Maurits Cornelis Escher (Dutch pronunciation: [ˈmʌurɪt͡s kɔrˈneːlɪs ˈɛʃər]; 17 June 1898 – 27 March 1972) was a Dutch graphic artist who made woodcuts, lithographs, and mezzotints, many of which were inspired by mathematics.
Despite wide popular interest, for most of his life Escher was neglected in the art world, even in his native Netherlands. He was 70 before a retrospective exhibition was held. In the late twentieth century, he became more widely appreciated, and in the twenty-first century he has been celebrated in exhibitions around the world.
His work features mathematical objects and operations including impossible objects, explorations of infinity, reflection, symmetry, perspective, truncated and stellated polyhedra, hyperbolic geometry, and tessellations. Although Escher believed he had no mathematical ability, he interacted with the mathematicians George Pólya, Roger Penrose, and Donald Coxeter, and the crystallographer Friedrich Haag, and conducted his own research into tessellation.
Early in his career, he drew inspiration from nature, making studies of insects, landscapes, and plants such as lichens, all of which he used as details in his artworks. He traveled in Italy and Spain, sketching buildings, townscapes, architecture and the tilings of the Alhambra and the Mezquita of Cordoba, and became steadily more interested in their mathematical structure.
Escher's art became well known among scientists and mathematicians, and in popular culture, especially after it was featured by Martin Gardner in his April 1966 Mathematical Games column in Scientific American. Apart from being used in a variety of technical papers, his work has appeared on the covers of many books and albums. He was one of the major inspirations for Douglas Hofstadter's Pulitzer Prize-winning 1979 book Gödel, Escher, Bach.

Max Theodor Felix von Laue (German: [maks fɔn ˈlaʊ̯ə] ; 9 October 1879 – 24 April 1960) was a German physicist who received the Nobel Prize in Physics in 1914 for his discovery of the diffraction of X-rays by crystals.In addition to his scientific endeavors with contributions in optics, crystallography, quantum theory, superconductivity, and the theory of relativity, Laue had a number of administrative positions which advanced and guided German scientific research and development during four decades. A strong objector to Nazism, he was instrumental in re-establishing and organizing German science after World War II.

Andrew M. Greeley (February 5, 1928 – May 29, 2013) was an American Catholic priest, sociologist, journalist and popular novelist. He was a professor of sociology at the University of Arizona and the University of Chicago, and a research associate with the National Opinion Research Center (NORC).
For many years, Greeley wrote a weekly column for the Chicago Sun-Times and contributed regularly to The New York Times, the National Catholic Reporter, America, and Commonweal.

Gerrit Achterberg (20 May 1905 – 17 January 1962) was a Dutch poet. His early poetry concerned a desire to be united with a beloved in death.
Achterberg was born in Nederlangbroek in the Netherlands as the third son of a family of eight children. He was raised as a Protestant within the Calvinist tradition. His father was a coachman until the automobile gained popularity. Achterberg was a very good student, and in 1924 he embarked on a career as a teacher. In the same year, he made his literary debut together with Arie Dekkers, who had encouraged him to write, together publishing De Zangen van Twee Twintigers (English: The Songs of Two Twenty-Somethings).
Meanwhile, Achterberg became more withdrawn and introverted. After he was turned down by the military due to "sickness of the soul", he threatened to kill himself.
Achterberg's literary career began to take off when Roel Houwink presented himself as his mentor. Achterberg published his collection "Afvaart" in 1931, in which his famous theme, of a love irrevocably lost, was already strongly present. After the publication of "Afvaart", Achterberg suffered a mental breakdown and was committed to a psychiatric institution several times. His mental instability caused occasional violent outbursts.
These eruptions of violence escalated in 1937. At that time, Achterberg was living in Utrecht and was again engaged to be married. On 15 December 1937 he tried to force himself on Bep van Es, the 16-year-old daughter of his landlady. When the latter tried to stop him, he shot and killed her, and wounded her daughter. After the shooting, he turned himself in and was sentenced to involuntary commitment. He was committed until 1943. During this commitment and the period following (between 1939 and 1953), he published 22 collections of poetry.
In 1946 he married his childhood friend Cathrien van Baak, with whom he lived in Leusden until he died from a heart attack in 1962.In 1959, Achterberg received the Constantijn Huygens Prize for his entire body of work.
Achterberg's most famous work is the Ballad Reiziger doet Golgotha (A Tourist Does Golgotha) and the sonnet sequence Ballade van de gasfitter (1953;Ballad of the gasfitter). J.M. Coetzee included this sonnet sequence in an anthology of his English translations of Dutch poetry entitled Landscape with Rowers (2004). Earlier in his career, Coetzee also wrote an essay on this sonnet sequence, titled: 'Achterberg's "Ballade van de gasfitter": The Mystery of I and You' (1977),

Wilhelm Bauer (23 December 1822 – 20 June 1875) was a German inventor and engineer who built several hand-powered submarines.

Friedrich Hermann Hund (4 February 1896 – 31 March 1997) was a German physicist from Karlsruhe known for his work on atoms and molecules.

Ferdinand Ritter von Mannlicher (January 30, 1848 – January 20, 1904) was an Austrian engineer and small arms designer. Along with James Paris Lee, Mannlicher was particularly noted for inventing the en-bloc clip charger-loading box magazine system. Later, while making improvements to other inventors' prototype designs for rotary-feed magazines, Mannlicher, together with his protégé Otto Schönauer, patented a perfected rotary magazine design, the Mannlicher–Schönauer rifle, which was a commercial and military success.
