Dr. Ulf Dietrich Merbold (born June 20, 1941) is the first West German citizen and second German native (after Sigmund Jähn) to have flown in space.
 He is also the first member of the European Space Agency Astronaut Corps to participate in a spaceflight mission and the first non-US citizen to reach orbit in a US spacecraft.
 In 1983, he and Byron Lichtenberg became the first Payload Specialists to fly on the shuttle.
The Promise (original title: "Das Versprechen") is a German documentary film directed by Marcus Vetter with Karin Steinberger.
 The film tells the crime story of the double murder of Derek and Nancy Haysom on 30 March 1985 in Lynchburg, Virginia.
 The film focuses on the two main protagonists Jens Söring, son of a German diplomat, and Elizabeth Haysom, the daughter of the murdered couple.
 Both were sentenced to life in prison.
 The film makes use of extensive original footage from press archives, as the two court cases were the first lawsuits to be broadcast nationwide on American television.
 In the film, these recordings from 1985 to 1990 are combined with scenes shot during the making of the film, including interviews with Jens Söring, witnesses, the investigators involved in the case, lawyers, prosecutors and journalists.
 In addition, extensive materials such as original crime scene photos and evidence, court transcripts, newspaper archives, love letters and diaries of the two main protagonists were evaluated in the film.
German nationality law is the law governing the acquisition, transmission and loss of German citizenship.
 The law is based on a mixture of the principles of "jus sanguinis" and "jus soli".
 In other words, one usually acquires German citizenship if a parent is a German citizen, irrespective of place of birth, or by birth in Germany to parents with foreign nationality if certain requirements are fulfilled.
 Naturalisation is also possible for foreign nationals after six to eight years of legal residence in Germany.
 However, non-EU and non-Swiss citizens must usually renounce their old citizenship before being naturalised in Germany.
 Citizens of other EU countries and of Switzerland usually can keep their old citizenship.
 Some EU countries do not allow dual citizenship even with other EU countries.
 German citizens wanting to acquire a non-EU or non-Swiss citizenship and to maintain their German citizenship must apply for a permission ("Beibehaltungsgenehmigung") before acquiring the other citizenship, or they will automatically lose their German citizenship when they acquire the foreign citizenship.
 For details, see section "Dual citizenship."
Jens Söring (born August 1, 1966 in Bangkok, Thailand) is a German citizen who in 1990 was convicted of two counts of first-degree murder in Virginia, United States.

Jagoda Marinić (born September 20, 1977 in Waiblingen) is a prize-winning author, novelist, playwright, essayist, and journalist from Germany.
 She has what is often called a “migrant background,” a term she rejects; her parents emigrated from Dalmatia in Croatia, SFR Yugoslavia to Germany in the 1970s.
 She herself was born in Germany, became a German citizen, and speaks and writes in prominent venues about identity, migration, citizenship, and integration.
 She lives in Heidelberg.
German passports are issued to nationals of Germany for the purpose of international travel.
 A German passport is, besides the German ID card and the German Emergency Travel Document (called ""), the only other officially recognised document that German authorities will routinely accept as proof of identity from German citizens.
 Besides serving as proof of identity and presumption of German nationality, they facilitate the process of securing assistance from German consular officials abroad (or other EU-members in the case that a German consular facility is absent).
 German passports are valid for ten years (for people older than 24) or six years (for people until the age of 24) and share the standardised layout and burgundy red design with other EU passports. Every German citizen is also a citizen of the European Union.
 The passport, along with the national identity card allows for free rights of movement and residence in any of the states of the European Union and European Economic Area.
Heidi Hazell (24 September 1962 – 7 September 1989) was an IRA murder victim.
 The investigation into the murder of the German citizen was reopened in March 2015.
 The German Federal Attorney may not regard the Good Friday Agreement as relevant in terms of favourable terms, i.e. reduced prison sentencing for Pira members etc.
 The murder of Heidi, a German citizen found place in Germany and the country is not bound to the Agreement between Great Britain and the Republic of Ireland.
A Germanophile, Teutonophile or Teutophile is a person who is fond of German culture, German people and Germany in general or who exhibits German nationalism in spite of not even being either an ethnic German or a German citizen.
 The love of the "German way", called "Germanophilia" or "Teutonophilia", is the opposite to Germanophobia.
Elizabeth Roxanne Haysom (born April 15, 1964) is a Canadian citizen who, along with her former boyfriend, Jens Söring, was convicted of orchestrating the double murder of her parents, Derek and Nancy Haysom, in 1985.
 Following the Haysoms' murders, Haysom and Söring were arrested in London, England, for check fraud and shoplifting.
 Haysom is currently serving a 90-year prison sentence at the Fluvanna Correctional Center for Women in Troy, Virginia, after pleading guilty to two counts of accessory to murder before the fact in 1987.
Christine Schürrer (born June 30, 1976 in Hanover) is a German citizen who was convicted of murdering two Swedish children, and seriously injuring their mother with 15 blows to the head with a hammer, after attacking them in their home in Arboga, Sweden, on March 17, 2008.
 The motive for the murders has been identified as jealousy, since Schürrer had dated the children's stepfather in 2006 while he was on holiday on the Greek island of Crete where she was working at a local hostel.
