Dietrich von Hildebrand (1889–1977) was born in Florence. He converted to Catholicism in 1914. He taught philosophy at the University of Munich. Soon after the end of World War I, Dietrich denounced Nazism in articles and speeches throughout Germany and the rest of Europe. He left Germany for Austria and then fled Austria, just as it fell to the Nazis, when Hitler gave orders for his assassination. During this time he wrote Transformation in Christ. At last Dietrich arrived safe but penniless in New York, where he was hired as professor of philosophy at Fordham University. He died in 1977 in New Rochelle, New York.
Alice von Hildebrand was born in 1923 in Belgium and came to America in 1940. In 1949 she earned her Ph.D. in philosophy from Fordham University. There she met and studied under philosopher and anti-Nazi exile Dr. Dietrich von Hildebrand, whom she married. In 1947, Alice was hired as the first woman to teach philosophy at Hunter College (CUNY) in New York City. She has given hundreds of lectures throughout the United States, South America, and Europe. With Dietrich von Hildebrand, she collaborated on a number of major works, including The Art of Living. Alice von Hildebrand currently has in preparation numerous other works, including books on wisdom, widowhood, feminism, C.S. Lewis, Kierkegaard, and Plato. (Sophia Institute Press Bios)
