Felix Christian Klein (German: [klaɪn]; 25 April 1849 – 22 June 1925) was a German mathematician and mathematics educator, known for his work in group theory, complex analysis, non-Euclidean geometry, and the associations between geometry and group theory. His 1872 Erlangen program classified geometries by their basic symmetry groups and was an influential synthesis of much of the mathematics of the time.
During his tenure at the University of Göttingen, Klein was able to turn it into a center for mathematical and scientific research through the establishment of new lectures, professorships, and institutes. His seminars covered most areas of mathematics then known as well as their applications. Klein also devoted considerable time to mathematical instruction, and promoted mathematics education reform at all grade levels in Germany and abroad. He became the first president of the International Commission on Mathematical Instruction in 1908 at the Fourth International Congress of Mathematicians in Rome.

Sir Humphry Davy, 1st Baronet, (17 December 1778 – 29 May 1829) was a Cornish chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine. Davy also studied the forces involved in these separations, inventing the new field of electrochemistry. Davy is also credited to have been the first to discover clathrate hydrates in his lab.
In 1799 he experimented with nitrous oxide and was astonished at how it made him laugh, so he nicknamed it "laughing gas" and wrote about its potential anaesthetic properties in relieving pain during surgery.Davy was a baronet, President of the Royal Society (PRS), Member of the Royal Irish Academy (MRIA), Fellow of the Geological Society (FGS), and a member of the American Philosophical Society (elected 1810). Berzelius called Davy's 1806 Bakerian Lecture On Some Chemical Agencies of Electricity "one of the best memoirs which has ever enriched the theory of chemistry."

Bernd Heinrich Wilhelm von Kleist (18 October 1777 – 21 November 1811) was a German poet, dramatist, novelist, short story writer and journalist. His best known works are the theatre plays Das Käthchen von Heilbronn, The Broken Jug, Amphitryon and Penthesilea, and the novellas Michael Kohlhaas and The Marquise of O. Kleist died by suicide together with a close female friend who was terminally ill.
The Kleist Prize, a prestigious prize for German literature, is named after him, as was the Kleist Theater in his birthplace Frankfurt an der Oder.

Auguste-Maurice Barrès (French: [baʁɛs]; 19 August 1862 – 4 December 1923) was a French novelist, journalist, philosopher, and politician.

In politics, he was first elected to the Chamber of Deputies in 1889 as a Boulangist and would play a prominent political role for the rest of his life.

Guido da Verona (the pseudonym of Guido Verona; 7 May 1881 – 5 April 1939) was an Italian poet and novelist.

He later was the most commercially successful Italian writer between 1914 and 1939: particularly his novel Mimì Bluette, fiore del mio giardino, which reached 300,000 copies in 1922, an impressive run in Italy where illiteracy characterized the majority of the population.He was a signatory to the Manifesto of Fascist intellectuals in 1925; in 1929 he published a parody novel of Alessandro Manzoni's The Betrothed, that actually was an implicit satire against fascism.He became an intellectual unpopular with the Fascist regime and marginalized after the approval of racial laws. Da Verona committed suicide in Milan at age 57.
