john mark freeman -lrb- january 11 , 1933 -- january 3 , 2014 -rrb- was an american pediatric neurologist specializing in epilepsy .

one , the ketogenic diet , is a carefully managed , high-fat diet plan that reduces the incidence of seizures in children during and after its use , and the other , the hemispherectomy , is a drastic surgical procedure in which part or all of one highly seizure-prone hemisphere of the brain is removed to alleviate severe epilepsy .
