E. (Ernest) Deharme

Born in 1837 and died in 1916, Ernest Deharme was a French engineer associated with the Direction des chemins de fer du Midi. He also held the railway chair at the École centrale, linking practical railway work with technical teaching.

His writing focused on locomotives and railway technology. Works attributed to him include Les Merveilles de la locomotion and La chaudière: étude de la locomotive, books that helped explain how steam engines worked at a time when rail travel was transforming everyday life.

Deharme stands out as one of those 19th-century technical authors who made complex machinery easier to understand. For listeners interested in early science writing, industry, or the romance of the railways, his work offers both expertise and period charm.
