Frances Cleveland (July 21, 1864 – October 29, 1947) was the first lady of the United States from 1886 to 1889 and again from 1893 to 1897, as the wife of President Grover Cleveland. She met him while an infant, as he was a friend, and later the executor, of her father, Oscar Folsom. Grover settled Oscar's debts and provided for Frances. She graduated from Wells College, then married Grover while he was president. When he lost reelection in 1888, they went into private life for four years, returning when he was elected again in 1892. Much of her time during Grover's second term was dedicated to their children. They had five; four survived to adulthood. Frances Cleveland served on the Wells College board, supported women's education, and organized kindergartens. Grover died in 1908, and she married Thomas J. Preston Jr. in 1913. During World War I, she advocated military preparedness. She died in 1947 and was buried alongside Grover Cleveland in Princeton Cemetery. This portrait photograph of Frances Cleveland was taken in 1886.

Ernest Hemingway (July 21, 1899 – July 2, 1961) was an American novelist, short-story writer and journalist. Known for an economical, understated style that significantly influenced later 20th-century writers, he is often romanticized for his adventurous lifestyle, and outspoken and blunt public image. Most of Hemingway's works were published between the mid-1920s and mid-1950s; these included seven novels, six short-story collections and two non-fiction works. His debut novel The Sun Also Rises was published in 1926. His wartime experiences as an ambulance driver on the Italian Front in World War I formed the basis for his 1929 novel A Farewell to Arms, and he drew on his experience as a journalist in the Spanish Civil War for his 1940 novel For Whom the Bell Tolls. Hemingway was with Allied troops as a journalist at the Normandy landings and the liberation of Paris. He was awarded the 1954 Nobel Prize in Literature. (Full article...)
