Short biography of Ulysse Valentin

Ulysse Valentin (active from the early 20th century) was a professor of automotive engineering in Hoei and Marchin (Liège province, Belgium). He trained young technicians and driver-mechanics during a time when the automobile was still in full development. Valentin was known for his didactic approach, producing large and precise diagrams that helped students understand the workings of engines and vehicles.

His education reflects the transition from horse-drawn carriages to cars. The signatures and stamps on his students' drawings and diplomas make these documents valuable testimonies of the early history of motorsport in Wallonia.
