Wilhelm Conrad Röntgen (; German pronunciation: [ˈvɪlhɛlm ˈʁœntɡən] ; 27 March 1845 – 10 February 1923) was a German mechanical engineer and physicist, who, on 8 November 1895, produced and detected electromagnetic radiation in a wavelength range known as X-rays or Röntgen rays, an achievement that earned him the inaugural Nobel Prize in Physics in 1901. In honour of Röntgen's accomplishments, in 2004 the International Union of Pure and Applied Chemistry (IUPAC) named element 111, roentgenium, a radioactive element with multiple unstable isotopes, after him. The unit of measurement roentgen was also named after him.

George Frederic Watts (23 February 1817 – 1 July 1904) was a British painter and sculptor associated with the Symbolist movement. He said "I paint ideas, not things." Watts became famous in his lifetime for his allegorical works, such as Hope and Love and Life. These paintings were intended to form part of an epic symbolic cycle called the "House of Life", in which the emotions and aspirations of life would all be represented in a universal symbolic language.

Sir Isaac Pitman (4 January 1813 – 22 January 1897) was a teacher of the English language who developed the most widely used system of shorthand, known now as Pitman shorthand. He first proposed this in Stenographic Soundhand in 1837. He was also the vice-president of the Vegetarian Society. Pitman was knighted by Queen Victoria in 1894.

Oscar II (Oscar Fredrik; 21 January 1829 – 8 December 1907) was King of Sweden from 1872 until his death in 1907 and King of Norway from 1872 to 1905.
Oscar was the son of King Oscar I and Queen Josephine. He inherited the Swedish and Norwegian thrones when his brother died in 1872. Oscar II ruled during a time when both countries were undergoing a period of industrialization and rapid technological progress. His reign also saw the gradual decline of the Union of Sweden and Norway, which culminated in its dissolution in 1905. In 1905, the throne of Norway was transferred to his grandnephew Prince Carl of Denmark under the regnal name Haakon VII. When Oscar died in 1907, he was succeeded in Sweden by his eldest son, Gustaf V.
Oscar II is the paternal great-great-grandfather of King Carl XVI Gustaf of Sweden. King Frederik X of Denmark is Oscar II's descendant through his son Gustaf V. King Harald V of Norway; King Philippe of the Belgians; and Henri, Grand Duke of Luxembourg are also descendants of Oscar II, all through his third son Prince Carl, Duke of Västergötland.

Gustavus Adolphus (9 December [N.S 19 December] 1594 – 6 November [N.S 16 November] 1632), also known in English as Gustav II Adolf or Gustav II Adolph, was King of Sweden from 1611 to 1632, and is credited with the rise of Sweden as a great European power (Swedish: Stormaktstiden). During his reign, Sweden became one of the primary military forces in Europe during the Thirty Years' War, helping to determine the political and religious balance of power in Europe. He was formally and posthumously given the name Gustavus Adolphus the Great (Swedish: Gustav Adolf den store; Latin: Gustavus Adolphus Magnus) by the Riksdag of the Estates in 1634.He is often regarded as one of the greatest military commanders in modern history, with use of an early form of combined arms. His most notable military victory was the Battle of Breitenfeld in 1631. With his resources, logistics, and support, Gustavus Adolphus was positioned to become a major European leader, but he was killed a year later at the Battle of Lützen. He was assisted in his efforts by Count Axel Oxenstierna, the Lord High Chancellor of Sweden, who also acted as regent after his death.
Coming to the throne at the age of 16, Gustavus Adolphus inherited three wars from his father Charles IX of Sweden: border conflicts with Russia and Denmark–Norway, and a dynastic struggle with his first cousin, King Sigismund III Vasa of Poland. Of these, the Danish war was the most serious. During his reign, Sweden rose from the status of a Baltic Sea basin regional power to one of the great powers of Europe and a model of early modern era government. Gustavus Adolphus is known as the "father of modern warfare", or the first modern general. He taught a number of other military commanders, such as Lennart Torstensson, who would go on to expand the boundaries and power of the Swedish Empire after Gustavus Adolphus's death. Spoils meant he became a successful bookraider in Europe, targeting Jesuit collections.His contributions to Sweden's rise in power included reformation of the administrative structure. For example, he began Parish Registration of the population, so that the central government could more efficiently tax and conscript the people. He is also widely commemorated by Protestants in Europe as the main defender of their cause during the Thirty Years' War, with multiple churches, foundations and other undertakings named after him, including the Gustav-Adolf-Werk.

Frederick II (German: Friedrich II.; 24 January 1712 – 17 August 1786) was the monarch of Prussia from 1740 until 1786. He was the last Hohenzollern monarch titled King in Prussia, declaring himself King of Prussia after annexing Royal Prussia from the Polish–Lithuanian Commonwealth in 1772. His most significant accomplishments include his military successes in the Silesian wars, his reorganisation of the Prussian Army, the First Partition of Poland, and his patronage of the arts and the Enlightenment. Prussia greatly increased its territories and became a major military power in Europe under his rule. He became known as Frederick the Great (German: Friedrich der Große) and was nicknamed "Old Fritz" (German: der Alte Fritz).
In his youth, Frederick was more interested in music and philosophy than in the art of war, which led to clashes with his authoritarian father, Frederick William I of Prussia. However, upon ascending to the Prussian throne, he attacked and annexed the rich Austrian province of Silesia in 1742, winning military acclaim for himself and Prussia. He became an influential military theorist, whose analyses emerged from his extensive personal battlefield experience and covered issues of strategy, tactics, mobility and logistics.
Frederick was a supporter of enlightened absolutism, stating that the ruler should be the first servant of the state. He modernised the Prussian bureaucracy and civil service, and pursued religious policies throughout his realm that ranged from tolerance to segregation. He reformed the judicial system and made it possible for men of lower status to become judges and senior bureaucrats. Frederick also encouraged immigrants of various nationalities and faiths to come to Prussia, although he enacted oppressive measures against Catholics in Silesia and Polish Prussia. He supported the arts and philosophers he favoured, and allowed freedom of the press and literature. Frederick was almost certainly homosexual, and his sexuality has been the subject of much study. Because he died childless, he was succeeded by his nephew, Frederick William II. He is buried at his favourite residence, Sanssouci in Potsdam.
Nearly all 19th-century German historians made Frederick into a romantic model of a glorified warrior, praising his leadership, administrative efficiency, devotion to duty and success in building Prussia into a great power in Europe. Frederick remained an admired historical figure through Germany's defeat in World War I, and the Nazis glorified him as a great German leader prefiguring Adolf Hitler, who personally idolised him. His reputation became less favourable in Germany after World War II, partly due to his status as a Nazi symbol. Historians in the 21st century tend to view Frederick as an outstanding military leader and capable monarch, whose commitment to enlightenment culture and administrative reform built the foundation that allowed the Kingdom of Prussia to contest the Austrian Habsburgs for leadership among the German states.

Antoine Henri Becquerel (; French pronunciation: [ɑ̃twan ɑ̃ʁi bɛkʁɛl]; 15 December 1852 – 25 August 1908) was a French engineer, physicist, Nobel laureate, and the first person to discover radioactivity. For work in this field he, along with Marie Skłodowska-Curie and Pierre Curie, received the 1903 Nobel Prize in Physics. The SI unit for radioactivity, the becquerel (Bq), is named after him.

Louisa May Alcott (; November 29, 1832 – March 6, 1888) was an American novelist, short story writer, and poet best known for writing the novel Little Women (1868) and its sequels Little Men (1871) and Jo's Boys (1886). Raised in New England by her transcendentalist parents, Abigail May and Amos Bronson Alcott, she grew up among many well-known intellectuals of the day, including Margaret Fuller, Ralph Waldo Emerson, Nathaniel Hawthorne, Henry David Thoreau, and Henry Wadsworth Longfellow.Alcott's family suffered from financial difficulties, and while she worked to help support the family from an early age, she also sought an outlet in writing. She began to receive critical success for her writing in the 1860s. Early in her career, she sometimes used pen names such as A. M. Barnard, under which she wrote lurid short stories and sensation novels for adults that focused on passion and revenge.Published in 1868, Little Women is set in the Alcott family home, Orchard House, in Concord, Massachusetts, and is loosely based on Alcott's childhood experiences with her three sisters, Abigail May Alcott Nieriker, Elizabeth Sewall Alcott, and Anna Alcott Pratt. The novel was well-received at the time and is still popular today among both children and adults. It has been adapted for stage plays, films, and television many times.
Alcott was an abolitionist and a feminist and remained unmarried throughout her life. She also spent her life active in reform movements such as temperance and women's suffrage. She died from a stroke in Boston on March 6, 1888, just two days after her father's death.

Pierre Jules Théophile Gautier (US: goh-TYAY, French: [pjɛʁ ʒyl teɔfil ɡotje]; 30 August 1811 – 23 October 1872) was a French poet, dramatist, novelist, journalist, and art and literary critic.
While an ardent defender of Romanticism, Gautier's work is difficult to classify and remains a point of reference for many subsequent literary traditions such as Parnassianism, Symbolism, Decadence and Modernism. He was widely esteemed by writers as disparate as Balzac, Baudelaire, the Goncourt brothers, Flaubert, Pound, Eliot, James, Proust and Wilde.

Albrecht Dürer (; German: [ˈʔalbʁɛçt ˈdyːʁɐ]; 21 May 1471 – 6 April 1528), sometimes spelled in English as Durer, was a German painter, printmaker, and theorist of the German Renaissance. Born in Nuremberg, Dürer established his reputation and influence across Europe in his twenties due to his high-quality woodcut prints. He was in contact with the major Italian artists of his time, including Raphael, Giovanni Bellini, and Leonardo da Vinci, and from 1512 was patronized by Emperor Maximilian I.

Dürer's vast body of work includes engravings, his preferred technique in his later prints, altarpieces, portraits and self-portraits, watercolours and books. The woodcuts series are more Gothic than the rest of his work. His well-known engravings include the three Meisterstiche (master prints) Knight, Death and the Devil (1513), Saint Jerome in his Study (1514), and Melencolia I (1514). His watercolours mark him as one of the first European landscape artists, while his woodcuts revolutionised the potential of that medium.
Dürer's introduction of classical motifs into Northern art, through his knowledge of Italian artists and German humanists, has secured his reputation as one of the most important figures of the Northern Renaissance. This is reinforced by his theoretical treatises, which involve principles of mathematics, perspective, and ideal proportions.
