In honor of Jurgen Ruesch: Remembering his work in psychiatry.

While some of Ruesch's ideas about the nature and origins of communication has been discounted, many of his preoccupations are now part of the mainstream, and it is to here that we should look for evidence of his legacy. In fact, he has been the author of rich and fruitful ideas, which are essential to clinical understanding of mental diseases and their treatments. It is not surprising, therefore, that Ruesch's burning interest in the clinical assessment of normal and pathological communicative behavior finds a significant echo in today's proliferation of books, papers, and conferences on communication. For all that, we should honor him.
