L'Arche is an international federation of non-profit organisations working to create networks of community where people with and without intellectual disabilities live and work together. Founded in 1964 by Jean Vanier, Raphaël Simi, and Philip Seux, L'Arche emerged as a reaction and community-based alternative to the ill-treatment and dismal living conditions in the psychiatric institutions of the 1960s.

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.
