Féru des Sciences, Science museum in Jarville-la-Malgrange, France.

Féru des Sciences is a science museum in Jarville-la-Malgrange, near Nancy, devoted to iron and its derivatives from the Middle Ages to the 20th century. A scale model in a glass case shows an ironworks: open sheds with dark pitched roofs, a tan building with eight arched windows, and behind it pipes, a chimney and a framework tower.

The museum opened as the Musée de l'Histoire du Fer, with collections assembled from the 1950s by Édouard Salin, Bertrand Gille, Albert France-Lanord and Georges Henri Rivière. In 1965 its inventory listed about 500 objects; by November 2019 it held 13,243 recorded units. It is now the Féru des Sciences, run by the Grand Nancy Métropole.

The museum's collections were assembled by specialists including Édouard Salin, founder of the Centre de Recherche de l'Histoire de la Sidérurgie, Bertrand Gille and Albert France-Lanord, with Georges Henri Rivière advising on the museography. The metal archaeology laboratory produced facsimiles and models for the displays. A deposit from the Musée lorrain brings some 84 archaeology and ethnography objects linked to iron trades, presented from the Diderot and d'Alembert encyclopedias.

The museum is in the Parc de Montaigu in Laneuveville-devant-Nancy, next to the Château de Montaigu, a short distance from Nancy. The collections are displayed indoors, and the scale models and graphic works are best examined at a leisurely pace. The park setting allows visitors to combine the museum with a walk through the grounds.

A special area called Espace à Bidouilles invites visitors to conduct their own experiments and explore physics and chemistry concepts related to iron. This hands-on approach makes scientific ideas understandable through direct experience.
