Charcoal is the dark grey residue consisting of carbon, and any remaining ash, obtained by removing water and other volatile constituents from animal and vegetation substances. Charcoal is usually produced by slow pyrolysis, the heating of wood or other substances in the absence of oxygen (see pyrolysis, char and biochar). It is usually an impure form of carbon as it contains ash; however, sugar charcoal is among the purest forms of carbon readily available, particularly if it is not made by heating but by a dehydration reaction with sulfuric acid to minimise introducing new impurities, as impurities can be removed from the sugar in advance. The resulting soft, brittle, lightweight, black, porous material resembles coal.^[1]

Historically, production of wood charcoal in districts where there is an abundance of wood dates back to a very ancient period, and generally consists of piling billets of wood on their ends so as to form a conical pile, openings being left at the bottom to admit air, with a central shaft to serve as a flue. The whole pile is covered with turf or moistened clay. The firing is begun at the bottom of the flue, and gradually spreads outwards and upwards. The success of the operation depends upon the rate of the combustion. Under average conditions, 100 parts of wood yield about 60 parts by volume, or 25 parts by weight, of charcoal; small-scale production on the spot often yields only about 50%, large-scale was efficient to about 90% even by the seventeenth century. The operation is so delicate that it was generally left to colliers (professional charcoal burners).

The massive production of charcoal (at its height employing hundreds of thousands, mainly in Alpine and neighbouring forests) was a major cause of deforestation, especially in Central Europe. In England, many woods were managed as coppices, which were cut and regrew cyclically, so that a steady supply of charcoal would be available (in principle) forever; complaints (as early as the Stuart period) about shortages may relate to the results of temporary over-exploitation or the impossibility of increasing production to match growing demand. The increasing scarcity of easily harvested wood was a major factor for the switch to the fossil fuel equivalents, mainly coal and brown coal for industrial use.

The use of charcoal as a smelting fuel has been experiencing a resurgence in South America following Brazilian law changes in 2010 to reduce carbon emissions as part of President Lula da Silva's commitment to make a "green steel".^{[citation needed]}

The modern process of carbonizing wood, either in small pieces or as sawdust in cast iron retorts, is extensively practiced where wood is scarce, and also for the recovery of valuable byproducts (wood spirit, pyroligneous acid, wood tar), which the process permits. The question of the temperature of the carbonization is important; according to J. Percy, wood becomes brown at 220 °C (428 °F), a deep brown-black after some time at 280 °C (536 °F), and an easily powdered mass at 310 °C (590 °F).^{[citation needed]} Charcoal made at 300°C (572 °F) is brown, soft and friable, and readily inflames at 380 °C (716 °F); made at higher temperatures it is hard and brittle, and does not fire until heated to about 700 °C (1,292 °F).

In Finland and Scandinavia, the charcoal was considered the by-product of wood tar production. The best tar came from pine, thus pinewoods were cut down for tar pyrolysis. The residual charcoal was widely used as substitute for metallurgical coke in blast furnaces for smelting. Tar production led to rapid deforestation: it has been estimated all Finnish forests are younger than 300 years. The end of tar production at the end of the 19th century resulted in rapid re-forestation.

The charcoal briquette was first invented and patented by Ellsworth B. A. Zwoyer of Pennsylvania in 1897^[2] and was produced by the Zwoyer Fuel Company. The process was further popularized by Henry Ford, who used wood and sawdust byproducts from automobile fabrication as a feedstock. Ford Charcoal went on to become the Kingsford Company.

Production methods[link]

Charcoal has been made by various methods. The traditional method in Britain used a clamp. This is essentially a pile of wooden logs (e.g. seasoned oak) leaning against a chimney (logs are placed in a circle). The chimney consists of 4 wooden stakes held up by some rope. The logs are completely covered with soil and straw allowing no air to enter. It has to be lit by introducing some burning fuel into the chimney; the logs burn very slowly (cold fire) and transform into charcoal in a period of 5 days' burning. If the soil covering gets torn (cracked) by the fire, additional soil is placed on the cracks. Once the burn is complete, the chimney is plugged to prevent air from entering.^[3]

The last section of the film Le Quattro Volte (2010) gives a good and long, if poetic, documentation of the traditional method of making charcoal.^[4] The Arthur Ransome children's series Swallows and Amazons, (particular the second book Swallowdale), features carefully drawn vignettes of the lives and the techniques of charcoal burners at the turn of the century, in the Lake District of the UK.

Modern methods use a sealed metal container, as this does not have to be watched lest fire break through the covering.^{[citation needed]} However, on-site attendance is required. This is often carried out by the last forestry workers to live in working woodland in the western world. There has been a resurgence of this, particularly in the UK. A good example of this is Bulworthy Project where charcoal production supports an experiment in low-impact living and nature conservation.^[5]

The properties of the charcoal produced depend on the material charred and the charring temperature is also important. Charcoal contain varying amounts of hydrogen and oxygen as well as ash and other impurities which together with the structure determine the properties. The approximate composition of charcoal for gunpowders is sometimes empirically described as C₇H4O. In order to obtain a coal with high purity the source material should be free from non-volatile compounds (sugar can be used) and a high charring temperature used. After charring partial oxidation with oxygen or chlorine can be used to reduce the hydrogen levels. For activation of charcoal see activated carbon.

Types[link]

Binchōtan, Japanese high grade charcoal made from ubame oak

Ogatan, Charcoal briquettes made from sawdust

Commercial charcoal is found in either lump, briquette, or extruded forms:

• Lump charcoal is made directly from hardwood material and usually produces far less ash than briquettes.

• Briquettes are made by compressing charcoal, typically made from sawdust and other wood by-products, with a binder and other additives. The binder is usually starch. Some briquettes may also include brown coal (heat source), mineral carbon (heat source), borax, sodium nitrate (ignition aid), limestone (ash-whitening agent), raw sawdust (ignition aid), and other additives like paraffin or petroleum solvents to aid in ignition.^[6]
• Extruded charcoal is made by extruding either raw ground wood or carbonized wood into logs without the use of a binder. The heat and pressure of the extruding process hold the charcoal together. If the extrusion is made from raw wood material, the extruded logs are then subsequently carbonized.^{[citation needed]}
• Japanese charcoal removes pyroligneous acid during the charcoal making. Therefore when burning, there are almost no stimulating smells or smoke. The charcoal of Japan is classified into three kinds.
  • White charcoal (Binchōtan), It is very hard and having a metallic sound.
  • Black charcoal
  • Ogatan, Black charcoal that is made from hardened sawdust. Used in the Izakaya or Yakiniku restaurant.

The characteristics of charcoal products (lump, briquette, or extruded forms) vary widely from product to product. Thus it is a common misconception to stereotype any kind of charcoal, saying which burns hotter, etc.

• Activated carbon

Uses[link]

Charcoal has been used since the earliest times for a range of purposes including art and medicine, but by far its most important use has been as a metallurgical fuel. Charcoal is the traditional fuel of a blacksmith's forge and other applications where an intense heat is wanted. Charcoal was also used historically as a source of carbon black by grinding it up. In this form charcoal was important to early chemists and was a constituent of formulas for mixtures such as gunpowder. Due to its high surface area charcoal can be used as a filter, as a catalyst or as an adsorbent.

Metallurgical fuel[link]

Charcoal burns at intense temperatures, up to 2700 degrees Celsius. By comparison the melting point of iron is approximately 1200 to 1550 degrees Celsius. Due to its porosity it is sensitive to the flow of air and the heat generated can be moderated by controlling the air flow to the fire. For this reason charcoal is an ideal fuel for a forge and is still widely used by blacksmiths. Charcoal is also an excellent reducing fuel for the production of iron and has been used that way since Roman times. In the 16th century England had to pass laws to prevent the country from becoming completely denuded of trees due to production of iron. In the 19th century charcoal was largely replaced by coke, baked coal, in steel making due to cost. Charcoal is far superior fuel to coke, however, because it burns hotter and has no sulfur. Until World War II charcoal was still being used in Sweden to make ultra high-quality steel. In steel making charcoal is not only a fuel but also a source for the carbon in the steel.

Cooking fuel[link]

Prior to the industrial revolution charcoal was occasionally used as a cooking fuel. Modern "charcoal briquettes", widely used for outdoor grilling and barbecues in backyards and on camping trips, imitate this use, but are not actually charcoal.^[7] They are usually compacted mixtures of coal or coke and various binders.

Industrial fuel[link]

Historically, charcoal was used in great quantities for smelting iron in bloomeries and later blast furnaces and finery forges. This use was replaced by coke during the Industrial Revolution. For this purpose, charcoal in England was measured in dozens (or loads) consisting of 12 sacks or shems or seams, each of 8 bushels.^{[citation needed]}

Syngas production, automotive fuel[link]

Like many other sources of carbon charcoal can be used for the production of various syngas compositions, i.e. various CO+H2 + CO2 + N2 mixtures. The syngas is typically used as fuel, including automotive propulsion, or as a chemical feedstock.

In times of scarce petroleum, automobiles and even buses have been converted to burn wood gas (a gas mixture consisting primarily of diluting atmospheric nitrogen, but also containing combustible gasses, mostly carbon monoxide) released by burning charcoal or wood in a wood gas generator. In 1931 Tang Zhongming developed an automobile powered by charcoal, and these cars were popular in China until the 1950s. In occupied France during World War II, wood and wood charcoal production for such vehicles (called gazogènes) increased from pre-war figures of approximately fifty thousand tons a year to almost half a million tons in 1943.^[8]

Gunpowder[link]

Charcoal (mostly together with sulphur) is the fuel component of gunpowders and blasting powders and is also used in other pyrotechnic mixtures.^[9] This coal is usually made from specific hardwoods charred at low temperature.

Carbon source[link]

Charcoal may be used as a source of carbon in chemical reactions. One example of this is the production of carbon disulphide through the reaction of sulphur vapours with hot charcoal. In that case the wood should be charred at high temperature in order to reduce the residual amounts of hydrogen and oxygen that lead to side reactions.

Purification and filtration[link]

Activated carbon

Charcoal may be activated to increase its effectiveness as a filter. Activated charcoal readily adsorbs a wide range of organic compounds dissolved or suspended in gases and liquids. In certain industrial processes, such as the purification of sucrose from cane sugar, impurities cause an undesirable color, which can be removed with activated charcoal. It is also used to absorb odors and toxins in gases, such as air. Charcoal filters are also used in some types of gas masks. The medical use of activated charcoal is mainly the adsorption of poisons, especially in the case of suicide attempts in which the patient has ingested a large amount of a drug.^[10] Activated charcoal is available without a prescription, so it is used for a variety of health-related applications. For example, it is often used to reduce discomfort (and embarrassment) due to excessive gas in the digestive tract.^[11]

Animal charcoal or bone black is the carbonaceous residue obtained by the dry distillation of bones. It contains only about 10% carbon, the remainder being calcium and magnesium phosphates (80%) and other inorganic material originally present in the bones. It is generally manufactured from the residues obtained in the glue and gelatin industries. Its decolorizing power was applied in 1812 by Derosne to the clarification of the syrups obtained in sugar refining; but its use in this direction has now greatly diminished, owing to the introduction of more active and easily managed reagents. It is still used to some extent in laboratory practice. The decolorizing power is not permanent, becoming lost after using for some time; it may be revived, however, by washing and reheating. Wood charcoal also to some extent removes coloring material from solutions, but animal charcoal is generally more effective.^{[citation needed]}

Art[link]

Charcoal is used in art for drawing, making rough sketches in painting and is one of the possible media for making a parsemage. It must usually be preserved by the application of a fixative. Artists generally utilize charcoal in three forms:

• Vine charcoal is created by burning sticks of wood (usually willow or linden/Tilia) into soft, medium, and hard consistencies.^[12]
• Powdered charcoal is often used to "tone" or cover large sections of a drawing surface. Drawing over the toned areas will darken it further, but the artist can also lighten (or completely erase) within the toned area to create lighter tones.
• Compressed charcoal charcoal powder mixed with gum binder compressed into round or square sticks. The amount of binder determines the hardness of the stick.^[13] Compressed charcoal is used in charcoal pencils.

Horticulture[link]

One additional use of charcoal was rediscovered recently in horticulture. Although American gardeners have been using charcoal for a short while, research on Terra preta soils in the Amazon has found the widespread use of biochar by pre-Columbian natives to turn otherwise unproductive soil into very rich soil. The technique may find modern application, both to improve soils and as a means of carbon sequestration.^{[citation needed]}

Medicine[link]

Charcoal was consumed in the past as dietary supplement for gastric problems in the form of charcoal biscuits. Now it can be consumed in tablet, capsule or powder form, for digestive effects.^{[citation needed]} Research regarding its effectiveness is controversial.^[14]

Red colobus monkeys in Africa have been observed eating charcoal for the purposes of self-medication. Their leafy diets contain high levels of cyanide, which may lead to indigestion. So they learned to consume charcoal, which absorbs the cyanide and relieves indigestion. This knowledge about supplementing their diet is transmitted from mother to infant.^[15]

Also, see Activated charcoal, medicinal applications.

Smoking[link]

Special charcoals are used in smoking the hookah. Lit coals are placed on top of foil which is placed over the tobacco bowl; through indirect heat the coals "cook" the tobacco to a temperature that does not burn it but produces smoke.

Environmental implications[link]

Charcoal production at a sub-industrial level is one of the primary causes of deforestation in the Developing World. Charcoal production is usually illegal and nearly always unregulated as in Brazil where charcoal production is actually a huge illegal industry for making 'pig' iron^[16][17] Massive forest destruction has been documented in areas such as Virunga National Park in the Democratic Republic of Congo, where it is considered to be a primary threat to the survival of the mountain gorillas.^[18] Similar threats are found in Zambia.^[19]

Emma Charlotte Duerre Watson (born 15 April 1990) is an English actress and model.

Watson rose to prominence playing Hermione Granger in the Harry Potter film series. Watson was cast as Hermione at the age of nine, having previously acted only in school plays.^[2] From 2001 to 2011, she starred in all eight Harry Potter films alongside Daniel Radcliffe and Rupert Grint.^[3] Watson's work on the Harry Potter series has earned her several awards and more than £10 million.^[4] She made her modelling debut for Burberry's Autumn/Winter campaign in 2009.

In 2007, Watson announced her involvement in two productions: the television adaptation of the novel Ballet Shoes and an animated film, The Tale of Despereaux. Ballet Shoes was broadcast on 26 December 2007 to an audience of 5.2 million, and The Tale of Despereaux, based on the novel by Kate DiCamillo, was released in 2008 and grossed over US $86 million in worldwide sales.^[5][6]

Early life[link]

Emma Watson was born in Paris to Jacqueline Luesby and Chris Watson, both British lawyers.^[7][8] Watson has one French grandmother,^[9] and lived in Paris until the age of five. Following her parents' divorce, she moved with her mother and younger brother to Oxfordshire.^[7]

From the age of six, Watson had wanted to become an actress,^[10] and for a number of years she trained at the Oxford branch of Stagecoach Theatre Arts, a part-time theatre school where she studied singing, dancing and acting.^[11] By the age of ten, she had performed in various Stagecoach productions and school plays, including Arthur: The Young Years and The Happy Prince,^[12] but she had never acted professionally before the Harry Potter series. "I had no idea of the scale of the film series," she stated in a 2007 interview with Parade; "If I had I would have been completely overwhelmed."^[13]

Career[link]

Harry Potter[link]

In 1999, casting began for Harry Potter and the Philosopher's Stone (released as Harry Potter and the Sorcerer's Stone in the United States), the film adaptation of British author J. K. Rowling's best-selling novel. Casting agents found Watson through her Oxford theatre teacher,^[10] and producers were impressed by her confidence. After eight auditions, producer David Heyman told Watson and fellow applicants Daniel Radcliffe and Rupert Grint that they had been cast for the roles of the schoolfriends Hermione Granger, Harry Potter and Ron Weasley respectively. Rowling supported Watson from her first screen test.^[10]

The release of Harry Potter and the Philosopher's Stone in 2001 was Watson's debut screen performance. The film broke records for opening-day sales and opening-weekend takings and was the highest-grossing film of 2001.^[14][15] Critics praised the performances of the three leads, often singling out Watson for particular acclaim; The Daily Telegraph called her performance "admirable",^[16] and IGN said she "stole the show".^[17] Watson was nominated for five awards for her performance in Philosopher's Stone, winning the Young Artist Award for Leading Young Actress.^[18]

A year later, Watson again starred as Hermione in Harry Potter and the Chamber of Secrets, the second instalment of the series. Reviewers praised the lead actors' performances. The Los Angeles Times said Watson and her peers had matured between films,^[19] while The Times criticised director Chris Columbus for "under-employing" Watson's hugely popular character.^[20] Watson received an Otto Award from the German magazine Bravo for her performance.^[21]

Watson at the premiere of Goblet of Fire in November 2005

In 2004, Harry Potter and the Prisoner of Azkaban was released. Watson was appreciative of the more assertive role Hermione played, calling her character "charismatic" and "a fantastic role to play".^[22] Although critics panned Radcliffe's performance, labelling him "wooden", they praised Watson; The New York Times lauded her performance, saying "Luckily Mr. Radcliffe's blandness is offset by Ms. Watson's spiky impatience. Harry may show off his expanding wizardly skills ... but Hermione ... earns the loudest applause with a decidedly unmagical punch to Draco Malfoy's deserving nose."^[23] Although Prisoner of Azkaban remains the lowest-grossing Harry Potter film as of April 2009, Watson's personal performance won her two Otto Awards and the Child Performance of the Year award from Total Film.^[24][25][26]

With Harry Potter and the Goblet of Fire (2005), both Watson and the Harry Potter film series reached new milestones. The film set records for a Harry Potter opening weekend, a non-May opening weekend in the US, and an opening weekend in the UK. Critics praised the increasing maturity of Watson and her teenage co-stars; the New York Times called her performance "touchingly earnest".^[27] For Watson, much of the humour of the film sprang from the tension among the three lead characters as they matured. She said, "I loved all the arguing. ... I think it's much more realistic that they would argue and that there would be problems."^[28] Nominated for three awards for Goblet of Fire, Watson won a bronze Otto Award.^[29][30][31] Later that year, Watson became the youngest person to appear on the cover of Teen Vogue,^[32] an appearance she reprised in August 2009.^[33] In 2006, Watson played Hermione in The Queen's Handbag, a special mini-episode of Harry Potter in celebration of Queen Elizabeth II's 80th birthday.^[34]

Watson at the premiere of Half-Blood Prince in July 2009

The fifth film in the Harry Potter franchise, Harry Potter and the Order of the Phoenix, was released in 2007. A huge financial success, the film set a record worldwide opening-weekend gross of $332.7 million.^[35] Watson won the inaugural National Movie Award for Best Female Performance.^[36] As the fame of the actress and the series continued, Watson and fellow Harry Potter co-stars Daniel Radcliffe and Rupert Grint left imprints of their hands, feet and wands in front of Grauman's Chinese Theater in Hollywood on 9 July 2007.^[37]

By July 2007, Watson's work in the Harry Potter series was said to have earned her more than £10 million, and she acknowledged she would never have to work for money again.^[4] In March 2009, she was ranked 6th on the Forbes list of "Most Valuable Young Stars",^[38] and in February 2010, she was named as Hollywood's highest paid female star, having earned an estimated £19 million in 2009.^[39]

Despite the success of Order of the Phoenix, the future of the Harry Potter franchise became surrounded in doubt, as all three lead actors were hesitant to sign on to continue their roles for the final two episodes.^[40] Radcliffe eventually signed for the final films on 2 March 2007,^[40] but Watson was considerably more hesitant.^[41] She explained that the decision was significant, as the films represented a further four-year commitment to the role, but eventually conceded that she "could never let [the role of] Hermione go",^[42] signing for the role on 23 March 2007.^[43] In return for committing to the final films, Watson's pay was doubled to £2 million per film;^[44] she concluded that "in the end, the pluses outweighed the minuses".^[13] Principal photography for the sixth film began in late 2007, with Watson's part being filmed from 18 December to 17 May 2008.^[45][46]

Harry Potter and the Half-Blood Prince premiered on 15 July 2009,^[47] having been delayed from November 2008.^[48] With the lead actors now in their late teens, critics were increasingly willing to review them on the same level as the rest of the film's all-star cast, which the Los Angeles Times described as "a comprehensive guide to contemporary UK acting".^[49] The Washington Post felt Watson to have given "[her] most charming performance to date",^[50] while The Daily Telegraph described the lead actors as "newly-liberated and energised, eager to give all they have to what's left of the series".^[51]

Watson's filming for the final instalment of the Harry Potter series, Harry Potter and the Deathly Hallows, began on 18 February 2009^[52] and ended on 12 June 2010.^[53] For financial and scripting reasons, the original book has been divided into two films which were shot consecutively.^[54][55] Harry Potter and the Deathly Hallows part 1 was released in November 2010 while the second film was released in July 2011.

Other acting work[link]

Watson's first non-Potter role was the 2007 BBC film Ballet Shoes, an adaptation of the novel of the same title by Noel Streatfeild.^[56][57] The film's director Sandra Goldbacher commented that Watson was "perfect" for the starring role of aspiring actress Pauline Fossil: "She has a piercing, delicate aura that makes you want to gaze and gaze at her."^[58] Ballet Shoes was broadcast in the UK on Boxing Day 2007 to an audience of 5.7 million viewers, to mixed reviews.^{[59][60][61][62][63]} Watson also lent her voice to the role of Princess Pea in the animated film The Tale of Despereaux, a children's comedy starring Matthew Broderick with Harry Potter co-star Robbie Coltrane (playing the character of Rubeus Hagrid) also starring in the film.^[64] The Tale of Despereaux was released in December 2008 and grossed $87 million worldwide.^[5] In December 2008, Watson stated she wanted to go to university after she completed the Potter series.^[65]

In May 2010, Watson was reported to be in talks to star in a film adaptation of The Perks of Being a Wallflower.^[66] Filming began in summer 2011.^[67] Also that month, she announced that she would appear in a music video for One Night Only after meeting lead singer George Craig at the 2010 Winter/Summer Burberry advertising campaign. The video, "Say You Don't Want It", was screened on Channel 4 on 26 June 2010 and released on 16 August.^[68] In her first post-Harry Potter film, Watson appeared in 2011's My Week with Marilyn as Lucy, a wardrobe assistant who has a few dates with the main character, Colin Clark.^[69][70] Watson has also expressed interest in being in a musical film.^[71]

Modelling[link]

In 2008, the British press reported that Watson was to replace Keira Knightley as the face of the fashion house Chanel, but this was denied by both parties.^[72][73] In June 2009, following several months of rumours, Watson confirmed that she would be partnering with Burberry as the face of their Autumn/Winter 2009 campaign, for which she received an estimated six-figure fee.^[74][75][76] She also appeared in Burberry's 2010 Spring/Summer campaign alongside her brother Alex, musicians George Craig and Matt Gilmour, and model Max Hurd.^[77] In February 2011, Watson was awarded the Style Icon award from British Elle by Dame Vivienne Westwood.^[78][79] Watson continued her involvement in fashion advertising when she announced she had been chosen as the face of Lancôme in March 2011.^[80]

In September 2009, Watson announced her involvement with People Tree, a Fair Trade fashion brand.^[81] Watson worked as a creative advisor for People Tree to create a spring line of clothing, which was released in February 2010;^[81][82] the range featured styles inspired by southern France and London.^[82][83] The collection, described by The Times as "very clever" despite their "quiet hope that [she] would become tangled at the first hemp-woven hurdle",^[84] was widely publicised in magazines such as Teen Vogue,^[85] Cosmopolitan, and People. Watson, who was not paid for the collaboration,^[86] admitted that competition for the range was minimal,^[84] but argued that "Fashion is a great way to empower people and give them skills; rather than give cash to charity you can help people by buying the clothes they make and supporting things they take pride in";^[87] adding, "I think young people like me are becoming increasingly aware of the humanitarian issues surrounding fast fashion and want to make good choices but there aren't many options out there."^[84] Watson continued her involvement with People Tree, resulting in the release of a 2010 Autumn/Winter collection.^[88]

Personal life[link]

After moving to Oxford with her mother and brother, Watson attended The Dragon School until June 2003 and then moved to Headington School, also in Oxford.^[7] While on film sets, Watson and her peers were tutored for up to five hours a day.^[89] In June 2006, Watson took GCSE examinations in 10 subjects, achieving eight A* and two A grades.^[7][90]

After leaving school, Watson took a gap year^[91] to film Harry Potter and the Deathly Hallows beginning in February 2009,^[55] but said she "definitely want[ed] to go to university".^[65] The Providence Journal reported that Watson had confirmed that she had chosen Brown University, located in Providence, Rhode Island.^[92][93] In March 2011, after 18 months at the university, Watson announced that she was deferring her course for "a semester or two",^[94] to give her more time to participate in the advertising buildup for the release of the second Deathly Hallows film, and other projects.^[95] Watson will complete her final year at Brown University in 2012.^[96]

Watson supports the Wild Trout Trust.^{[97][dead link]}
