Eduard Hedvicek (; 17 March 1878 in KojetÃÂn â 12 September 1949 in Vienna) was the secretary of Engelbert DollfuÃÂ, the Austrian Chancellor before the Anschluss. On 25 July 1934 he unsuccessfully tried to prevent DollfuÃÂ's assassination by Otto Planetta. He testified at the trial of the murderers as a "Crown" (prosecution) witness and was awarded the Gold Medal of Merit Signum Laudis by the Austrian government for his heroic efforts. He was imprisoned by the Nazis after Germany annexed Austria. His imprisonment was a matter of personal revenge for Ernst Kaltenbrunner, the SS-Obergruppenführer and Chef der Reichssicherheitshauptamtes of the Nazi government and a famous Austrian Nazi, who himself was involved in DollfuÃÂ's assassination and was for this and other crimes hanged after the war.
