Hadley Richardson and Ernest Hemingway Are Divorced

Hemingway's marriage to Hadley broke down as he was writing and revising The Sun Also Rises.

In the spring of 1926, Hadley became aware of his affair with Pauline Pfeiffer, although she had endured Pauline's presence in Pamplona that July. However, on their return to Paris Hadley and Hemingway decided to separate, and Hadley formally requested a divorce in the fall. By November they had split their possessions, and Hadley accepted Hemingway's offer of the proceeds from The Sun Also Rises.

In April of that year [1926] Hadley would confront Ernest with her discovery of his affair with Pauline Pfeiffer. In May, when Ernest and Hadley were to begin an extended trip together to Spain for two months, then to the Antibes in August, and back home to the United States in September, a trip that might have saved their marriage, Bumby came down with whooping cough; the Hemingways were separated for several weeks during a crucial period in their relationship; and Pauline was brought back into their lives through a medical coincidence. As a result, before the year was out, Ernest and Hadley would file for divorce; he would contemplate suicide; he and Pauline would agree to marry and leave Paris, and his life would be forever changed.
