Atwood Machine

Description:

George Atwood, a mathematics tutor at Trinity College, Cambridge, described this type of instrument in 1784, explaining its use for verifying the laws of motion with constant acceleration. The Atwood machine soon became a common piece of classroom apparatus, suitable for teaching classical mechanics.

This example was used at the U.S. Military Academy. The “Fortin et Herrmann Genre à Paris” inscription refers to Adolphe and Émile Fortin-Herrmann, brothers who, in 1831, took over the shop of their grandfather, Nicholas Fortin, a leading scientific instrument maker in Paris.
