Conrad's main work: ''Die beginnende Schizophrenie. Versuch einer Gestaltanalyse des Wahns (1958)'', describes the early state of schizophrenia and the typical schizophrenic aspects. From this monograph, terms as "Trema", "Apophänie" (apophany), and "Überstieg" were coined. Frank Fish, who had reviewed Conrad's book in 1960, used Conrad's approach in a neuropsychiatric case report the same year. An English language summary of Conrad's work and its influence was published in 2010 by Mishara. Provided by Wikipedia
