I recently bought a used paperback copy of The Fifty-Minute Hour, Robert Lindner's bestselling 1954 study of some of his most interesting psychoanalytic cases. The book caught my eye because my father, who died almost eight years ago, would talk about this book when I was a child. Seeing the title brought a vivid rush of memories.
I did find Internet discussions of the identity of the planet hopping man. One popular idea is that he is Cordwainer Smith (see http://www.ulmus.net/ace/csmith/behindjetcouch.html) , who published the sci-fi work Norstrilla.
So, to finish, every once in awhile we discover books that put us in touch with the past in more ways than one. Has this happened to you?
