I want to thank Dr. Franz GrafMeran for permitting me to use Archduke Johann's diaries and letters in the Steiermarkisches Landesarchiv, Graz, as well as Dr. Walter Puschnigg and the other gentlemen of that archive for their kind assistance. I am also extremely grateful for the patient, friendly and unsparing helpfulness and advice from the ladies and gentlemen of the Haus-, Hof-und Staatsarchiv in Vienna. In particular I would like to thank w.Amtsrat Anton Nemeth for his aid in deciphering and transcribing numerous documents.
