Diagnostic des maladies de la moëlle, published in 1899, detailed the Grasset law, a clinical observation regarding hemiparesis. Joseph Grasset identified this phenomenon where a patient unable to raise both legs simultaneously while supine retains the individual capacity to lift either leg separately. This contribution represents a portion of his extensive academic output within French neurology.
Academic and Clinical Career
Born in 1849 in Montpellier, France, Grasset remained anchored to his home city throughout his professional life. After earning his medical degree from the Faculty of Medicine of Montpellier in 1873, he joined the institution as a faculty member. He secured a professorship of therapy in 1881, transitioned to the chair of clinical medicine in 1886, and eventually assumed the chair of general pathology in 1909. His career encompassed the breadth of internal medicine, though he focused primarily on the neurological system.

Beyond traditional neurology, Grasset explored psychiatry and the boundaries of occult phenomena. He authored Demi-fous et Demi-responsables in 1907 to examine questions of partial responsibility. His investigations into the paranormal, represented by titles such as 1904's Le spiritisme devant la science and 1907's L’occultisme hier et aujourd'hui, reflected a psychological methodology. In his 1910 English translation, The Marvels Beyond Science, he argued that mediumship resulted from unconscious suggestion or intentional deception.
Legacy and Distinctions
Throughout his tenure, Grasset produced numerous specialized texts, including The Diagnosis of Diseases of the Cord, released in 1901. In recognition of his service to the French medical community, he was named an Officer of the Legion of Honour. Grasset died in 1918 at the age of 69 and was interred at the cemetery Saint-Lazare in Montpellier.
