I whanau a Ernest Miller Hemingway i te Hōngongoi 21, 1899, i Oak Park, Illinois, he taone o Chicago. Ko tona papa, ko Clarence Edmonds Hemingway, he taote, ko tona whaea, ko Grace Hall Hemingway, he kaiwaiata. I whanau nga tamariki tokorua ki te whare moenga e whitu i roto i te rohe o Oak Park, he hapori parakore e kii ana a Frank Lloyd Wright, "He maha nga hahi mo te maha o nga taangata pai ki te haere". I muri i to raua marena, i noho a Clarence raua ko Grace Hemingway ki te papa o Grace, a Ernest Hall, te ingoa o ta raua tama tuatahi. I muri mai, ka kii a Ernest Hemingway kaore ia i pai ki tona ingoa, i "whakapono ia ki te maamaa, ahakoa te maamaa o te takaro a Oscar Wilde The Importance of Being Earnest".
Ko te tau 1899
