Henri Jozef Machiel Nouwen (1932 – 1996) was a Dutch Catholic priest, professor, writer and theologian. His interests were rooted primarily in psychology, pastoral ministry, spirituality, social justice and community. Over the course of his life, Nouwen was heavily influenced by the work of Anton Boisen, Thomas Merton, Rembrandt, Vincent van Gogh and Jean Vanier.

After nearly two decades of teaching at academic institutions including the University of Notre Dame, Yale Divinity School and Harvard Divinity School, Nouwen went on to work with mentally and physically handicapped people at the L'Arche Daybreak community in Richmond Hill, Ontario.
