Scholars debate whether Nini met Benjamin Franklin personally or based the nine versions of his portrait on drawings by artist Thomas Walpole (British, 1755-1840). In this particular cast, Nini presents Franklin with a fur hat, which may be an allusion to French philosopher Jean-Jacques Rousseau, suggesting a comparison between the inventor and the philosopher and their roles in revolutionary politics on both sides of the Atlantic. Nini copied Franklin's fur hat from a portrait of Rousseau by Allan Ramsay (Scottish, 1713-1784). The small crest below Franklin's left shoulder shows a bolt of lightning striking an iron bar held by a hand, a reference to Franklin's discovery of the lightning rod and electricity.
