Davy Medal

The Davy Medal is awarded by the Royal Society of London "for an outstandingly important recent discovery in any branch of chemistry". Named after Humphry Davy, the medal is awarded with a gift of £1000. The medal was first awarded in 1877 to Robert Wilhelm Bunsen and Gustav Robert Kirchhoff "for their researches & discoveries in spectrum analysis", and has since been awarded 131 times. The medal is awarded annually, and unlike other Royal Society medals, such as the Hughes Medal, it has been awarded annually without ever missing a year.

The medal has been awarded to multiple individuals in the same year: in 1882 it was awarded to Dmitri Mendeleev and Julius Lothar Meyer "for their discovery of the periodic relations of the atomic weights"; in 1883 to Marcellin Berthelot and Julius Thomsen "for their researches in thermo-chemistry"; in 1893 to Jacobus Henricus van 't Hoff and Joseph Achille Le Bel "In recognition of their introduction of the theory of asymmetric carbon, and its use in explaining the constitution of optically active carbon compounds"; in 1903 to Pierre Curie and Marie Curie "for their researches on radium" and in 1968 to John Cornforth and George Joseph Popjak "in recognition of their distinguished joint work on the elucidation of the biosynthetic pathway to polyisoprenoids and steroids".
