Alphonse Eléonor Sagebien (1807-1892) was a French
hydrological engineer born in
Amiens and the inventor of the
Sagebien wheel
The Sagebien wheel is a type of water wheel invented by Alphonse Sagebien of France, a hydrological engineer and a graduate of the École Centrale des Arts et Manufactures. It was one of the most efficient breastshot water wheel designs of its era; ...
- a device that made hydraulically powered systems much more efficient in extracting energy from moving water.
Sagebien graduated in 1833 with a degree in engineering from the prestigious
École Centrale des Arts et Manufactures and worked primarily in
metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys.
Metallurgy encompasses both the sc ...

Pas-de-Calais (, " strait of Calais"; pcd, Pas-Calés; also nl, Nauw van Kales) is a department in northern France named after the French designation of the Strait of Dover, which it borders. It has the most communes of all the departments ...
. After 1848, he shifted to hydrological engineering, designing and patenting the wheel that bears his name. This invention was able to extract 50% more energy from flowing water than previous paddle-based systems and is still used today.
Sagebien was also a municipal counsellor for Amiens from 1878 to 1888.
