John Henry Crosby

John Henry Crosby is a translator, writer, critic, and cultural entrepreneur. 

Late in 2003, searching for a life’s work that could integrate the quest for truth, the existential need for beauty, and the service of a great good, and beginning to despair of ever finding such a mission, he called Alice von Hildebrand to propose that he spend one year translating her late husband’s Aesthetics. Would she help, he asked.

She did, and her blessing transformed his one-year plan into lifelong mission that soon attracted the collaboration of others. Thus, the life’s work he had sought found him. Established in February 2004, the Hildebrand Project’s mission to renew culture has grown to encompass publications, events, fellowships, and online resources that draw on the continuing vitality of Dietrich von Hildebrand’s thought and witness.

Under his leadership, the Hildebrand Project has become the world’s leading organization dedicated to Dietrich von Hildebrand’s legacy. The Project has been supported by many leading foundations and donors, including the Bradley Foundation, Chiaroscuro Foundation, Earhart Foundation, Fieldstead & Company, Henry Luce Foundation, Luddy Charitable Foundation, the National Endowment for the Arts, Our Sunday Visitor Institute, Papal Foundation, and the Raskob Foundation. 

He was the editor of a new edition of Dietrich von Hildebrand’s The Heart (St. Augustine’s Press, 2007). He joined John F. Crosby as co-translator of Hildebrand’s major philosophical work, The Nature of Love (St. Augustine’s Press, 2009). He edited Selected Papers in the Philosophy of Dietrich von Hildebrand (2012), the first major volume of essays on von Hildebrand in two decades. Most recently he is the primary compiler, editor, and translator of Hildebrand’s anti-Nazi papers, My Battle Against Hitler (Random House, 2014). 

His work has been featured in both popular (e.g., The Daily Beast) and scholarly publications (Logos Journal). His numerous radio appearances have taken him from PRI’s The Takeaway to the Hugh Hewitt Show. He was host of He Dared Speak the Truth, a 14-part television series on the life of Dietrich von Hildebrand, which aired on EWTN (2014).

Son of an Austrian mother and an American father, his mother tongue was German. Both his undergraduate studies in philosophy, history, and literature (2000) as well as his graduate studies in philosophy (2001) were pursued at Franciscan University of Steubenville, Ohio. 

He was for many years a violinist. As a student of Daniel Heifetz, he was formed in the great violinistic traditions of Henryk Szeryng, David Oistrakh, and Ivan Galamian. 

He serves as a trustee of The Personalist Project. 

In 2010 he married Robin-Marie Bobak. Through their marriage—and all the more with the birth of their children Magdalene (2011), Robin (2013), John Henry, Jr. (2015), and Peter—he has found (or, again, been found by) an integration of the good, true, and beautiful far greater than any he has ever known.

Christopher T. Haley

Christopher Haley is Vice President of the Hildebrand Project and Director of the Hildebrand Press. Over the past decade he has helped guide the organization’s growth from a specialist academic initiative into a vibrant cultural institution dedicated to the personalist philosophical tradition. Through publishing, communications, and program development, his work brings the thought of Dietrich von Hildebrand and kindred figures such as Karol Wojtyła, Edith Stein, and Max Scheler to new popular and scholarly audiences.

Originally drawn to philosophy by a love of beauty, Christopher studied philosophy and ancient languages at the University of Texas and later pursued graduate work at the University of Dallas, where a course on Edith Stein with philosopher Robert E. Wood introduced him to Christian personalism and helped shape the direction of his work. To this vocation he has brought both a deep grounding in the philosophical tradition and a range of professional experience—in teaching, writing, publishing, and communications—and in the Hildebrand Project these different strands of his intellectual and professional life have come together in service of a common mission.

His essays have appeared in First Things, America, and other publications. He lives in Texas with his wife and young children, and enjoys classical music, poetry, cycling, and woodworking.
