Michael Faraday(1791-1867)

The laws of electrolysis were discovered by Michael Faraday, perhaps the most talented experimental scientist in the nineteenth century.
Faraday developed the laws of electrolysis between 1831 and 1834. In mid-December of 1833, he began a quantitative study of the electrolysis of several metal cations, including tin(II), lead(II) and zinc(II) ions. Despite taking a whole day off for Christmas, he managed to complete these experiments, write up the results of three years work, and get his paper published in the Philosophic Transactions of the Royal Society on January 9, 1834. In this paper, Faraday introduced the basic vocabulary of electrochemistry, using for the first time the terms "anode", "cathode", "ion", "electrolyte", and " electrolysis".

To Michael Faraday, science was an obsession; one of his biographers described him as a "work maniac". An observer said of him,
...if he had to cross the laboratory for anything, he did not walk, he ran; the quickness of his perception was equalled by the calm rapidity of his movements.
