[Electroplating the Platinum Metals 銀メッキ、金メッキ] text
French inventor, Henri-Catherine, Count of Ruolz, Montchal, music composer and chemist, was born in Paris in 1809 and died in Neuilly-sur-Seine in 1887. He worked extensively on silverplating techniques taking out a number of patents including one for a nickel-based white metal alloy.

By experimenting the effects of the electric current on solutions of salts of gold or silver, the brother ELKINGTON in England and the Count Henri de RUOLZ-MONTCHAL in France recognized that by substituting for the middle-of-the-road or acid solutions of golden salts and some salts of silver of the dissolutions of these same salts in the presence of an excess of cyanide of potassium or potassium ferrocyanide, it was possible to obtain a deposit member of gold or silver on the electrode connected with the negative pole of the source of current.
