The Sun Also Rises [SEP] Background
He finished the draft on 21 September 1925, writing a foreword the following weekend and changing the title to "The Lost Generation". A few months later, in December 1925, Hemingway and his wife spent the winter in Schruns, Austria, where he began revising the manuscript extensively. Pauline Pfeiffer joined them in January, and—against Hadley's advice—urged him to sign a contract with Scribner's. Hemingway left Austria for a quick trip to New York to meet with the publishers, and on his return, during a stop in Paris, began an affair with Pauline. He returned to Schruns to finish the revisions in March.
