b. 1837
A French engineer and transport writer, he turned the fast-changing world of 19th-century railways and machinery into lively, readable books. His work helps modern readers see how trains, steam power, and movement itself captured the imagination of his era.

by E. (Ernest) Deharme
Born in 1837 and active into the early 20th century, Ernest Deharme was a French engineer closely tied to the railway world. Sources describe him as an engineer and study officer with the Midi Railway administration, and also as the holder of the railway chair at the École centrale.
He wrote practical and technical works on railways and locomotives, including books on railway superstructure, rolling stock, traction, and boilers. He is also known for Les Merveilles de la locomotion (1874), a popular science book that explains how people and goods move on land, water, and through the air.
Deharme seems to have stood at an interesting meeting point between industry and public education. He was not only involved in the technical side of rail transport, but also in explaining modern engineering to general readers in a clear, accessible way.
