Dietrich Richard Alfred von Hildebrand (12 October 1889 – 26 January 1977) was a German Roman Catholic philosopher and religious writer. Hildebrand was called "the twentieth-century Doctor of the Church" by Pope Pius XII. He was a leading philosopher in the realist phenomenological and personalist movements, producing works in every major field of philosophy, including ethics, metaphysics, epistemology, philosophical anthropology, social philosophy, and aesthetics. Pope John Paul II greatly admired the philosophical work of Hildebrand, remarking once to his widow, Alice von Hildebrand, "Your husband is one of the great ethicists of the twentieth century." Benedict XVI also has a particular admiration and regard for Hildebrand, who knew Ratzinger as a young priest in Munich: "When the intellectual history of the Catholic Church in the twentieth century is written, the name of Dietrich von Hildebrand will be most prominent among the figures of our time." Hildebrand is known for his consistent, public opposition to Nazism before and during World War II.

He received his early education from private tutors. Although raised in a home without religion, Hildebrand developed a deep sense for beauty, value, and the sacred from an early age. Sent to Munich at the age of fifteen for his Abitur, Hildebrand enrolled at the University of Munich two years later, where he joined a circle of students who first followed the philosopher Theodor Lipps but soon were swayed by the teachings of Edmund Husserl. Through this circle he came to know Max Scheler, through whose influence (and through his depiction of St. Francis of Assisi) Hildebrand converted to Catholicism in 1914. In 1909 he attended the University of Göttingen, where he completed his doctorate in philosophy under Husserl and Adolf Reinach, whom he later credited with helping to shape his own philosophical views. In 1912, he married Margarete Denck, and with her had one child, Franz. In 1914, he and his wife were received into the Catholic Church. Upon the outbreak of the First World War Hildebrand was drafted into service as a physician's assistant in Munich, serving as a kind of surgical nurse. Hildebrand published his first book, The Nature of Moral Action (Die Idee der Sittlichen Handlung), in 1916, and two
