Deathwatch (French: Haute Surveillance ) is a play written by Jean Genet in 1947, performed for the first time in Paris at the Théâtre des Mathurins in February 1949 under the direction of Jean Marchat.
The Miracle of the Rose (French: "Miracle de la rose" ) is a 1946 book by Jean Genet about experiences as a detainee in Mettray Penal Colony and Fontevrault prison - although there is no direct evidence of Genet ever having been imprisoned in the latter establishment.
 This autobiographical work has a non-linear structure: stories from Genet's adolescence are mixed in with his experiences as a thirty-year-old man at Fontevrault prison.
 At Mettray, Genet describes homosexual erotic desires for his fellow adolescent detainees.
 There is also a fantastical dimension to the narrative, particularly in Fontevrault passages concerning a prisoner called Harcamone who is condemned to death for murder.
 Genet idolises Harcamone and writes poetically about the rare occasions on which he catches a glimpse of this character.
 Genet was detained in Mettray Penal Colony between 2 September 1926 and 1 March 1929, after which, at the age of 18, he joined the Foreign Legion.
Jean Maurice Eugène Clément Cocteau (] ; 5 July 1889 – 11 October 1963) was a French writer, designer, playwright, artist and filmmaker.

 His circle of associates, friends and lovers included Kenneth Anger, Pablo Picasso, Gertrude Stein, Jean Hugo, Jean Marais, Henri Bernstein, Yul Brynner, Marlene Dietrich, Coco Chanel, Erik Satie, Albert Gleizes, Igor Stravinsky, Marie Laurencin, María Félix, Édith Piaf, Panama Al Brown, Colette, Jean Genet, and Raymond Radiguet.

"The Jean Genie" is a song by David Bowie, originally released as a single in November 1972.
 According to Bowie, it was "a smorgasbord of imagined Americana", with a protagonist inspired by Iggy Pop, and the title being an allusion to author Jean Genet.
 One of Bowie's most famous tracks, it was the lead single for the album "Aladdin Sane" (1973).
 Promoted with a film clip featuring Andy Warhol associate Cyrinda Foxe, it peaked at No. 2 on the UK Singles chart.
Saint Genet, Actor and Martyr (French: "Saint Genet, comédien et martyr" ) is a book by the French philosopher Jean-Paul Sartre about the writer Jean Genet especially on his "The Thief's Journal".
 It was first published in 1952.
 Sartre described it as an attempt "to prove that genius is not a gift but the way out that one invents in desperate cases."
 Sartre also based his character Goetz in his play "The Devil and the Good Lord" (1951) on his analysis of Genet's psychology and morality.
 Sartre has been credited by David M. Halperin with providing, "a brilliant, subtle, and thoroughgoing study of the unique subjectivity and gender positioning of gay men".
Funeral Rites ("Pompes funèbres") is a 1948 novel by Jean Genet.
 It is a story of love and betrayal across political divides, written this time for the narrator's lover, Jean Decarnin, killed by the Germans in World War II.
Genet's mother was a prostitute who raised him for the first seven months of his life before putting him up for adoption.
 Thereafter Genet was raised in the provincial town of Alligny-en-Morvan, in the Nièvre department of central France.
 His foster family was headed by a carpenter and, according to Edmund White's biography, was loving and attentive.
 While he received excellent grades in school, his childhood involved a series of attempts at running away and incidents of petty theft.
Plaça de Jean Genet is a small, triangle-shaped square in Barcelona (the capital of Catalonia in Spain).
 It's located in the southern side of El Raval, by the port and Avinguda de les Drassanes and the Catalan Gothic buildings of the Royal Shipyard, in the district of Ciutat Vella.
 Its main feature is the functionalist high-rise which hosts the local Official School of Languages.
 It's named after French author Jean Genet who resided in the city for a time and whose novel "The Thief's Journal" takes place in the poverty-stricken alleys of Raval.
