One of my favorite 19th century electrical scientists is Edward Weston, and one of my favorite devices for teaching the topics of electromagnetic forces and torques is the D'Arsonval galvanometer.1 The junction of these two topics is Weston's improved meter movement that has been used in analog meters for the past 125 years.

There are several public figures named Edward Weston. Most of us will immediately think of the photographer Edward Weston (1886–1958), who is known for his photographs of the Yosemite. There is also a famous 19th-century long-distance pedestrian with the same name.
