ジャック・ネッケル
His portrait of Benjamin Franklin (circa 1785), more than any other, has fixed the image of Franklin for posterity since it is reproduced on the U.S. hundred dollar bill. His portrait of the financier Jacques Necker hung at Voltaire's Coppet Castle. Several reduced versions were made, one of which is at the Louvre. Many of his portraits received a wider circulation as engravings.
