The Royal Swedish Academy of Sciences was given the task to select the Laureates in Economic Sciences starting in 1969.</p> <p><a href="https://web.archive.org/web/20200526134452/https://www.nobelprize.org/the-nobel-prize-organisation/prize-awarding-institutions/">Links to the prize-awarding institutions’ websites</a></p> <p><strong>Could you give me the mailing address or email address of a Nobel Laureate?</strong></p> <p>The Nobel Foundation does not disclose addresses to Nobel Laureates out of courtesy. Please contact the institution or university to which the Nobel Laureate was affiliated at the time of the award.</p> <p><a id="par3" name="par3"></a></p> <h2>Nobel Prize</h2> <p><strong>Why isn’t there a Nobel Prize in</strong><strong> mathematics,</strong><strong> engineering, biology or environmental science?</strong></p> <p>The Nobel Prizes, as designated in the <a href="https://web.archive.org/web/20200526134452/https://www.nobelprize.org/alfred-nobel/full-text-of-alfred-nobels-will/">will of Alfred Nobel</a>, are in physics, chemistry, physiology or medicine, literature and peace. Only once during these years has a prize been added, “a Memorial Prize”: The Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, donated by Sweden’s central bank to celebrate its tercentenary in 1968. The Board of Directors later decided to keep the original five prizes intact and not to permit new additions.</p> <p><strong>How can I propose new invention for the Nobel Prize?</strong></p> <p>First you have to check that you are a qualified nominator. Here you can find information on the nomination process for each prize category:</p> <p><a href="https://web.archive.org/web/20200526134452/https://www.nobelprize.org/nomination/nomination-and-selection-of-physics-laureates/">Nomination and selection of Physics Laureates</a><br/> <a href="https://web.archive.org/web/20200526134452/https://www.nobelprize.org/nomination/nomination-and-selection-of-chemistry-laureates/">Nomination and selection of Chemistry Laureates</a><br/> <a href="https://web.archive.org/web/20200526134452/https://www.nobelprize.org/nomination/nomination-and-selection-of-medicine-laureates/">Nomination and selection of Medicine Laureates</a><br/> <a href="https://web.archive.org/web/20200526134452/https://www.nobelprize.org/nomination/nomination-and-selection-of-literature-laureates/">Nomination and selection of Literature Laureates</a><br/> <a href="https://web.archive.org/web/20200526134452/https://www.nobelprize.org/nomination/nomination-and-selection-of-peace-prize-laureates/">Nomination and selection of Peace Prize Laureates</a><br/> <a href="https://web.archive.org/web/20200526134452/https://www.nobelprize.org/nomination/nomination-and-selection-of-laureates-in-economic-sciences/">Nomination and selection of Laureates in Economic Sciences</a></p> <p><strong>Is it possible to revoke a Nobel Prize?</strong></p> <p>No. Neither <a href="https://web.archive.org/web/20200526134452/https://www.nobelprize.org/alfred_nobel/will/">Alfred Nobel’s will</a> nor the <a href="https://web.archive.org/web/20200526134452/https://www.nobelprize.org/about/statutes-of-the-nobel-foundation/">Statutes of the Nobel Foundation</a> mention any such possibility. None of the prize awarding committees in Stockholm and Oslo has ever considered to revoke a prize once awarded.</p> <p><strong>Do the Nobel Committees ever reconsider a choice?</strong></p> <p>No. For the very same reasons referred to above. According to the Statutes of the Nobel Foundation, § 10, “No appeals may be made against the decision of a prize-awarding body with regard to the award of a prize”.</p> <p><strong>How do I propose a new Nobel Prize?</strong></p> <p>Nomination for the Nobel Prizes is by invitation only (except for the Nobel Peace Prize). The Nobel Committees sends confidential forms to persons who are qualified to nominate.

Previously, a person could be awarded a prize posthumously if he/she had already been nominated before 1 February of the same year, which was true of Erik Axel Karlfeldt (Nobel Prize in Literature 1931) and Dag Hammarskjöld (Nobel Peace Prize, 1961).</p> <p>Effective from 1974, the prize may only go to a deceased person to whom the prize was already awarded (usually in October), but who had died before he/she could receive the Prize on 10 December (William Vickrey, 1996 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel).</p> <p>See also paragraph 4 of the <a href="https://web.archive.org/web/20200526134452/https://www.nobelprize.org/about/statutes-of-the-nobel-foundation/">statutes</a> of the Nobel Foundation.</p> <p><strong>What about the rumours circling around the world about certain people being nominated for the Nobel Prize?</strong></p> <p>Well, either it’s just a rumour, or someone among the invited nominators has leaked information.

The foundation is a private institution that primarily manages the assets made available through the will of Alfred Nobel for the awarding of the Nobel Prize. The foundation also administers informational activities and arrangements surrounding the presentation of the prize. Every year we receive a great number of invitations to participate in or sponsor different projects, many of them deserving indeed, yet the foundation has been forced to develop a very strict policy of keeping apart from events that are not organised in direct relation to the work of the Nobel Foundation or of the prize-awarding institutions.</p> <p><strong>Who is the author of this site?</strong></p> <p>Nobel Media provides this web site primarily in support of the mission of the Nobel Foundation to spread information and knowledge about the Nobel Prize® and the Nobel Laureates.</p> <p><strong>Where can I get/buy Nobel posters?</strong></p> <p><em>Nobel posters for Physics, Chemistry and Economic Sciences</em><br/> Contact the reception desk at the Royal Swedish Academy of Sciences, e-mail <a href="https://web.archive.org/web/20200526134452/mailto:posters@kva.se">posters@kva.se</a>or order posters <a href="https://web.archive.org/web/20200526134452/https://www.kva.se/en/nobelaffischer">here</a>.
