HELLP syndrome was identified as a distinct clinical entity (as opposed to severe pre-eclampsia) by Dr. Louis Weinstein in 1982. In a 2005 article, Weinstein wrote that the unexplained postpartum death of a woman who had hemolysis, abnormal liver function, thrombocytopenia, and hypoglycemia motivated him to review the medical literature and to compile information on similar women. He noted that cases with features of HELLP had been reported as early as 1954.
