Michael Faraday
1791 – 1867
Electromagnetic induction and the groundwork for the field concept.
Born poor and largely self-educated, Faraday became the greatest experimentalist of the 19th century. His discovery of electromagnetic induction in 1831 is the principle behind every transformer, generator, and motor.
He declined a knighthood and the presidency of the Royal Society, preferring the bench. The unit of capacitance honors him; the transformer tools here run on his induction.
