Te Rangi Hīroa, also known as Sir Peter Henry Buck KCMG DSO (ca. October 1877 – 1 December 1951), was a prominent member of the Ngāti Mutunga Māori iwi. He was a doctor, military leader, health administrator, politician, anthropologist and museum director.He was born in Urenui, New Zealand, the only child of William Henry Buck. He was raised by William and his wife Ngarongo-ki-tua, though she was not his biological mother. According to local custom, when the couple found themselves unable to have children, one of Ngarongo's relatives, Rina, became part of the household and produced a child for the couple. Rina died soon after her child was born, and Ngarongo raised Peter as her own. He claimed to have been born in 1880, but it is more likely that an entry in the primary school register pointing to October 1877 is correct. Wikipedia
