Jean-Henri Casimir Fabre (21 December 1823 – 11 October 1915) was a French naturalist, entomologist, and author known for the lively style of his popular books on the lives of insects.

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.

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.

Oscar Pletsch (26 March 1830 – 12 January 1888) was a German illustrator.

Antoine Hercule Romuald Florence (February 29, 1804 – March 27, 1879) was a Monegasque-Brazilian painter and inventor, known as the isolate inventor of photography in Brazil, three years before Daguerre (but six years after Nicéphore Niépce), using the matrix negative/positive, still in use. According to Kossoy, who examined Florence's notes, he referred to his process, in French, as photographie in 1834, at least four years before John Herschel coined the English word photography.

Eduard von Martens (18 April 1831 – 14 August 1904) also known as Carl or Karl Eduard von Martens, was a German zoologist.Born in Stuttgart in 1831, von Martens attended university in Tübingen, where he graduated in 1855. He then moved to Berlin, where he would be based for the remainder of his career, both at the Zoological Museum of the Berlin University (from 1855) and, from 1859 on, at the Museum für Naturkunde.In 1860, he embarked on the Thetis expedition of the Prussian expedition to Eastern Asia. When the expedition returned to Europe in 1862, von Martens continued to travel around Maritime Southeast Asia for 15 months. He published the results of the "Thetis" expedition in two volumes, constituting the Zoologischer Theil of the "Preussische Expedition nach Ost-Asien." Vol. ii, consisting of 447 pages and 22 plates, contained a very full account of the land molluscs.
Back in Berlin, von Martens was curator of the malacological and other invertebrate sections until his death.Von Martens described 155 new genera (150 of them molluscs) and almost 1,800 species (including around 1,680 molluscs, 39 crustaceans, and 50 echinoderms).
He was a foreign member of the Linnean Society of London, and a corresponding member of the Zoological Society of London.

Carl Offterdinger (January 8, 1829 in Stuttgart – January 12, 1889 in Stuttgart) was a German figure and genre painter and illustrator.

Christian Gottlieb Ferdinand Ritter von Hochstetter (30 April 1829 – 18 July 1884) was a German-Austrian geologist.

Johann Heinrich Wilhelm Tischbein, known as the Goethe Tischbein (15 February 1751 in Haina – 26 June 1829 in Eutin), was a German painter from the Tischbein family of artists.

François-Vincent Raspail, L.L.D., M.D. (25 January 1794 – 7 January 1878) was a French chemist, naturalist, physician, physiologist, attorney, and socialist politician.
