Since 1901, the Nobel Prize in Literature (Swedish: "Nobelpriset i litteratur" ) has been awarded annually to an author from any country who has, in the words of the will of Alfred Nobel, produced "in the field of literature the most outstanding work in an ideal direction" (original Swedish: "den som inom litteraturen har producerat det mest framstående verket i en idealisk riktning").
 Though individual works are sometimes cited as being particularly noteworthy, here "work" refers to an author's work as a whole.
 The Swedish Academy decides who, if anyone, will receive the prize in any given year.
 The academy announces the name of the chosen laureate in early October.
 It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895; the others are the Nobel Prize in Chemistry, Nobel Prize in Physics, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine.
Zhores Ivanovich Alferov (Russian: Жоре́с Ива́нович Алфёров , ] ; Belarusian: Жарэс Іва́навіч Алфёраў ; born 15 March 1930) is a Soviet and Russian physicist and academic who contributed significantly to the creation of modern heterostructure physics and electronics.
 He is the inventor of the heterotransistor and the winner of 2000 Nobel Prize in Physics.
 He is also a Russian politician and has been a member of the lower house of the Russian parliament the State Duma, since 1995.
Guglielmo Marconi, 1st Marquis of Marconi ( ; ] ; 25 April 187420 July 1937) was an Italian inventor and electrical engineer known for his pioneering work on long-distance radio transmission and for his development of Marconi's law and a radio telegraph system.
 He is usually credited as the inventor of radio, and he shared the 1909 Nobel Prize in Physics with Karl Ferdinand Braun "in recognition of their contributions to the development of wireless telegraphy".
Since 1949, there have been twenty-five Japanese winners of the Nobel Prize (Swedish: "Nobelpriset" ).
 The Nobel Prize is a Sweden-based international monetary prize.
 The award was established by the 1895 will and estate of Swedish chemist and inventor Alfred Nobel.
 It was first awarded in Physics, Chemistry, Physiology or Medicine, Literature, and Peace in 1901.
 An associated prize, The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, was instituted by Sweden's central bank in 1968 and first awarded in 1969.
Karl Ferdinand Braun (6 June 1850 – 20 April 1918) was a German inventor, physicist and Nobel laureate in physics.
 Braun contributed significantly to the development of radio and television technology: he shared with Guglielmo Marconi the 1909 Nobel Prize in Physics.
The Nobel Prize in Physics (Swedish: "Nobelpriset i fysik" ) is a yearly award given by the Royal Swedish Academy of Sciences for those who conferred the most outstanding contributions for mankind in the field of physics.
 It is one of the five Nobel Prizes established by the will of Alfred Nobel in 1895 and awarded since 1901; the others being the Nobel Prize in Chemistry, Nobel Prize in Literature, Nobel Peace Prize, and Nobel Prize in Physiology or Medicine.
Aage Niels Bohr (] ; 19 June 1922 – 8 September 2009) was a Danish nuclear physicist who shared the Nobel Prize in Physics in 1975 with Ben Mottelson and James Rainwater "for the discovery of the connection between collective motion and particle motion in atomic nuclei and the development of the theory of the structure of the atomic nucleus based on this connection".
 Starting from Rainwater's concept of an irregular-shaped liquid drop model of the nucleus, Bohr and Mottelson developed a detailed theory that was in close agreement with experiments.
 Since his father, Niels Bohr, had won the prize in 1922, he and his father were one of the six pairs of fathers and sons who have both won the Nobel Prize and one of the four pairs who have both won the Nobel Prize in Physics.
The Nobel Prize in Physiology or Medicine (Swedish: "Nobelpriset i fysiologi eller medicin" ), administered by the Nobel Foundation, is awarded once a year for outstanding discoveries in the fields of life sciences and medicine.
 It is one of five Nobel Prizes established in 1895 by Swedish chemist Alfred Nobel, the inventor of dynamite, in his will.
 Nobel was personally interested in experimental physiology and wanted to establish a prize for progress through scientific discoveries in laboratories.
 The Nobel Prize is presented to the recipient(s) at an annual ceremony on 10 December, the anniversary of Nobel's death, along with a diploma and a certificate for the monetary award.
 The front side of the medal provides the same profile of Alfred Nobel as depicted on the medals for Physics, Chemistry, and Literature; its reverse side is unique to this medal.
This is a list of Danish Nobel laureates.
 Since the Nobel Prize was established per the will of Swedish inventor Alfred Nobel in 1895, 12 of the prize winners have been from Denmark.
 The first Danish Nobel laureate was Niels Ryberg Finsen, who won a Nobel Prize for medicine in 1903 for his work in using light therapy to treat diseases.
 The most recent Danish Nobel Prize winner was Jens Skou who won the prize in chemistry for his discovery over the enzyme, Na+/K+-ATPase in 1997.
 To date, of the 13 Nobel Prizes won by Danish people, 5 have been for medicine, 3 have been for physics, 3 have been for literature, 1 has been for chemistry and one has been for peace.
Since 1957, there have been eight Chinese (including Chinese born) winners of the Nobel Prize (Swedish: "Nobelpriset" ).
