Ginevra King was born in 1898 into a wealthy Chicago family and grew up in Lake Forest, Illinois. In January 1915, home from school, she met F. Scott Fitzgerald, then a Princeton undergraduate. The romance ran for roughly two years, conducted largely by letter, and ended before he left for the army.
She married William Mitchell in 1918 and remained in the Chicago society she had been born into. Fitzgerald returned to her for the rest of his working life: elements of Ginevra King appear in Isabelle Borgé in This Side of Paradise, Judy Jones in “Winter Dreams,” and Daisy Buchanan in The Great Gatsby. He told his daughter that Ginevra was the first girl he ever loved.
