means A unit of electric charge (and the name forever attached to Michael Faraday, the self-taught scientist whose experiments with electricity and magnetism laid the groundwork for generators, motors, and modern electromagnetism), used especially in chemistry to measure the charge carried by one mole of electrons.

from Named after Michael Faraday (1791–1867), a bookbinder's apprentice who read his way into science and became one of the great experimentalists of his age, discovering electromagnetic induction and the laws of electrolysis. The 'faraday' as a unit of charge was coined by later scientists in his honor, distinct from the 'farad' (the unit of capacitance), which was also named after him — a small but genuine source of confusion ever since, since both words spring from the same man but measure different things.
