Born in Germany this unusual scientist, established in neuroanatomy as well as in neuropathology, contributed considerably to both areas. Early on he concentrated on myelogenesis of the spinal cord earning as a result the dorsal spinocerebellar tract to be called "Flechsig’s tract." His work also extended to other primary systematic diseases of the spinal cord to the anatomy of many structures in the brain to include the myelogenesis of the internal capsule that he subdivided into its present nomenclature as anterior/posterior limb and knee. Numerous students flocked to him from everywhere and he soon embarked on the pathology of tabes dorsalis, the treatment of general paresis and even the convulsive state. He next turned to the study of myelogenesis of the brain hemisphere but many of his theories were disputed.
