Josef Seifert received his doctorate in philosophy from the University of Salzburg in 1969 and, under Professor Robert Spaemann, his habilitation from the University of Munich (Privatdozent) in 1975. He studied chiefly under Balduin Schwarz, the most distinguished German former student of Dietrich von Hildebrand, at the University of Salzburg, and under Gabriel Marcel in Paris. Already as a child (from age 3 on) he knew Hildebrand personally, because Seifert’s mother had been a student of Hildebrand in Munich and both of his parents were Hildebrand’s friends. He is the author of many books, and Europe’s leading student and teacher of Hildebrand’s philosophy.
Mark K. Spencer is Associate Professor of Philosophy at the University of St. Thomas and Fellow for the Hildebrand Project. He earned his Ph.D. from the University at Buffalo, and his M.A. and B.A. from Franciscan University of Steubenville, where he first encountered the work of Dietrich von Hildebrand. In his research, he focuses on topics like the human person, beauty, and God's relations to us. In over thirty articles, he has brought together many approaches to these topics, including Thomism, Scotism, phenomenology, personalism, and Greek patristics. He lives in St. Paul, Minnesota with his wife, Susanna, and their four children.
