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

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 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.

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.

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.

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

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 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.

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.

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.

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.

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.

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."

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.

Simone de Beauvoir, the influential feminist and existentialist philosopher, was a serious hiker.

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.

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."

Marina Abramović and Ulay worked and lived together for 12 years

Their infamous body of work, known as “The Relation Works,” aimed to explore the dynamics between male and female partnerships, exposing power imbalances and frustration. (This resource contains some artistic nudity.)

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.

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.

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.

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.

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.

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

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."

Salvador Dalí and Coco Chanel bonded over art and fashion

In the late 1930s, Chanel hosted the eccentric artist to like and work in her home. Despite their differing styles, the two icons collaborated, and Chanel even inspired Dalí to mimic her perfume in his artwork.

Inside the Sarah Lawrence College sex cult scandal

In late 2010, a middle-aged man, freshly released from prison, moved into his daughter's college dorm and created a group that had all the hallmarks of a cult. Over the decade that followed, he extorted millions of dollars from vulnerable young adults through violence, psychological torture, and forced sex work. Authorities credited his arrest to a magazine article published in 2019 detailing victims' allegations.

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.

Mary Cassatt and Edgar Degas both influenced each other's work and challenged one another to try new techniques in their painting, though their relationship eventually soured for unclear reasons.

In 1922, Zelda Fitzgerald was commissioned to write a satirical review of her husband's latest novel

The review of "The Beautiful and the Damned" might have been comedic, but it was also illuminating, allowing Zelda to acknowledge her husband's tendency to use material from her diaries in his fiction and interrogate the way female characters were often portrayed in novels written by men.

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 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.

James Beard and Julia Child were close friends and collaborators

The duo met when she was promoting her seminal book “Mastering the Art of French Cooking” in 1961. They quickly bonded, even referring to themselves as “Jiji,” a combination of Julia and Jim. Child, though, was initially prejudiced against Beard for being openly gay, which was rarer at that time.

O’Connor shared lengthy, intimate letters with Betty Hester, a recluse

When O’Connor’s private letters were released in “The Habit of Being,” readers wondered about the identity of “A,” who had an intimate (possibly romantic) relationship with the writer. Decades later, “A” was revealed to be Betty Hester, a reclusive file clerk. Scholars still debate whether the two were romantically involved.

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

Why Orwell called Dalí a 'disgusting human being'

Writer George Orwell took offense at the disturbing actions described in Dalí's salacious autobiography "The Secret Life of Salvador Dalí." In a 1944 essay, Orwell described the cruelty and moral degradation of Dalí—while also admitting the artist's undeniable talent.

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!"

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 frenemies who shaped Modern Art

Matisse and Picasso are two of the biggest names in Modern Art, with works that redefined the possibilities of painting in the 20th century. While they were often cast as rivals, this Artnet article highlights their more complicated relationship, which was somewhere between a friendship, a mentorship, and an ongoing competition.

Existentialism is a loosely defined philosophy that encouraged authentic living

The writers and thinkers often characterized as “existentialist” sometimes contradict one another. Considering that, boiling the philosophy down to a set of tenets can be difficult. Generally, those associated with existentialism were inspired by the 19th-century works of Søren Kierkegaard and Friedrich Nietzsche, and they believed that individuals needed to defy conformity and define the meaning of life for themselves.

Picasso’s legacy is often intertwined with his personal relationships

Family revelations and quotes show the legendary artist as both tender and cruel, and his fame and romantic advances sometimes had disastrous effects on those around him.

30,000 men known as the 'League of Broke Husbands' once protested Dior's luxury fashion designs

In the 1940s, these men living in post-war France were angry about the waste and cost of the fabric needed to make its luxury clothing. Today, Dior is owned by luxury conglomerate LVMH.

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.

A profile of Dickinson's ambiguous but close relationship with Susan Gilbert

Gilbert met Dickinson in 1850, and the two women quickly became very close, with Dickinson often pining for Gilbert in letters. In this essay, critic Maria Popova calls the relationship "beautiful, heartbreaking, unclassifiable," and details how it came to inspire Dickinson's writing, even after Gilbert married Dickinson's brother.

In 1969, a group of reporters wrote an intentionally bad and salacious novel under a pen name to prove that sex sells more than quality. It sold 20,000 copies within a few months and spent 13 weeks on the New York Times Bestseller list.

Dorothea Lange and her economist husband sought to document American poverty through collaborative works.

Salvador Dalí idolized Freud but was disappointed after they met

Sigmund Freud's writings on dreams and the unconscious profoundly influenced Dalí and his work, and the artist came to idolize the Austrian psychoanalyst. When they met, Freud viewed Dalí as an odd curiosity, and the artist came away disappointed, significantly lowering his opinion of the psychoanalyst.

A Camus scholar believes 'The Stranger' is often misread as a role model

The writer and philosopher Jonathan Rée notes that part of the reason why the book was so popular was that it was an easy pick for students learning French to translate. What's often lost in translation, though, is that the book's narrator, Meursault, who murders a man, is not intended to be a role model.

Basquiat and Warhol were friends and collaborators before a bitter falling out

The two men were tight, but they also offered what the other lacked in the art world: Basquiat inspired Warhol, and Warhol gave Basquiat art-world credibility. They began working together, producing 160 collaborative works between 1983 and 1985. A 1985 exhibition of their joint works was a massive flop, though, and the friendship never recovered.

Poet Robert Lowell was once convinced communists were invading an artist colony

In 1949, the Pulitzer winner accused Elizabeth Ames, director of the Yaddo artist colony in Saratoga Springs, New York, of colluding with Agnes Smedley, a journalist who'd been staying on the property for years and who was working on a project sympathetic to communist causes.
