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

Philosopher and playwright Jean-Paul Sartre staged his first play while he was imprisoned in a POW camp.

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."

Sartre eventually denounced communism

The French philosopher was a long-time ardent supporter of communism and the USSR. He finally spoke out against the movement with the 1956 Soviet invasion of Hungary, saying that the move was "made possible by 12 years of terror and imbecility."

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.

Novelist Richard Wright joined the existentialists in Paris

The author of “Black Boy” and “Native Son” left the United States in 1946 to escape his home country’s racial inequality. In Paris, he explored existentialist ideas and spent time with Simone de Beauvoir and Jean-Paul Sartre. “The Outsider,” a novel he wrote while living in France, embraced many of the philosophy’s central themes.

Camus directed a Picasso-penned play

The show, called "Desire Caught by the Tail," was written by Picasso in 1941 while living in Nazi-occupied Paris. It was first staged in 1944, featuring several French intellectuals, including Albert Camus, who directed, as well as Jean-Paul Sartre and Simone de Beauvoir, who had starring roles.

Jean-Paul Sartre rejected his Nobel Prize in literature in 1964, believing it was antithetical to his role as an artist.

Jean-Paul Sartre believed 'existence precedes essence'

The existentialist figurehead argued that humans are not born with an identity or purpose; instead, they develop them throughout their lives. For Sartre, this meant making meaning for oneself rather than relying on authorities (like religion or government) to provide it.

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.

Sartre panned 'Citizen Kane'

Jean-Paul Sartre was primarily known for his philosophy, fiction, and drama, but he was also a critic. In 1945, he wrote a rather negative review of Orson Welles' "Citizen Kane," deriding Welles' decision to tell the story in the past tense, writing, "film in the past tense is the antithesis of cinema. Therefore 'Citizen Kane' is not cinema."

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.

Existentialist literature explores the philosophy's ideas

Existentialism isn't confined to philosophical texts. Some of the movement's figureheads, like Albert Camus and Jean-Paul Sartre, were also novelists. Christina Howells, Professor of French at the University of Oxford, suggests this is because existentialism, as a philosophy, requires human stories to be fully understood, and literature makes the experience of the human condition more present and immediate.

Sartre believed those who deny their own freedom are operating in 'bad faith'

In "Existentialism is a Humanism," Sartre argues that humans are "condemned to be free"—they are not confined to a divine fate, which means they must take the responsibility of creating their own destinies. Those who reject this freedom, by his estimation, are living in "bad faith."

Jean-Paul Sartre was amazed by American jazz

The French philosopher wrote about a 1947 trip to a New York jazz club as a transcendent experience, describing the magic of the relationship between performer and audience: "You shout, they shriek, they whistle, they are possessed, you are possessed."

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."

Champagne played a role in resisting the Nazis

When France surrendered to the Nazis in 1940, the invaders occupied the north. This was home to wine regions like Champagne and Bordeaux, which the Nazis were eager to loot. Winemakers took a stand by sheltering dissidents in their cellars, passing intelligence across borders, and even giving their lives to the cause.

Many writers considered 'existentialist' didn't identify with the term

“Existentialism” was first introduced in 1943 by philosopher Gabriel Marcel. Jean-Paul Sartre and Simone de Beauvoir readily adopted the term, but others, such as Albert Camus and Martin Heidegger, rejected it. Earlier philosophers, like Søren Kierkegaard and Friedrich Nietzsche, were long dead by the time the word was in vogue.

Sartre wrote an 8-hour screenplay for a Freud biopic

Sartre was hired to write the screenplay for what would eventually become John Huston's 1962 film "Freud: The Secret Passion," about the life of the psychoanalyst. Sartre, however, had trouble sticking to the parameters of Hollywood. An early draft was estimated to be five hours long. Rather than shortening it, as Huston suggested, Sartre extended it to eight hours and was eventually removed from the production.

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

A mescaline-induced hallucination stayed with Jean-Paul Sartre throughout his life

In 1935, Sartre was injected with mescaline, a psychedelic drug that was then used to treat alcoholism and depression, by his friend at the Hôpital Sainte-Anne in Paris. It was not a good trip: Sartre saw nightmarish crabs for days and suffered a mental breakdown. For the rest of his life, crustaceans like the ones he saw during the hallucination appeared in his works.

Simone de Beauvoir's lone play has mostly been overlooked

Although primarily known as a philosopher, Beauvoir wrote the play "The Useless Mouths," which debuted in Paris in November 1945. The work is about a government allowing "useless" citizens—women, children, the elderly—to starve during a food shortage. While it's not widely staged, some Beauvoir scholars believe it's a significant text that explores many of the existential themes she explores in her other work.

Sartre and de Beauvoir had an open romantic relationship

The two figureheads of existentialist thought were romantic partners, though they had a publicly open relationship and never lived together. As de Beauvoir says in the interview below, "third persons knew our relationship dwarfed any we could have with them."

Camus and Sartre had a public falling out over communism

The two were close friends, sometimes collaborating throughout the 1940s, but the release of Camus' 1951 book, "The Rebel," led to a schism over differing views on communism.

Sartre was an elaborate prankster as a student

After Charles Lindbergh completed his first solo transatlantic voyage in 1927, the French philosopher—then a student at Paris' École normale supérieure—called various newspapers to tell them the American pilot would be granted an honorary degree. Over 500 people showed up to find a Lindbergh lookalike Sartre had hired. "The public fell for it, and an old man even kissed his hand," Sartre later wrote.

Read Albert Camus' 'Myth of Sisyphus and Other Essays'

Camus' most famous work of nonfiction is this collection of philosophical essays. Perhaps the most resonant entry is the title essay, which reimagines the Greek myth of a man condemned to roll a boulder for all eternity. Rather than presenting the story as a cautionary tale about defying the gods, as the original myth intended, Camus considered Sisyphus an "absurd hero" for his actions and imagined him smiling as he endlessly toiled at his repetitive punishment.

Camus won the Nobel Prize in literature in 1957 for his philosophical essays and fiction

The philosopher and novelist was one of the youngest writers to win the award, at just 44. In his acceptance speech, he spoke on the role of an artist in a world that seemed increasingly bleak. "Each generation doubtless feels called upon to reform the world," he said. "Mine knows that it will not reform it, but its task is perhaps even greater. It consists in preventing the world from destroying itself."

Sartre's 1980 funeral attracted a massive crowd

The legendary existentialist died April 15, 1980. A week later, mourners packed the streets of Paris to pay tribute. Estimates suggest that between 20,000 and 50,000 people were in attendance. In the Associated Press footage below, you can watch them following the hearse from the hospital where the thinker died to his resting place in Montparnasse Cemetery.

Sartre and de Beauvoir's literary journal was named after a Charlie Chaplin movie

The couple founded the magazine Les Temps Modernes in 1945 and it quickly became essential reading for French intellectuals. Its name came from "Modern Times," Charlie Chaplin's 1936 movie that satirized the industrial revolution's dehumanizing effects.

An existentialist reading list

If you’re looking for a starting point for diving into existentialist thought, this is a great resource. Its titles are not exactly obscure—Albert Camus’ “The Stranger,” Franz Kafka’s “The Trial,” and Søren Kierkegaard’s “Either/Or” are among the most famous works in Western literature—but the list provides some digestible context for each text, which will help you decide the best place to begin your journey.

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."

Existentialism has been used as a therapeutic tool, with 2 Swiss psychiatrists pioneering the philosophy's concepts to help patients navigate their issues.

One of Sartre and de Beauvoir's lovers accused them of exploitation

The philosophical duo's open relationship sometimes included shared partners, including de Beauvoir's students. One of those students, Bianca Lamblin, wrote a book, "A Disgraceful Affair," about the experience and characterized it as sexual exploitation.

Camus was once a communist, but eventually disavowed the ideology

The writer belonged to the French Communist Party and the Algerian Communist Party in the mid-1930s, but he was eventually expelled for refusing to downplay objections to French colonialism. By the time he published "The Rebel," he was vocally anti-communist, believing it was a utopian ideology that often relied on violence.

Jean-Paul Sartre famously wrote that 'Hell is—other people'

The line appears toward the end of the play "No Exit." One character, realizing that he's confined to live out the rest of his days with the play's other two characters, exclaims, "There's no need for red-hot pokers. Hell is—other people!"

Existentialism inspired Franklin Roosevelt and Martin Luther King Jr.

The Danish philosopher, sometimes called “the father of existentialism,” believed that individuals needed to resist the temptation of conformity and instead discover their authentic selves. His work became remarkably influential in the 20th century. In 1944, Roosevelt said that reading Kierkegaard made him understand how the Nazis could’ve enacted so much violence. In 1959, King wrote that existentialism was “especially meaningful for our time.”

Voltaire's writing sent him into exile

In 1717, the writer's satirical poem "La Henriade" landed him in prison for a year. By 1726, the French government's distaste for his work caused him to leave the country for England, though he returned a few years later. That would be short-lived: In 1734, his "Lettres Philosophiques" sent him packing again, moving to Champagne, then Berlin, then Switzerland, before finally returning to Paris in 1778.

The man behind the dark novel abandoned on the floor of the Bastille

As tensions rose in the days before the French Revolution of 1789, Donatien Alphonse François attempted to fan the flames by shouting at passersby about false horrors happening inside the Bastille where he was imprisoned. This 39-minute podcast...

Disillusioned mid-century playwrights, such as Samuel Beckett and Eugène Ionesco, brought existentialist ideas to the stage through the Theater of the Absurd.

Dreaming under the Nazi Regime

Days after Hitler seized power, a man told psychoanalyst Charlotte Beradt that he had dreamed of being forced to raise his arm in a Nazi salute ("It took me half an hour to get my arm up, inch by inch"). Beradt recorded this dream and many others so they "might one day serve as evidence." This is an English translation of her work, "The Third Reich of Dreams."

Scholars trace existential anxiety back to early Hebrew scriptures

Paul Megna, a scholar of literature and philosophy, notes that the existentialist ideas of Kierkegaard (and, to a lesser extent, Sarte and Camus) had their roots in much earlier texts, which posited that "fear of the Lord" was "the beginning of wisdom."

A theater group staged 'Waiting for Godot' at San Quentin prison in 1957

The play, about being stuck, resonated with inmates. Critics noted that the incarcerated audience empathized with its hopeless characters much more than those at the show's North American premiere in Miami, who'd walked out in disgust.

Albert Camus' 'The Fall' encourages readers to live without illusions

The writer's final complete novel is a series of dramatic monologues from Jean-Baptiste Clamence, who tries to explain to a stranger the sound of laughter that began following him. As the "Philosophize This!" podcast argues, the book is Camus' attempt at wrestling with some of the thornier aspects of existentialism in a form that's more digestible than a dense philosophical tome.

Camus' books are largely ignored in Algerian schools

The writer was born in Algiers, wrote fondly of his home, and is perhaps the most well-known Algerian-born writer of all time, but his works are no longer taught. In 2010, a series of events to commemorate the 50th anniversary of his death was not permitted by the authorities. Scholars say that's because Camus believed the North African country should remain a French colony; after it gained independence in 1962, Camus' work fell out of fashion.

Simone de Beauvoir's 'The Second Sex' merged existentialism with feminism

De Beauvoir’s 1949 philosophical treatise criticized patriarchy and its negative impact on women. She argued that gender differences were mainly due to socialization rather than innate qualities, writing that “one is not born, but rather becomes, a woman.” In turn, de Beauvoir believed women should refuse predetermined gender roles and instead define themselves, echoing a key tenet of existentialism.

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. (Some users may experience a paywall.)

In the 1950s, the Vatican included Simone de Beauvoir's 'The Second Sex' on its list of forbidden books.

During the COVID-19 pandemic, readers returned to Camus' 'The Plague'

The 1947 novel, about a city in Algeria that enacts a city-wide quarantine to battle a deadly outbreak, captured readers' attention in the early months of 2020. In the UK, over 2,000 copies of the book were sold in March of that year, over six times what it had sold the month before.

Camus was born in Algeria, but was considered French

French Algeria was segregated between Arabs and "pieds-noirs," which was then a derogatory name for the million-plus Europeans living in the North African country. Camus was one of the latter, and throughout his life, he argued for political rights for Arabs while also believing the country should remain part of France. Pieds-noirs largely fled the country after it gained independence in 1962.

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.’”

Samuel Beckett's 'Waiting for Godot' dramatizes existential absurdity

The play, originally staged in 1953, is notorious for its lack of action. For the most part, its two principal characters, Vladimir and Estragon, spend the majority of the play wondering whether a mysterious Godot will ever appear. By the end, Godot has still not arrived, yet Vladimir and Estragon do not move, a choice that reflects the existential notion that humans often hope in vain for meaning that does not exist.
