The concepts and techniques involved in the origins of psychosurgery during the
late nineteenth century are analysed, particularly in the work of Claye Shaw
and Gottlieb Burckhardt. It is shown that their views and therapeutic behaviour
were guided by scientific, ethical and social warrants not dissimilar from those of
today. The debate that followed their work can thus be considered as a trial run
to that elicited by the work of Moniz. This paper focuses on the work of Shaw,
Cripps, Tuke and Duncan for, until now, it has not featured in any history of
psychosurgery. From the point of view of the history of science, their work is
important, for it relates to the debate on brain localization, neuronal circuits
and the neurobiological representation of mental illness that took place at the
dawn of the twentieth century. Nothing is said on the history of psychosurgery
subsequent to the work of Moniz.
