Whipple of Whipple's Triad.

Allen Oldfather (A. O.) Whipple (1881-1963) is renowned for giving rise to two medical eponyms: Whipple's Triad, for the diagnostic criteria in hypoglycemia, and Whipple's procedure, for the cephalic duodenopancreatectomy. Notably, A. O. Whipple's life coincided with that of the unrelated George Hoyt Whipple, who is credited with the third eponymous Whipple in medicine - Whipple's disease, or intestinal lipodystrophy. Nearly a century after its first description, Whipple's Triad continues to be a valuable tool, comprising a set of symptoms and laboratory data that raise the clinical suspicion of hypoglycemia resulting from endogenous hyperinsulinism.
