Hygrometer
notes: label: Description
content: In 1783, Horace Benedict de Saussure, a Swiss physicist and geologist, used the expansion and contraction of human hair to measure humidity. This wooden and obviously home-made hair example of Saussure’s hygrometer probably belonged to, and was probably made by, Henry Fitz (1808-1863), America’s first successful commercial telescope maker.
