Nationality is often an interesting question. To quote the German wikipedia page on the nobel prize [1] (translated by deepl):
> One of the consequences of this practice is that nationality information is sometimes controversial or confusing. For example, Elizabeth Blackburn, who is also an Australian citizen but is listed in the Nobellists only as an American with an Australian birthplace. In the case of prizewinners who stood between several nations, such as the Alsatian-born Albert Schweitzer, for example, the indication of only one nationality is also perceived as insufficient or, depending on the point of view of the observer, wrong. Another reason for discrepancies are the numerous state changes in the 19th and 20th centuries. Some prizewinners, for example, mention the place of birth with the nationality of the time and today, while others mention only one of the two. An example of this is Günter Blobel, whose birthplace lies in Poland today but is listed as a place in Germany. Mother Teresa was born in Skopje, which then belonged to the Ottoman Empire and is now the capital of Northern Macedonia. However, her family was Albanian, which is why she is often seen as an Albanian. However, none of the three states is mentioned in the official list of notices, but the place of birth is shown as belonging to Turkey, presumably because this was already a common name for the Ottoman Empire before the foundation of the Turkish state. Her nationality is declared Indian because she was an Indian citizen at the time of the award.
> Since the Nobel Peace Prize has already been awarded several times to laureates who have worked towards a solution to a conflict over the nationality of a region, the indication of nationality already runs the risk of being regarded as tendentious. For example, when the 14th Dalai Lama Tendzin Gyatsho was awarded the nationality Tibet was declared, although this state only exists in the form of an exile government. In 1998 and 1976, the state received awards for its efforts to settle the conflict in Northern Ireland. Here the Nobel Institute chose Northern Ireland as its nationality, although this region was never an independent state and no party to the conflict sought to establish one. The Nobelstiftung, on the other hand, names the United Kingdom as its nationality after its current formal affiliation.
