Benjamin Franklin (1706-1790), statesman, scientist, and inventor, was born in Boston, Mass. He established himself in the printing business in Philadelphia, Pa, which is where he became involved in politics and science. While serving as the US ambassador to France, he invented bifocal spectacles in 1784.
The firm Bausch and Lomb, commemorating the 150th anniversary of this invention in 1934, issued a medal of Franklin holding a pair of his bifocal spectacles. It was engraved by Felix Weil and created by the firm Medallic Art Co (Figure 1 andFigure 2).
