John Hadley Nicanor Hemingway (October 10, 1923 – December 1, 2000) was a Canadian-American fly fisherman, conservationist, and writer. He was the son of American novelist and Nobel Prize-laureate Ernest Hemingway. Early life Jack Hemingway was born in Toronto, Ontario, Canada, the only child of American writer Ernest Hemingway and his first wife Hadley Richardson. He later gained two half-brothers, Patrick and Gregory/Gloria, from Hemingway's marriage to Pauline Pfeiffer. Throughout his life, Jack was considered by many to bear a strong physical resemblance to his father, but was more like his mother in temperament: "good-natured and even-tempered, and not particularly driven". He was named for his mother, and for the Spanish matador Nicanor Villalta y Serrés, whom his father admired. Gertrude Stein and Alice B. Toklas were his godparents. Nicknamed Bumby as a toddler by his mother "because of his plump teddy-bear qualities", he spent his early years in Paris and the Austrian Alps. College, military service, early post-war career Hemingway attended the University of Montana and Dartmouth College, but never graduated, instead enlisting in the U.S. Army after the attack on Pearl Harbor in 1941. Known for his sense of humor, in late 1943 at Camp Shanks near Orangeburg, New York, he overheard two older men (one of whom he recognized) in a bar arguing over who was the better writer, Ernest Hemingway or William Faulkner. Jack interrupted, and said in his opinion, there was "a writer that was a better storyteller than either Hemingway or Faulkner – Maurice Walsh". One of the men said, "'I am Maurice Walsh," to which Hemingway responded, "I'm Jack Hemingway ... pleased to meet you." Assigned overseas to France in 1944, he started as a military police officer commanding a special unit of black soldiers, and later obtained a transfer into the Office of Strategic Services (OSS), the newly formed U.S. wartime intelligence agency that evolved into the CIA after the war. As a French-speaking First Lieutenant with the OSS, he worked with the French Resistance. Characteristic of his sense of daring, he parachuted into occupied France with his fly rod, reel and flies, and was almost captured by a German patrol while fishing after his first mission. While on a leave in Algiers, he met with his father's third wife, Martha Gellhorn, whom Jack called his "favorite other mother", who was on her way to Italy to work as a war correspondent
