Hemingway was born on July 21, 1899 in Oak Park, Illinois, a suburb of Chicago. His father Clarence Edmonds Hemingway was a physician, and his mother, Grace Hall-Hemingway, was a musician.

When Clarence and Grace Hemingway married in 1896, they moved in with Grace's father, Ernest Hall, after whom they named their first son. Hemingway claimed to dislike his name, which he "associated with the naive, even foolish hero of Oscar Wilde's play The Importance of Being Earnest".
