Dr. Lidz's paper is the introduction to a special section on Adolf Meyer in this issue of the American Journal of Psychiatry. Lidz believes that Meyer was one of the two great psychiatrists who changed the face of contemporary psychiatry, and that psychoanalysis itself found fertile ground in this country because it had been prepared by the genetic approach of Meyer. Lidz points out that at the 1909 Clark University series, Meyer was almost alone in maintaining the psychogenicity of schizophrenia. This is an excellent introduction to a reacquaintance with Meyer's thought.
