Description
Photographic barographs came into use in the middle years of the nineteenth century. This example is allegedly a replica of one made by Jean Adrien Deleuil, a scientific instrument maker in Paris. L. C. Eichner, the craftsman who made it for the Museum, wrote: “I have aimed at making and instrument such as might be made in a university laboratory shop; designed by the professor and made by him and his mechanic. In other words: with a somewhat ‘home-made’ look.”
