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 taxicabs.
In 1873 at the age of 29. he moved to Saint Petersburg. In Russia Drzewiecki had a fruitful career as a mechanical engineer. 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).
His work Theorie générale de l'hélice (1920), was honored by the French Academy of Science as fundamental in the development of modern propellers.
