The clinical psychology of Lightner Witmer: a case study of institutional innovation and intellectual change

The name Lightner Witmer is rarely invoked in the historian's litany of psychological saints. Neither a grand systematizer nor an ardent experimentalist, the "world's first clinical psychologist" is even dismissed by contemporary clinicians because of his purported failure to achieve for psychologists professional hegemony over the "problem child." Yet disciplinary ventures which in Joseph Ben-David's phrase fail to "take off" represent extremely illuminating indicators of a discipline's shifting ideas, roles, and aspirations. Explicitly urging that historians pay more attention to subgroups of larger disciplines, this paper constitutes an attempt to assess the impact of changing social roles upon psychologists' intellectual stances through an examination of Witmer's novel activities at the University of Pennsylvania.
