The man wrote, wherever he was.
Hemingway's typewriter at Key West, Florida - Stefan Möding, copyright
Ernest Hemingway often wrote standing up at his typewriter. Obviously, here in Key West, he wrote sitting down. At every home, it appears, he had a typewriter.
In Key West, early on in an apartment near the Ford dealership, where they awaited the delivery of the Ford purchased for Hemingway and his wife Pauline, by Pauline’s Uncle Gus, Hemingway wrote most of A Farewell to Arms, published in 1929.
The house was purchased later. I can’t tell — some say he used here a Royal Quiet DeLuxe.
Pauline and Hemingway divorced in 1939.
