JD Salinger served in World War II while working on a draft of his most famous novel, 'The Catcher in the Rye.'

JD Salinger, author of 'The Catcher in the Rye,' stopped publishing in 1965, though he continued writing until his death in 2010, with some estimates saying he completed 5 additional books.

Disney tried to adapt 'The Catcher in the Rye' for the screen, with plans to reimagine it as an animated film about German shepherds.

Sartre spent his time in the French Army working on a novel

The writer's physical limitations (including partial blindness and balance issues) prohibited him from serving on the front lines. Instead, he worked as a military meteorologist. The job was not very demanding, so he spent most of his time writing. He told Simone de Beauvoir it was "extremely peaceful work; indeed I cannot think of any branch of the services that has a quieter, more poetic job."

A book series aimed at World War II soldiers helped popularize works like 'The Great Gatsby' and 'Of Mice and Men.'

Jean-Paul Sartre worked on 'Being and Nothingness' while a prisoner of war

The Nazis invaded France in May 1940. Sartre, as a member of the French Army, was taken prisoner that June. While he was in captivity, he studied Martin Heidegger and worked on "Being and Nothingness," one of his most famous philosophical works.

Camus edited an underground newspaper during World War II

The paper, called "Combat," was aligned with the French Resistance fighting against the Nazi occupation. Like his fiction, his journalism was clear-eyed: When Hiroshima and Nagaski were bombed, he criticized the many writers impressed with the destruction, writing, "our technical civilization has just reached its greatest level of savagery."

John Steinbeck spent 6 years studying at Stanford, but never earned a degree.

Sartre staged his first play in a POW camp

While imprisoned by the Nazis, the French writer was given permission to write and produce a Christmas show for 15,000 of his fellow POWs. He took the opportunity to produce "Bariona, or the Son of Thunder," a Nativity play that subtly criticized his captors without arousing their suspicions.

Camus was influenced by American culture, especially literature and jazz

He loved the work of writers like William Faulker and Ernest Hemingway, and loved drinking whiskey and listening to jazz. He also admired the actor Humphrey Bogart and his striking performance in the noir classic "The Big Sleep." He was delighted when his wife gave him a Burberry raincoat, thinking it made him look more like Bogart.

Kurt Vonnegut's 'Cat's Cradle' was inspired by the bombing of Hiroshima

The writer fought in World War II and witnessed the firebombing of Dresden, which he recounted in 1969's satirical "Slaughterhouse Five." Six years earlier, though, he wrote about the bombing of Hiroshima in "Cat's Cradle," channeling some of the horror he witnessed in Dresden to write about the dropping of the atomic bomb.

Camus contracted tuberculosis as a teenager

There was still little understanding of treatment for the disease at the time; for most people, a tuberculosis diagnosis was a death sentence. The 17-year-old Camus was quarantined in his uncle's house, where he grew into an avid reader. Scholars note that the experience would inform his later work, including his 1947 novel "The Plague."

Mel Brooks served in World War II, including a stint clearing landmines at the Battle of the Bulge.

'The fact is always obvious much too late, but the most singular difference between happiness and joy is that happiness is a solid and joy a liquid.'

-Writer J.D. Salinger (1919-2010)

Kurt Vonnegut's satire embraced dark humor

Books like "Cat’s Cradle" and "Slaughterhouse Five" satirized the international appetite for war, which the 20th-century writer found both horrifying and hilarious. It’s a combination that some called “gallows humor,” a classification Vonnegut himself remembered Sigmund Freud describing. “One of the examples Freud gives is a man about to be hanged,” Vonnegut once recalled, “and the hangman says, ‘Do you have anything to say?’ The condemned man replies, ‘Not at this time.’”

Penicillin supplies were ready for every wounded soldier on D-Day

By June 1944, Allied stockpiles included 2.3 million doses of penicillin—enough to ensure that every soldier wounded during the pivotal Normandy landings could receive treatment.

‘Dispatches’ by Michael Herr pushed the boundaries of war journalism

His account detailed the experiences of soldiers, while also expressing uncertainty about the meaning of the war.

Camus and Sartre admired each other's work before becoming friends

The two writers, who would later be considered two of the biggest names associated with existentialism, wrote positive reviews of each others' early work, with Camus praising Sartre's novel "Nausea" and story collection "The Wall" and, later, Sartre favorably compared Camus' "The Stranger" to Franz Kafka and Ernest Hemingway. Still, their reviews included some critiques, hinting at the larger disagreements that would come much later.

See what it was like to live in the United States during World War II

In America, life was transformed by total war: sixteen million service members left civilian life, while massive industrial production demanded labor. Women, minorities, and teens filled factories, fueling boomtown growth and breaking social barriers. Simultaneously, rationing, recycling drives, Victory Gardens, ration stamps, blackout drills, and war bond campaigns permeated daily routines.

The FBI kept tabs on Camus and Sartre

Jean-Paul Sartre worked as an American correspondent for Combat, the newspaper edited by Albert Camus. While he was in the States, J. Edgar Hoover's FBI kept tabs on him, concerned that Combat was publishing unfavorable portrayals of the US.

'The Stranger' remains a popular novel for teenagers

Camus' book's themes—alienation, transgression, and existentialism—continue to resonate with adolescent reader. That's also true of other popular teenage touchstones, like Aldous Huxley's "Brave New World," George Orwell's "Nineteen Eighty-Four," and Sylvia Plath's "The Bell Jar," which are still widely read—and assigned by high school teachers.

Sartre admired American novelist William Faulkner

In addition to writing philosophy and fiction, Jean-Paul Sartre was also a literary critic. His 1939 essay on Faulkner's "The Sound and the Fury" focused on the way the American novelist commented on time, favorably comparing him to Marcel Proust. Ultimately, Sartre argues Faulkner's "despair" about a "closed future" is a result of the "social conditions of our present life." Ever the existentialist, though, Sartre suggests this reality is something that should inspire rather than depress.

John Hersey’s ‘Hiroshima’ focused on the stories of atomic bomb victims

The nonfiction book is considered one of the earliest pieces of New Journalism and an arresting case against nuclear warfare. Describing the pain, wounds and trauma of six ordinary citizens, “Hiroshima” played a powerful role in American perception of the war by focusing on its human toll.

Kurt Vonnegut's letter to the school board that banned his book

In 1973, a high school English teacher in North Dakota taught Kurt Vonnegut's "Slaughterhouse-Five," the classic time-hopping novel about World War II and the bombing of Dresden.
