Edwin Herbert Hall (November 7, 1855 – November 20, 1938) was an American physicist, who discovered the electric field Hall effect. Hall conducted thermoelectric research and also wrote numerous physics textbooks and laboratory manuals.
Edwin Hall’s discovery that Tuesday in late October of 1879, which came to be called the Hall effect, may be one of the most underappreciated achievements in the history of Hopkins. Over the past 140 years, the Hall effect has become an indispensable tool for measuring the strength of electromagnetic fields.
Edwin Hall’s experiment, performed almost exactly one hundred years ago, had an elegant simplicity to it. A current from a carbon-zinc battery was passed through a strip of gold foil (2 cm. × 9 cm.) fixed firmly on a glass plate by means of brass clamps.

On 28 October 1879, the 23-year-old Hall made a discovery that still reverberates today (and which would eventually lead to Nobel Prizes for four other people). Working in a physics lab at the newly created Johns Hopkins University, Hall saw a needle in a galvanometer gauge shift, indicating an electric potential that had no obvious cause.
