Josef Ressel

Josef Ressel was a Czech-German inventor and forestry officer who lived from 1793 to 1857. He was born in Chrudim, Bohemia, and died in Ljubljana. Ressel is best known for inventing the naval propeller, for which he was granted a patent in 1827[3]. He also contributed significantly to the development of steam-powered ships.

Ressel graduated from a grammar school and an artillery academy. He worked as a forestry officer for many years, during which time he developed his interest in ship propulsion. In addition to his work on the naval propeller, Ressel designed a steam-powered ship tested on the Danube River in 1829.

Today, Ressel is remembered as a pioneering inventor who helped revolutionise ship propulsion. His contributions to the development of steam-powered ships and the naval propeller have impacted the maritime industry.
