Question: What was the field of work of the scientist who used to be on the £10 note?

full_context: Document 1: Herschel Medal: The Herschel Medal is awarded by the Royal Astronomical Society (RAS) for "investigations of outstanding merit in observational astrophysics". It is awarded for a single piece of work so that younger scientists can be candidates for the award. It is named after the RAS's first president, William Herschel. The medal was first awarded in 1974. The medal has been shared twice, in 1977 and 1986. It has been awarded 22 times to a total of 24 people (23 men, one woman), mostly from the UK.
Document 2: Cantor medal: The Cantor medal of the Deutsche Mathematiker-Vereinigung is named in honor of Georg Cantor, the first president of the DMV. It is awarded at most every second year during the yearly meetings of the society. The prize winners are mathematicians who are associated with the German language.
Document 3: Darwin Medal: The Darwin Medal is awarded by the Royal Society every alternate year for "work of acknowledged distinction in the broad area of biology in which Charles Darwin worked, notably in evolution, population biology, organismal biology and biological diversity". First awarded in 1890, it was created in memory of Charles Darwin and is presented with a £2000 prize (as of 2016).
Document 4: Darwin Awards: The project became more formalized with the creation of a website in 1993, and followed up by a series of books starting in 2000, authored by Wendy Northcutt. The criterion for the awards states, "In the spirit of Charles Darwin, the Darwin Awards commemorate individuals who protect our gene pool by making the ultimate sacrifice of their own lives. Darwin Award winners eliminate themselves in an extraordinarily idiotic manner, thereby improving our species' chances of long-term survival."
Document 5: Bank of England £20 note: Twenty pound notes were introduced by the Bank of England for the first time in 1725. The earliest notes were handwritten, and were issued to individuals as needed. These notes were written on one side only and bore the name of the payee, the date, and the signature of the issuing cashier. With the exception of the Restriction Period between 1797 and 1821 when the French Revolutionary Wars and the Napoleonic Wars caused a bullion shortage, these notes could be exchanged in full, or in part, for an equivalent amount of gold when presented at the bank. If redeemed in part, the banknote would be signed to indicate the amount that had been redeemed. From 1853 printed notes replaced handwritten notes, with the declaration ``I promise to pay the bearer on demand the sum of twenty pounds ''replacing the name of the payee. This declaration remains on Bank of England banknotes to this day. A printed signature of one of three cashiers appeared on the printed notes, though this was replaced by the signature of the Chief Cashier from 1870 onward.
Document 6: Price Medal: Price Medal is a medal of the Royal Astronomical Society, for investigations of outstanding merit in solid-earth geophysics, oceanography, or planetary sciences. The medal is named after Albert Thomas Price. It was first awarded in 1994 and was initially given every three years. In 2005 this switched to every two years, and from 2014 it has been awarded every year.
Document 7: Bank of England £5 note: The Bank of England £5 note, also known as a fiver, is a banknote of the pound sterling. It is the smallest denomination of banknote issued by the Bank of England. In September 2016, a new polymer note was introduced, featuring the image of Queen Elizabeth II on the obverse and a portrait of Winston Churchill on the reverse. The old paper note, first issued in 2002 and bearing the image of prison reformer Elizabeth Fry on the reverse, was phased out and ceased to be legal tender after 5 May 2017.
Document 8: Banknotes of the pound sterling: In 2012 Northern Bank adopted the name of its Copenhagen - based parent company Danske Bank Group and rebranded its retail banking operation. In June 2013 the bank issued a new series of £10 and £20 notes bearing the new brand name; at the same time it also announced that it would cease production of £50 and £100 notes. Older notes bearing the Northern Bank name will continue in circulation for some time as they are gradually withdrawn, and remain acceptable forms of payment. In spite of the Danish name on the new notes, banknotes issued by Danske Bank are sterling notes and should not be confused with banknotes of the Danish krone issued by the Danmarks Nationalbank, Denmark's central bank.
Document 9: Isaac Newton: From 1978 until 1988, an image of Newton designed by Harry Ecclestone appeared on Series D £1 banknotes issued by the Bank of England (the last £1 notes to be issued by the Bank of England). Newton was shown on the reverse of the notes holding a book and accompanied by a telescope, a prism and a map of the Solar System.
Document 10: Bank of England £10 note: In December 2013 the Bank of England announced that the next £10 note would be printed on polymer, rather than cotton paper. This followed the announcement in July 2013 that Charles Darwin would be replaced by 19th Century author Jane Austen on the next £10 note, which would enter circulation in 2017. The decision to replace Darwin with Austen followed a campaign to have a woman on the back of a Bank of England banknote when it was announced that the only woman to feature on the back of a note -- prison reformer Elizabeth Fry on the £5 note -- was to be replaced by Winston Churchill. Images on the reverse of the Jane Austen note include a portrait of Austen commissioned by her nephew, an illustration of Elizabeth Bennet from Pride and Prejudice by Isabel Bishop, an image of Godmersham Park (the home of Austen's brother), and a design based on Austen's 12 - sided writing table as used by her at Chawton Cottage. The note also includes the quote ``I declare after all there is no enjoyment like reading! ''which is said by Austen's character Caroline Bingley, who in fact has no interest in reading and is attempting to impress Mr Darcy.
Document 11: One pound (British coin): The original, round £1 coin replaced the Bank of England £1 note, which ceased to be issued at the end of 1984 and was removed from circulation on 11 March 1988, though still redeemable at the Bank's offices, like all English banknotes. One - pound notes continue to be issued in Jersey, Guernsey and the Isle of Man, and by the Royal Bank of Scotland, but the pound coin is much more widely used. A new, dodecagonal (12 - sided) design of coin was introduced on 28 March 2017 and both new and old versions of the one pound coin circulated together until the older design was withdrawn from circulation on 15 October 2017. After that date, the older coin could only be redeemed at banks, although some retailers announced they would continue to accept it for a limited time. The original round pound remains legal tender on the Isle of Man.
Document 12: GlaxoSmithKline Prize: The GlaxoSmithKline Prize and Lecture is awarded by the Royal Society of London "for original contributions to medical and veterinary sciences published within ten years from the date of the award". Sponsored by GlaxoSmithKline, the medal is awarded with a gift of £2500. The medal was first awarded in 1980 to César Milstein "in recognition of his pioneering the production of monoclonal antibodies from hybrid cell lines and initiating their application worldwide in many fields of biology and medicine", and has since been awarded 13 times.
Document 13: United States ten-dollar bill: In 2015, the Treasury Secretary announced that the obverse portrait of Hamilton would be replaced by the portrait of an as yet undecided woman, starting in 2020. However, due to the surging popularity of Hamilton, a hit Broadway musical based on Hamilton's life, in 2016 this decision was reversed and Hamilton will remain on the $10 bill, and instead a woman will appear on the $20 bill.
Document 14: Max Born Medal and Prize: The Max Born Medal and Prize is a scientific prize awarded yearly by the German Physical Society (DPG) and the British Institute of Physics (IOP) in memory of the German physicist Max Born. The terms of the award are that it is "to be presented for outstanding contributions to physics". The award goes to physicists based in Germany and in the UK or Ireland in alternate years.
Document 15: Bank of England £50 note: Fifty pound notes were introduced by the Bank of England for the first time in 1725. The earliest notes were handwritten and were issued as needed to individuals. These notes were written on one side only and bore the name of the payee, the date, and the signature of the issuing cashier. With the exception of the Restriction Period between 1797 and 1821, when the French Revolutionary Wars and the Napoleonic Wars caused a bullion shortage, these notes could be exchanged in full, or in part, for an equivalent amount of gold when presented at the bank. If redeemed in part, the banknote would be signed to indicate the amount that had been redeemed. From 1853 printed notes replaced handwritten notes, with the declaration ``I promise to pay the bearer on demand the sum of fifty pounds ''replacing the name of the payee. This declaration remains on Bank of England banknotes to this day. A printed signature of one of three cashiers appeared on the printed notes, although this was replaced by the signature of the Chief Cashier from 1870 onward.
