Jean Buridan (in Latin, Johannes Buridanus) (ca. 1300 – after 1358) was a French priest. He developed the concept of impetus, the first step toward the modern concept of inertia, and an important development in the history of medieval science. His name is most familiar through the thought experiment known as Buridan's ass (a thought experiment which does not appear in his extant writings).

Born, most probably, in Béthune, France, Buridan studied and later taught at the University of Paris. Apocryphal stories abound about his reputed amorous affairs and adventures which are enough to show that he enjoyed a reputation as a glamorous and mysterious figure in Paris life. In particular, a rumour held that he was sentenced to be thrown in a sack into the River Seine, but was ultimately saved through the ingenuity of a student. François Villon alludes to this in his famous poem Ballade des Dames du Temps Jadis. Buridan also seems to have had an unusual facility for attracting academic funding which suggests that he was indeed a charismatic figure.

Eric Arthur Blair (25 June 1903 – 21 January 1950), better known by his pen name George Orwell, was an English novelist and journalist. His work is marked by keen intelligence and wit, a profound awareness of social injustice, an intense opposition to totalitarianism, a passion for clarity in language and a belief in democratic socialism.

Considered perhaps the 20th century's best chronicler of English culture, Orwell wrote literary criticism, poetry, fiction and polemical journalism. He is best known for the dystopian novel Nineteen Eighty-Four (1949) and the allegorical novella Animal Farm (1945), which together have sold more copies than any two books by any other 20th-century author. His book Homage to Catalonia (1938), an account of his experiences in the Spanish Civil War, is widely acclaimed, as are his numerous essays on politics, literature, language and culture. In 2008, The Times ranked him second on a list of "The 50 greatest British writers since 1945".

Orwell's influence on popular and political culture endures, and several of his neologisms, along with the term Orwellian—a byword for totalitarian or manipulative social practices—have entered the vernacular.

Louis Armstrong (August 4, 1901 – July 6, 1971), nicknamed Satchmo or Pops, was an American jazz trumpeter and singer from New Orleans, Louisiana.

Coming to prominence in the 1920s as an "inventive" cornet and trumpet player, Armstrong was a foundational influence in jazz, shifting the music's focus from collective improvisation to solo performance. With his instantly recognizable deep and distinctive gravelly voice, Armstrong was also an influential singer, demonstrating great dexterity as an improviser, bending the lyrics and melody of a song for expressive purposes. He was also greatly skilled at scat singing (vocalizing using sounds and syllables instead of actual lyrics).

Renowned for his charismatic stage presence and voice almost as much as for his trumpet-playing, Armstrong's influence extends well beyond jazz music, and by the end of his career in the 1960s, he was widely regarded as a profound influence on popular music in general. Armstrong was one of the first truly popular African-American entertainers to "cross over," whose skin-color was secondary to his music in an America that was severely racially divided. It allowed him socially acceptable access to the upper echelons of American society that were highly restricted for a black man. While he rarely publicly politicized his race, often to the dismay of fellow African-Americans, he was privately a strong supporter of the Civil Rights movement in America.^{[citation needed]}

Georges Brassens (French pronunciation: [ʒɔʁʒ bʁasɛ̃s]), 22 October 1921 – 29 October 1981), was a French singer-songwriter and poet.

Brassens was born in Sète, a town in southern France near Montpellier. Now an iconic figure in France, he achieved fame through his elegant songs with their harmonically complex music for voice and guitar and articulate, diverse lyrics; indeed, he is considered one of France's most accomplished postwar poets. He has also set to music poems by both well-known and relatively obscure poets, including Louis Aragon (Il n'y a pas d'amour heureux), Victor Hugo (La Légende de la Nonne, Gastibelza), Jean Richepin, François Villon (La Ballade des Dames du Temps Jadis), and Guillaume Apollinaire, Antoine Pol (Les Passantes).

During World War II, he was forced by the Germans to work in a labor camp at a BMW aircraft engine plant in Basdorf near Berlin in Germany (March 1943). Here Brassens met some of his future friends, such as Pierre Onténiente, whom he called Gibraltar because he was "steady as a rock." They would later become close friends.

Robert de Flers (Robert Pellevé de La Motte-Ango, marquis de Flers) (25 November 1872, Pont-l'Évêque, Calvados – 30 July 1927, Vittel) was a French playwright, opera librettist, and journalist.

He entered the Lycée Condorcet in 1888 where he studied law with the initial ambition of entering diplomatic service. He met and befriended fellow student and writer Marcel Proust, and that relationship had a great influence upon him. Proust exposed Flers to art, literature, and music and his interests soon switched from law to writing, journalism, and literature. The two men enjoyed a lifelong friendship.

After completing his studies, he toured throughout Asia in the mid 1890s. The event inspired his earliest writings: the novel La Courtisane Taïa et son singe vert (1896), the short story Ilsée, princesse de Tripoli (1896), and the travel narrative Vers l’Orient (1897). Upon returning to Paris, he was approached by composer Edmond Audran to write the libretto for his operetta La reine des reines. The worked premiered on 14 October 1896 at the Théâtre de l'Eldorado in Strasbourg. His next libretto was for Gaston Serpette's vaudeville-operetta Shakspeare! which premiered at the Théâtre des Bouffes Parisiens on 23 November 1899.
