American poet, writer and Librarian of Congress, Archibald MacLeish (1892-1982) married Ada Taylor Hitchcock in June 1918. Moving to the French capital in September 1923, Archibald and Ada MacLeish hoped to cultivate successful careers as a poet and a professional singer respectively. It was whilst in Paris that they met Hemingway, beginning what has been described as 'a long and close though difficult friendship.' Archibald MacLeish was awarded three Pulitzer Prizes for his work.
Gerald (1888-1964) and Sara (1883-1975) Murphy were wealthy expatriates who had married in New York City and moved to Paris in 1921. Once there, Gerald took up painting, and it was through his art that he started to make connections with the likes of Hemingway and Fitzgerald. Later, the couple moved to the French Riviera, where they frequently entertained large circles of their artistic and literary friends; it was for these associations that they were most noted.
The characters Nicole and Dick Diver in Fitzgerald's novel Tender is the Night are thought to be based on the pair, and many similarities are also drawn between them and Hemingway's couple in The Garden of Eden.
