I found this (relatively) recently published article reviewing Bleuler's Dementia Praecox or the Group of Schizophrenias which is the book where he first publishes the terms "Schizophrenia" and "Autism." Though Bleuler was using the words with his colleagues starting a few years earlier. (Cf. Freud-Jung Correspondences, May 1907[0], you can ctrl-f "autism,""schizophrenia," etc.)
