People from the Province of Hanover

Sir Hans Adolf Krebs, FRS (, German: [hans ˈʔaːdɔlf ˈkʁeːps] ; 25 August 1900 – 22 November 1981) was a German-British biologist, physician and biochemist. He was a pioneer scientist in the study of cellular respiration, a biochemical process in living cells that extracts energy from food and oxygen and makes it available to drive the processes of life. He is best known for his discoveries of two important sequences of chemical reactions that take place in the cells of nearly all organisms, including humans, other than anaerobic microorganisms, namely the citric acid cycle and the urea cycle. The former, often eponymously known as the "Krebs cycle", is the sequence of metabolic reactions that allows cells of oxygen-respiring organisms to obtain far more ATP from the food they consume than anaerobic processes such as glycolysis can supply; and its discovery earned Krebs a Nobel Prize in Physiology or Medicine in 1953. With Hans Kornberg, he also discovered the glyoxylate cycle, a slight variation of the citric acid cycle found in plants, bacteria, protists, and fungi.
Krebs died in 1981 in Oxford, where he had spent 13 years of his career from 1954 until his retirement in 1967 at the University of Oxford.

Julius Guttmann (Hebrew: יוליוס גוטמן), born Yitzchak Guttmann (15 April 1880 in Hildesheim – 19 May 1950 in Jerusalem), was a German-born rabbi, Jewish theologian, and philosopher of religion.

Wolfram Sievers (10 July 1905 – 2 June 1948) was a Nazi and convicted war criminal for medical atrocities carried out while he was managing director (Reichsgeschäftsführer) of the Ahnenerbe from 1935–1945. He was convicted of war crimes in the Doctors' Trial in 1947 and executed by hanging in 1948.

Wilhelm Kolle (born 2 November 1868 in Lerbach near Osterode am Harz, died 10 May 1935) was a German bacteriologist and hygienist. He served as the second director of the Royal Institute for Experimental Therapy, succeeding its founder, the Nobel laureate Paul Ehrlich. He was also the original author, with Heinrich Hetsch, of the famous book Experimental Bacteriology, one of the most authoritative works in microbiology in the first half of the 20th century.
Following studies of medicine at the universities of Göttingen, Halle and Würzburg, he became an assistant to Robert Koch at the Institut für Infektionskrankheiten (Institute for Infectious Diseases) in Berlin (1893–97). In 1897–98 he performed research of rinderpest and leprosy in South Africa, and in 1900, on behalf of the Egyptian government, studied rinderpest in Sudan.
In 1901 he became departmental head at the Institut für Infektionskrankheiten, followed by an appointment as professor of hygiene and bacteriology at the University of Bern (1906). As a military physician and hygienist during World War I, he was highly successful in vaccination against diphtheria and cholera. In 1917, he became director of the Royal Institute for Experimental Therapy and of the Georg Speyer House in Frankfurt am Main.
Kolle made numerous contributions in the fields of serology, microbiology and chemotherapy. He is credited with the development of an anti-meningococcus serum, as well as a vaccine against rinderpest. He introduced an improved Salvarsan preparation for treatment of syphilis, and in 1896 developed a heat-inactivated cholera vaccine that was used extensively during the 20th century.He was the father of the painter Helmut Kolle (1899–1931).

Otto Karl Robert Wernicke (30 September 1893, Osterode am Harz – 7 November 1965) was a German actor. He is best known for his role as police inspector Karl Lohmann in the two Fritz Lang films M and The Testament of Dr. Mabuse.
Married to a Jewish woman, he was only able to continue working in Germany after the Nazi Party took power in 1933 because he received a special dispensation from the Reich Chamber of Culture. In 1943, he portrayed Captain Smith in Titanic, the first film on the subject which was simply titled Titanic, and the first to combine various fictional characters and subplots with the true events of the sinking; both conventions went on to become a staple of Titanic films. After being cast in 1944 in the propaganda epic Kolberg, he was added to the Gottbegnadeten-Liste, a list of artists considered crucial to Nazi culture which Joseph Goebbels compiled for Adolf Hitler's approval.

Karl Bernhard Dall (German: [kaʁl ˈdal] , 1 February 1941 – 23 November 2020) was a German comedian, singer, and television presenter. His distinctive 'hanging' eye was caused by a congenital ptosis.

Henri Nannen (25 December 1913 in Emden – 13 October 1996 in Hanover) was a German journalist and art collector. He became one of the most prominent journalists and magazine publishers in Germany.
His father was a police officer in Emden who was removed from his post by the NSDAP. After a one-year book dealer apprenticeship he studied the history of art at the University of Munich. In the 1930s he started working as a journalist. During the war he served in SS-Standarte Kurt Eggers, a propaganda unit in Italy. Being large, well-built and fair haired, he corresponded to the racial ideals of the time in Germany. This made him the speaker of the Olympic Oath during the 1936 event in Berlin – for Riefenstahl's film, but not in reality. Many years after the war, he confessed that "I knew what was happening ... but I was too cowardly to do something against it." He got back to journalism while working for the Hannoverschen Neusten Nachrichten, the daily newspaper Abendpost and the youth newspaper Zickzack.
He was the founder of Gruner + Jahr publishing house and the news magazine Der Stern. He led the magazine from 1948 to 1980 to become one of the strongest in Europe. Gruner + Jahr is the largest publisher in Europe as of 2014.
Nannen gained popularity as an art collector and benefactor of the Kunsthalle in Emden, an art museum, that he built in 1983. The annual Henri Nannen Prizes are awarded in his honor by Gruner + Jahr. The Henri-Nannen-Schule (formerly Hamburger Journalistenschule), is the journalist school of Gruner + Jahr and is considered one of the best schools of journalism in Germany, along with the German School of Journalism (Deutsche Journalistenschule) in Munich.He was married to Eske Nannen (born 1942), a former actress. Henri Nannen has a son Christian Nannen (born 1946), co-owner of Hamburg suitcase-producer Travelite.
