His original intent was to help babies suffering from hydrocephalus by draining away excess fluid, but from the outset he was also interested in lumbar puncture's use as a diagnostic tool, & examined CSF for its pressure, sugar, protein, & cell count. • Widal introduced CSF cytological studies in 1901.
