I would like to express my gratitude to the Graduate Center of the City University of New York for having received a summer grant for research in Austria. I want to thank Dr. Franz Graf Meran 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. Finally, I am most grateful for the counsel, help and encouragement by Prof. Andrew Whiteside of Queens College and City University of New York, and for the many valuable suggestions made by Profs. Robert A. Kann of Rutgers University, Paula S. Fichtner and Bela K. Kiraly, both of Brooklyn College.
