[Jelgersma and his clinic].

Gerbrandus Jelgersma (1859-1942) became in 1899 the first professor of psychiatry at Leiden University. Until then he had been employed in psychiatric asylums, first as pathologist and later as managing director. His scientific work was at first exclusively devoted to the microscopic structure of the brain, by which he attempted to find correlations between structure and function. In addition he had a wide knowledge of psychopathology. Gradually he incorporated Freud's psychoanalytical doctrine in his teaching and in his therapeutic methods, but as a scientist he remained faithful to the morphological approach. At the age of 72 he published a monumental atlas of the brain. In 1950 the municipal hospital in Leiden for short-term psychiatric treatment was named after him.
