AB  - In honor of Isaac Ray's 200th birthday, the author examines his early career for an example of critical thinking about expert testimony. Ray, a scientist from the outset, expressed interest in phrenology, a contemporary science of the mind. This paper explores a criminal case from Maine in which phrenological testimony was proffered and which Ray critiqued. The author then examines Ray's standards of practice in relation to present concepts of admissibility of expert testimony. He concludes that Ray's quality standards remain evident in contemporary efforts to apply evidence-based science to legal matters.
