Streets named in honour of Drzewiecki are located in a number of Polish cities including Warsaw, Wrocław, Gdańsk, Poznań, Biała Podlaska, Mielec and Szczecin.[6]
In 1973, Drzewiecki and his submarine were featured on a postage stamp issued by the Polish Post in the PLN 2.70 denomination.[11]
In 1991, a monument commemorating Drzewiecki was unveiled in the Ukrainian port city of Odesa where the inventor stayed for a period of time and tested his submarine in 1878.[12][13]
In 2020, Drzewiecki was featured in a promotional publication titled Polacy światu. Znani i nieznani (Poles to the World. Known and Unknown) published by the Department of Cooperation with the Polish Diaspora and Poles Abroad of the Ministry of Foreign Affairs.[14]
