Göttingen Minipig (also known as the Göttinger or Goettingen Minipig) is a breed of miniature swine developed specifically for use in biomedical research.
 The Göttingen Minipig is a member of the species Sus scrofa domestica along with other domesticated swine.
 The Göttingen Minipig is best known for its exceptionally small size and its very clean and well-characterized health status.
 Development of this breed began in the late 1960s at the Institute of Animal Breeding and Genetics (Institut fϋr Tierzucht und Haustiergenetik) at the University of Göttingen, Germany, by crossbreeding the Minnesota minipig, the Vietnamese Potbelly Pig and the German Landrace pig.
 Today the Göttingen Minipig is bred at four separate locations globally and is used in life-saving biomedical research all over the world.
Carl J. Wiggers (May 28, 1883 – April 28, 1963), famous for his heart and blood-pressure research, was born in Davenport, Iowa to George and Margret Kuendal Wiggers, graduated from the University of Michigan with a M.D. in 1906, and attended the Institute of Physiology at the University of Munich.
 He was an instructor of physiology at the University of Michigan (1906–11), and assistant professor at Cornell University Medical School (1911–18).
 From 1918-53, he was professor and chairman of the Dept. of Physiology at Western Reserve University Medical School that became known as Case Western Reserve University School of Medicine.
 Wiggers achieved world recognition for developing a new method of registering heart and blood pressure, finding the effects of low oxygen pressure on circulation, discovering the effects of valve defects on the heart, studying the effects of shock, and his pioneering efforts along with Dr. Claude Beck and others in techniques of resuscitation from death in the operating room.
 He is perhaps most famous for his authoring of the Wiggers diagram, a diagram commonly used in teaching of cardiovascular research.
 After retiring as professor emeritus in 1953, Wiggers joined the Frank Bunts Institute of the Cleveland Clinic Foundation, taking part in postgraduate training for student doctors and in medical and scientific seminars.
 Wiggers established and was the first editor of the medical journal Circulation Research and authored 7 books and over 300 articles.
 In 1952 he received the Gold Heart Award from the American Heart Association.
 In 1951 he was elected to the National Academy of Sciences.
 In 1954 he received the Modern Medicine Award, and in 1955 the Albert Lasker Award for distinguished research in cardiovascular research.
Jane Shelby Richardson (born January 25, 1941) is an American biophysicist who developed the Richardson diagram, or ribbon diagram, method of representing the 3D structure of proteins.
 She is a professor in biochemistry at Duke University.
Ernst Heinrich Friedrich Meyer (1 January 1791 Hanover, Brunswick-Lüneburg – 7 August 1858 Königsberg, East Prussia) was a German botanist and botanical historian.
 Born in Hanover, he lectured in Göttingen and in 1826 became a professor of botany at the University of Königsberg, as well as Director of the Botanical Garden.
 His botanical specialty was the Juncaceae, or family of rushes.
 His major work was the four-volume "Geschichte der Botanik" (“History of Botany,” 1854–57).
 His history covered ancient authorities such as Aristotle and Theophrastus, explored the beginnings of modern botany in the context of 15th- and 16th-century intellectual practice, and offered a wealth of biographical data on early modern botanists.
 Julius von Sachs pronounced him “no great botanist” but admitted that he “possessed a clever and cultivated intellect.”
Johann Jakob Quandt (Lithuanian: "Jonas Jokūbas Kvantas" ; 27 March 1686 in Königsberg – 17 January 1772 in Königsberg) was a German orthodox Lutheran theologian, professor of theology in Königsberg.
 He opposed Pietism, but sympathized with Wolffianism.
 He is known for sponsoring the first complete translation of the Bible into Lithuanian, the Quandt Bible of 1735.
 He was also a librarian of the Königsberg Public Library (first librarian, 1714–18).
Kaoru Ishikawa (石川 馨 , Ishikawa Kaoru , July 13, 1915 – April 16, 1989) was a Japanese organizational theorist, Professor at the Faculty of Engineering at The University of Tokyo, noted for his quality management innovations.
 He is considered a key figure in the development of quality initiatives in Japan, particularly the quality circle.
 He is best known outside Japan for the Ishikawa or cause and effect diagram (also known as fishbone diagram) often used in the analysis of industrial processes.
Willy Schwarz (born 8 December 1906 in Göttingen, died 1982) was a German physician and anatomist, who was Professor and held the second chair in anatomy at the Free University of Berlin from 1966 to 1976.
 He obtained his Habilitation in 1937, and taught at the University of Jena and the University of Königsberg prior to 1945.
 From 1949, he was employed at the Free University of Berlin, as Adjunct Professor ("apl.
 Professor") 1949–1951, as Professor Extraordinarius ("ao.
 Professor") 1951–1966 and as Professor Ordinarius from 1966.
 He was Director of the Research Department for Electron Microscopy and of the Institute for Anatomy.
The Göttingen manuscript is the earliest known work devoted entirely to modern chess.
 It is a Latin text of 33 leaves held at the University of Göttingen.
 A quarto parchment manuscript of 33 leaves, ff.
 1–15a are a discussion of twelve chess openings, f. 16 is blank, and ff.
 17–31b are a selection of thirty chess problems, one on each page with a diagram and solution.
 Authorship and exact date of the manuscript are unknown.
 Similarities to Lucena's "Repeticion de Amores e Arte de Axedres con CL iuegos de partido" (c. 1497) have led some scholars to surmise that it was written by Lucena or that it was one of Lucena's sources.
 Although the manuscript is generally assumed to be older than Lucena's work, this is not established.
 The manuscript has been ascribed possible writing dates of 1500–1505 or 1471.
Hermann Minkowski ( ; ] ; 22 June 1864 – 12 January 1909) was a mathematician and professor at Königsberg, Zürich and Göttingen.
 He created and developed the geometry of numbers and used geometrical methods to solve problems in number theory, mathematical physics, and the theory of relativity.
The Minkowski diagram, also known as a spacetime diagram, was developed in 1908 by Hermann Minkowski and provides an illustration of the properties of space and time in the special theory of relativity.
 It allows a qualitative understanding of the corresponding phenomena like time dilation and length contraction without mathematical equations.
