Jozef Karol Hell (Slovak: "Jozef Karol Hell", German: "Josef/ph Karl Hell", Hungarian: "Hell József Károly") (15 May 1713, Szélakna (Windschacht, Piarg, now Štiavnické Bane) - 11 March 1789, Selmecbánya (Schemnitz, now Banská Štiavnica)) was a Hungarian mining engineer and inventor, who invented the water-pillar (water pump machine) in 1749 (first use 1753).
 It is mainly used today for oil extraction.
 He also proposed construction of the tajchy reservoirs around Selmecbánya (Schemnitz, Banská Štiavnica).
 He was a student of Sámuel Mikoviny in 1737.
 Regardless of his nationality, he is a pride of both Hungarian and Slovak nations.
José Arturo Castellanos Contreras (San Vicente, El Salvador, December 23, 1893 — San Salvador, June 18, 1977) was a Salvadoran army colonel and diplomat who, while working as El Salvador's Consul General for Geneva during World War II, and in conjunction with a Jewish-Hungarian businessman named György Mandl, helped save up to 40,000 Jews and Central Europeans from Nazi persecution by providing them with Political Asylum (Salvadoran nationality).
Australian nationality law determines who is and who is not an Australian citizen.
 The status of Australian nationality or Australian citizenship was created by the "Nationality and Citizenship Act 1948", (in 1973 renamed the "Australian Citizenship Act 1948") which came into force on 26 January 1949.
 The 1948 Act was amended many times, notably in 1973, 1984, 1986 and 2002.
 The "Australian Citizenship Act 2007" replaced the 1948 Act, commencing on 1 July 2007.
Earl Silas Tupper (July 28, 1907 – October 5, 1983) was an American-born businessman and inventor, best known as the inventor of Tupperware, an airtight plastic container for storing food.
Tupperware is the name of a home products line that includes preparation, storage, containment, and serving products for the kitchen and home.
 It also includes plastic containers used to store goods and/or food.
 In 1942, Earl Tupper developed his first bell shaped container; the brand products were introduced to the public in 1948.
Abdullah Ghubn, born in Libya on 31 July 1979 but of Jordanian nationality, is a businessman who currently holds the position of General Manager of the NAS Group (Nasir Bin Abdullah and Sons Group), that is chaired by Qatari Sheikh Abdullah Bin Nasser Al Thani, whose business Ghubn represents.
 On 28 July 2010, two days after acquiring the shares of Málaga CF by the NAS Group, Sheikh Abdullah Ben Nasser Al Thani’s right hand man, Abdullah Ghubn, joined the Spanish football club’s Board of Directors taking on the functions of Vice president and CEO of the Club.
Frederick Gilbert "Commodore" Bourne (December 20, 1851 – March 1919) was an American businessman.
 He served as the 5th President of the Singer Manufacturing Company between 1889 and 1905.
 He made the business "perhaps the first modern multinational industrial enterprise of any nationality".
Sidney (or Sydney) Stanley ("né" Solomon Wulkan, alias Solomon Koszyski, alias Stanley Rechtand, later Schlomo ben Chaim) (1899/1905 – 1969) was a Polish "émigré" to the UK who became a dubious businessman of precarious ethics before claiming to be a "contact man", able to influence politicians and civil servants in return for cash bribes, claims that led to a great scandal and investigation by the Lynskey tribunal of 1948.
 There is also evidence that Stanley spied against the UK for the armed nationalist activist Irgun organisation.
 Stanley was ordered deported, but had lost his Polish nationality, and as a result was a stateless person.
 Stanley was then placed under heavy restrictions and police surveillance.
 In 1949, he evaded police and fled to France and thence to Israel, where he was granted citizenship through right-of-return.
 There he lived out the remainder of his life in relative obscurity.
New Zealand nationality law (Raraunga Aotearoa in Māori) determines who is and who is not a New Zealand citizen.
 The status of New Zealand citizenship was created on 1 January 1949 by the "British Nationality and New Zealand Citizenship Act 1948".
 Prior to this date, New Zealanders were only British subjects and New Zealand had the same nationality legislation as the United Kingdom and other Commonwealth countries (see also British nationality law).
The Polar Music Prize is a Swedish international award founded in 1989 by Stig Anderson, best known as the manager of the Swedish band ABBA, with a donation to the Royal Swedish Academy of Music.
 The award is annually given to one contemporary musician and one classical musician.
 Exceptions were made in 2001, when it was awarded to three musicians (one composer, one contemporary musician and one inventor), and 2003, when it was awarded only to one musician.
 Without any restrictions of nationality, the prize is to be "awarded for significant achievements in music and/or musical activity, or for achievements which are found to be of great potential importance for music or musical activity, and it shall be referable to all fields within or closely connected with music".
 The prize has been called the "Nobel Prize of Music" in Sweden.
