later be known as the Little White House. Franklin D. Roosevelt visited the Florida Keys many times, beginning in 1917. Harry S. Truman visited Key West for a total of 175 days on 11 visits during his presidency and visited five times after he left office. His first visit was in 1946. The Little White House and Truman Annex take their names from his frequent and well-documented visits. The residence is also known as the Winter White House as Truman stayed there mostly in the winter months, and used it for official business such as the Truman Doctrine. Dwight D. Eisenhower stayed at the Little White House following a heart attack in 1955. John F. Kennedy visited Key West in March 1961, and in November 1962, a month after the resolution of the Cuban Missile Crisis. Jimmy Carter visited the Little White House twice with his family after he had left office, in 1996 and 2007. Ernest Hemingway house Legend has it that Ernest Hemingway wrote part of A Farewell to Arms while living above the showroom of a Key West Ford dealership at 314 Simonton Street while awaiting delivery of a Ford Model A roadster purchased by the uncle of his wife Pauline in 1928. Hardware store owner Charles Thompson introduced him to deep-sea fishing. Among the group who went fishing was Joe Russell (also known as Sloppy Joe). Russell was reportedly the model for Freddy in To Have and Have Not. The group had nicknames for each other, and Hemingway wound up with "Papa". Pauline's rich uncle Gus Pfeiffer bought the 907 Whitehead Street house in 1931 as a wedding present. The Hemingways installed a swimming pool for $20,000 in 1937–38 (equivalent to about $ in ). The unexpectedly high cost prompted Hemingway to put a penny in the wet cement of the patio, saying, "Here, take the last penny I've got!" The penny is at the north end of the pool. During his stay he wrote or worked on Death in the Afternoon, For Whom the Bell Tolls, The Snows of Kilimanjaro, and The Short Happy Life of Francis Macomber. He used Depression-era Key West as one of the locations in To Have and Have Not—his only novel with scenes that occur in the United States. The six- or seven-toed polydactyl cats descended from Hemingway's original pet "Snowball" still live on the grounds and are cared for
