Jean-Ovide Decroly (1871-1932): neurologist and pedagogue

The present article aims to understand Ovide Decroly1s intervention in the pedagogical field considering his medical-neurological training. Thus, it shows that, in 1901, Decroly founded an institute of special education and, 6 years later, created the Hermitage School, for disabled and so-called normal children respectively. In these educational endeavors, Decroly used the mental tests of the Binet-Simon scale, but indicating their limits; and in the light of the experience of American psychology, in the 1920s, he developed, with Raymond Buyse, the Decroly-Buyse tests.
