Franz M. (Franz Maria) Feldhaus

Born in 1874 and active in Germany, Franz Maria Feldhaus became known as a historian of technology and engineering. Reliable biographical sources identify him as an important early scholar in the field, and his name is closely associated with documenting the development of inventions, crafts, and industrial techniques.

Feldhaus is especially remembered for building and using a large private collection devoted to the history of technology. That hands-on interest gave his writing a practical flavor: instead of treating technical history as abstract theory, he focused on real devices, makers, and processes.

He died in 1957, leaving behind work that helped shape the study of the history of technology in the German-speaking world. For listeners interested in older scientific and technical culture, he stands out as a guide to how inventions emerge from everyday work, experimentation, and skilled craft.
