Hughes Medal

The Hughes Medal is awarded by the Royal Society of London "in recognition of an original discovery in the physical sciences, particularly electricity and magnetism or their applications". Named after David E. Hughes, the medal is awarded with a gift of £1000. The medal was first awarded in 1902 to J. J. Thomson (pictured) "for his numerous contributions to electric science, especially in reference to the phenomena of electric discharge in gases", and has since been awarded over one hundred times. Unlike other Royal Society medals, the Hughes Medal has never been awarded to the same individual more than once. The medal has on occasion been awarded to multiple people at a time; in 1938 it was won by John Cockcroft and Ernest Walton, in 1981 byPeter Higgs and Tom Kibble, in 1982 by Drummond Matthews and Frederick Vine and in 1988 by Archibald Howie and M.J. Whelan.

SAI KZ IV

The SAI KZ IV was a light twin-engined aircraft first built in Denmark in 1944 for use as an air ambulance. A single machine was built during the war, and was used by Folke Bernadotte while negotiating for the release of Danish prisoners in German concentration camps. It is now held by the Danmarks Flymuseum and has been restored to its original wartime configuration and markings. A second aircraft was built and flown in 1949, remaining actively operational until the mid 1960s.
