Patrick Hemingway, the second son of the novelist Ernest Hemingway, who became a safari guide and big-game hunter in Africa, completed a book his father had started and published a volume of their letters, died on Tuesday at his home in Bozeman, Mont. He was 97.

His death was confirmed by Bettina Klinger, a representative of the Hemingway family.

Of Hemingway’s three sons, Patrick came closest to simulating, though hardly emulating, his father, who won the 1954 Nobel Prize in Literature, the 1953 Pulitzer Prize for fiction, and renown for novels and short stories drawn from his life as a World War I ambulance driver, a journalist in the Spanish Civil War and a man obsessed with bullfighting, deep-sea fishing and women who were as challenging as he was.

Hemingway’s first son, Jack, was an avid fly fisherman who fished in Europe between battles in World War II. He had difficulty finding a postwar career until he became Idaho’s fish and game commissioner in the 1970s. He died in 2000.

Hemingway’s third child, Gloria Hemingway, was a physician who struggled with alcohol abuse. She wrote a memoir, “Papa” (1976), before undergoing transition surgery later in life. She died in 2001.

Affectionately known within the family as Mouse, Patrick was born to Hemingway’s second wife, Pauline Pfeiffer, a wealthy Roman Catholic American journalist who became Vogue’s correspondent in Paris. They married there in 1927 after a whirlwind romance and Hemingway’s conversion to Catholicism.
