Life

Drzewiecki was born into Polish aristocratic ( szlachta) family of national patriots. His grandfather Józef Drzewiecki served under generals Kościuszko and Dąbrowski. His father Karol Drzewiecki took part in the November Uprising against Russia. Young Stefan was sent by him away from partitioned Poland to complete his education in France. At the beginning of 1860. Drzewiecki was admitted to L'Ecole Centrale des Arts et Manufactures, however he postponed finishing his engineering studies to take part in January Uprising (1863-1864) against Russia. A few years later, he came back to Paris to finish his study. With a knack for creativity and invention, Stefan Drzewiecki invented such useful tools as the kilometric counter for

, he developed several models of propeller-driven submarines that evolved from single-person vessels to a four-man model. 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. 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 also developed several models of early submarines for the Russian Navy, and 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
