(July 26, 1844 in Kunka
, Russian Empire
) – April 23, 1938 in Paris
) was a Polish
scientist, journalist, engineer, constructor and inventor, working in Russia
Drzewiecki left Poland early in life to complete his education in France. With a knack for creativity and invention, he invented such useful tools as the kilometric counter for cabs. At the specific request of Grand Duke Konstantin
, Drzewiecki moved to St. Petersburg in 1873. While in Russia, he constructed an instrument that drew the precise routes of ships onto a map.
Drzewiecki distinguished himself mainly in aviation and ship building. Beginning in 1877, during the Russo-Turkish War
, he developed several models of propeller-driven submarines that evolved from single-person vessels to a four-man model. 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.
His work "Theorie generale de l'helice
" (1920), was honored by the French Academy of Science
as a fundamental work in the development of modern propellers.
