Conte Giuseppe Angelo Saluzzo di Monesiglio to Benjamin Franklin, July 1, 1784
Conte Giuseppe Angelo Saluzzo di Monesiglio informs Benjamin Franklin about a new musical keyboard invention by Abbé Perno Piémontois that allows playing airs like a harpsichord and inquires if similar devices exist in Paris, London, or elsewhere. He offers to send a description and design of the mechanism and invites Franklin to contribute to the upcoming first volume of the Academy's new memoirs.
