Because of his outstanding services, Hedin was raised to the untitled nobility by King Oskar II in 1902, the last time any Swede was to receive a charter of nobility. Oskar II suggested that he prefix the name Hedin with one of the two common predicates of nobility in Sweden, "af" or "von", but Hedin abstained from doing so in his written response to the king. In many noble families in Sweden, it was customary to do without the title of nobility. The coat of arms of Hedin, together with those of some two thousand noble families, is to be found on a wall of the Great Hall in Riddarhuset, the assembly house of Swedish nobility in Stockholm's inner city, Gamla Stan.
