The design and production of the Felix Klein and Hans Freudenthal medals was done at Ã‰cole Boulle in Paris, a renowned French school of art and design. Founded in 1886, Ã‰cole Boulle is named after a famous cabinet-maker of King Louis the 14th, AndrÃ©-Charles Boulle, after whom is also named a well-known curved chest of drawers. The ICMI medals, produced as a project in a course for students completing their degree at Ã‰cole Boulle, were conceived and made by Thomas Soufflard. The technique used by the student is that of modelled engraving, where a hollowed or relief motif is obtained by cast, strike, or ornamentation. The engraving was made by hand and the first medals were stroke-pressed a few weeks before ICME-10 at the Monnaie de Paris, using a special 600-ton press. The 2005 and 2007 medals have been pressed at the Ã‰cole Boulle.
