The John Price Wetherill Medal was an award of the Franklin Institute. It was established with a bequest given by the family of John Price Wetherill (1844–1906) on April 3, 1917. On June 10, 1925, the Board of Managers voted to create a silver medal, to be awarded for "discovery or invention in the physical sciences" or "new and important combinations of principles or methods already known". The legend on the first medal read: "for discovery, invention, or development in the physical sciences". The John Price Wetherill Medal was last awarded in 1997. As of 1998 all of the endowed medals previously awarded by the Franklin Institute were reorganized as the Benjamin Franklin Medals.
