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.

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.

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.

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.
