Ludwig Binswanger
Being-in-the-World:
Selected Papers of Ludwig Binswanger
Introduced by Jacob Needleman
(New York: Harper & Row, 1967)
Binswanger was a psychotherapist with existential leanings.
Two of his cases are quoted at length in the chapter on anxiety
in Our Existential Predicament.
But much more will be found in this comprehensive volume.
Another Binswanger case of angst quoted in the anxiety chapter
is drawn from Existence: A New Dimension in Psychiatry and Psychology
edited by Rollo May et al. (New York: Basic Books, 1958)

James Leonard Park, existential philosopher.
