The nautical compass is used for determining directions, using a free moving magnetised needle, indicating north and south. This is a medium sized compass and was suitable for mounting in a fixed brass binnacle or a portable wooden box. The compass fluid was typically lamp oil, or a mixture of alcohol and water. This compass, based on its pattern, was probably manufactured around the 1930s. The compass’s maker, Bergen Nautik, was a 20th Century compass manufacturer, making compasses from the 1900s but no longer in business.The factory was located in Hordaland County, Bergen, on the west coast of Norway. This compass is not a very significant marine item as it was made in the 20th century. Examples of the same compass that have been salvaged can be purchased today mounted either in a wooden box or a brass pedestal.Compass; marine or ship's compass, brass, gimbal mounting, in blue metal casing.

Negretti and Zambra 1850-1980s were optical instrument makers and mathematical instrument makers based in London, England. The firm of Negretti and Zambra was established in 1850 by Henry Negretti and Joseph Zambra who had formed a partnership. Their skill was immediately apparent when exhibiting at the 1851 Great Exhibition at Hyde Park, they were the only English instrument makers to receive a prize medal for meteorological instruments, resulting in their appointment as instrument makers to the queen, Greenwich observatory, and the British Meteorological Society. In 1853, when the Crystal Palace was re-erected in Sydenham, Negretti and Zambra became the official photographers of the Crystal Palace Company, which allowed them to photograph the interior and grounds of the new building. The firm made use of this access to produce a number of stereographs. Between 1855 and 1857 Negretti and Zambra commissioned photographer Pierre Rossier to travel to China to document the Second Opium War. Although Rossier subsequently was unable to accompany to Anglo-French forces in that campaign, he nevertheless produced a number of stereographs and other photographs of China, Japan, the Philippines and Siam (now Thailand), which Negretti and Zambra published and that represented the first commercial photographs of those countries. In 1856 Negretti and Zambra sponsored a photographic expedition to Egypt, Nubia and Ethiopia conducted by Francis Firth. In 1864 Negretti and Zambra (themselves) photographed Shakespeare's House at Stratford on Avon. A sepia photograph was then pasted onto card 4" × 2.5". This was then presented to visitors to the Crystal Palace to enable them to compare it with the model erected by Mr E. T. Parr in the Centre Transept. The card itself is headed "Crystal Palace April 23rd 1864." That year they also published a book, titled A Treatise on Meteorological Instruments, (which was reprinted in 1995). Throughout World War One Negretti and Zambra were entirely engaged in the production of various instruments for the Ministry of Munitions. They developed many instruments for the Air Ministry including a mercury-in-steel distance thermometer for taking the oil and air temperatures in aircraft which was patented in 1920. In 1946 the company went private and in 1948 the company was made public, and by 1950 Negretti and Zambra had 821 employees in Britain. In order to increase production and to safeguard future development in 1964, they purchased a modern factory at Aylesbury for all their production. In 1981 Negretti and Zambra were taken over by a group of financial institutions in the form of Western Scientific Instruments and in 1985 the company was acquired by Meggitt Holdings.The subject compass is just one type of the many marine and scientific, optical items this company produced over it’s life time. Negretti and Zambra were prolific manufactures of types of items as well as being very prominent in photography pioneering new innervation's and sponsoring expeditions to little known countries to document peoples daily lives and culture through photography.Azimuth compass on tripod in a fitted wooden box with a round spirit level included, lid of box has three indented circles where the legs of the compass fit when it is set up for use.

Henry Browne and Son Ltd, of Barking, made aviation and nautical compasses, clocks and dials. The company made compasses for aircraft notably, Spitfires, Tiger moths and Concord. Henry Browne was born in Lewis, Sussex in 1842 and died in Barking in 1935. His company was a well respected English instrument maker that had been making and selling fine quality compasses, ship's clocks, inclinometers, sextants, and chandlery items for over 140 years. It started in a factory in Brightlingsea, Essex and moved to Barking in 1929. The Trade Mark brand Sestrel was used on all their equipment. Their “Dead Beat“ compass design is well dampened serving to reduce oscillations. It is reported that this design compass was fitted to many Allied ships during WW II. The company went through a boom period in the 1970s but collapsed in the 1980s due to the popularity of cheaper plastic compasses over tradition brass ones. Over more recent years, there has been a consolidation of British instrument makers and the firm of Henry Browne & Son has changed hands a number of times. At last count, it became part of Lillie & Gillie of London in 1985 when John Lilley & Gillie Ltd acquires the assets of Henry Browne & Sons (Sestrel) Ltd, a major competitor for what may be the second time. The model name of Sestral came about via the following.Take first two letters of the word Sensitive then the firs two letter of steady and the firs three letters of reliable hence the trade name of "Sestral".

The John E. Hand & Sons Company was founded in Philadelphia in 1873, quickly gaining a reputation as competent manufacturers of nautical instruments and compass adjusters. In fact, John Enos Hand, the company founder, is recognised as the first man in America to adjust a compass aboard an iron ship. The Hand Company built navigational equipment for all varieties of floating vessels, and operated a chain of retail outlets with “service stations” in numerous port cities, including Baltimore and New Orleans, until 1956. Service stations sold Hand instruments as well as other nautical paraphernalia and provided compass adjusting services. Additionally, John E Hand and his two sons, John L Hand and Bartram Hand, were inventors in their own right who patented design improvements for numerous instruments that were employed in the company’s work. Commercial and private contracts dominated the firm’s business until the late 1930s when the United States military began preparations for World War II. Although the Hand Company never completely abandoned its involvement with private industry, after World War II, military contracts monopolised their business. The Company obtained contracts with the Navy, Coast Guard and Marines to develop new instruments, and to build military-engineered nautical equipment. Of note are the wrist compass, developed for the Navy beginning in the 1950s, and the Mark VII Model 5 Navy Standard Binnacle. Although it moved numerous times, the Hand Company headquarters and factory remained in the Delaware Valley, occupying several buildings in Philadelphia and southern New Jersey. Maintaining its central office in Philadelphia well into the 1900s, the factory was moved to Atco, New Jersey around the turn of the twentieth century and subsequently to Haddon field, New Jersey. It moved one last time in the 1960s to Cherry Hill, New Jersey. In 1997, California-based Sunset Cliffs Merchandising Corporation purchased the Hand Company and all its assets for $100,000.

Mr John Wilson Gillie was born on the 31st of March 1864. On the 31st of July 1880 he was apprenticed for four years to J.J. Wilson and Sons, Nautical Instrument Makers of Sunderland. Following the apprenticeship he spent six months to a year as an ‘improver’ in Glasgow, and then started a new company ‘Wilson and Gillie’ in North Shields. At this time sail had just given way to steam and wooden ships to steel, and the railways were competing with colliers for the carrying of coal from the North East of England to London and the South. In 1858 only seven out of 44 shipyards on the Tyne were using iron, but by 1862 there were ten, employing around 4,000 men. These changes had a significant effect on nautical instrument manufacturers, as the magnetic compass for a wooden sailing vessel was very simple and required little in the way of compensation. For steel vessels much more was required and this was a period of great development, both in the compass bowl and the binnacle in which it was housed. In 1870 Sir William Thomson (later Lord Kelvin) designed his dry card standard compass, which completely replaced all previous designs. Wilson and Gillie started as agents for the Thomson compass, but later J.W. Gillie, using similar principles, redesigned the compass suspension and patented the ‘UNIT’ standard compass. It became popular with local shipowners and shipbuilders. In 1910 the firm of John Lilley and Son (which had been established in London in 1812), found themselves in financial difficulties and were saved with the help of John Wilson Gillie, who established, on the 8th of August 1911, a new firm of John Lilley and Son Limited. John Lilley and Son had been the sole London agents for Sir William Thomson, a very enviable position during this period, when the Thomson compass led the field. Unfortunately, Mr. Lilley had quarreled with the Glasgow company, who withdrew the agency and established their own branch in London (later to become Kelvin White and Hutton). On November 7th 1913, the firm of John Lilley and Son Limited of London amalgamated with Wilson and Gillie of North Shields, and after this date instruments manufactured by the two companies bore the name John Lilley and Son Limited of London and North Shields. During the 1930s many of the London nautical instrument makers were in difficulties, including John Lilley and Son Limited and Reynolds and Son, Dobbie and Clyde Limited, and Mr. J.W. Gillie arranged an amalgamation between these two companies. The new firm became Lilley and Reynolds Limited. In 1943, with estate duties in mind, the North Shields company was reconstituted and took the name of John Lilley and Gillie Limited, although the shareholders, directors and personnel remained unchanged In the early 1970s Lilley and Gillie developed close links with Observator in Rotterdam, who manufactured one of the first fully reliable transmitting magnetic compass systems. The Observator shareholders, Holland America Line, bought the share capital of John Lilley and Gillie Limited., but retained all the personnel and the directors. (See Links for more information)A significant item of early 20th century marine navigational equipment made by a leading manufacturer in the field from a company that is still producing marine navigational instruments today. John Lilleys company began in 1812 growing at a time when the transition of compasses from timber ships, to steel vessels. Compasses at this time required a method of compensation to allow their inclusion in steel vessels without magnetic deviation. This therefore was a period of great development, both in the compass bowl and the binnacle in which it was housed and the Lilley company were leaders in the field. Ships binnacle, wood with brass fittings, consists of 2 brass lamp holders, place for compass, Also has an inclinometer with a scale 40 to 0 to 40, one red and one green iron Kelvin compensation balls, one on each side of binnacle denoting port and starboard, a brass cylinder attached perpendicular at the rear for storing a Flinders Bar, 2 hinged cupboards containing adjustable wooden racks with drilled holes in them to hold iron Heeling error magnets.Textured brass plate attached to front stating "JOHN LILLEY & SON LTD (WILSON & GILLIE), NAUTICAL INSTRUMENT MAKERS, NORTH SHIELDS" .

In 1941, the scientific instrument manufacturing firms of  Henry Hughes & Son Ltd, London, England, and  Kelvin Bottomley & Baird Ltd, Glasgow, Scotland, came together to form Kelvin & Hughes Ltd. Kelvin Company History: The origins of the company lie in the highly successful and strictly informal relationship between William Thomson (1824-1907), Professor of Natural Philosophy at Glasgow University from 1846-1899 and James White, a Glasgow optical maker. James White (1824-1884) founded the firm of James White, an optical instrument maker in Glasgow in 1850 and was involved in supplying and mending apparatus for Thomson university laboratory and working with him on experimental constructions. White was declared bankrupt in August 1861 and released several months later. In 1870, White was largely responsible for equipping William Thomson laboratory in the new University premises at Gilmore hill. From 1876, he was producing accurate compasses for metal ships to Thomson design during this period and this became an important part of his business in the last years of his life. He was also involved in the production of sophisticated-sounding machinery that Thomson had designed to address problems encountered laying cables at sea, helping to make possible the first transatlantic cable connection. At the same time, he continued to make a whole range of more conventional instruments such as telescopes, microscopes and surveying equipment. White's association with Thomson continued until he died. After his death, his business continued under the same name, being administered by Matthew Edwards (until 1891 when he left to set up his own company. Thomson who became Sir William Thomson and then Baron Kelvin of Largs in 1892, continued to maintain his interest in the business after James White's death. In 1884 raising most of the capital needed to construct and equip new workshops in Cambridge Street, Glasgow. At these premises, the company continued to make the compass Thomson had designed during the 1870s and to supply it in some quantity, especially to the Admiralty. At the same time, the firm became increasingly involved in the design, production and sale of electrical apparatus. In 1899, Lord Kelvin resigned from his University chair and became, in 1900, a director in the newly formed limited liability company Kelvin & James White Ltd which had acquired the business of James White. At the same time Kelvin's nephew, James Thomson Bottomley (1845-1926), joined the firm. In 1904, a London branch office was opened which by 1915 had become known as Kelvin, White & Hutton Ltd. Kelvin & James White Ltd underwent a further change of name in 1913, becoming Kelvin Bottomley & Baird Ltd. Hughes Company History: Henry Hughes & Sons were founded in 1838 in London as a maker of chronographic and scientific instruments. The firm was incorporated as “Henry Hughes & Sons Ltd” in 1903. In 1923, the company produced its first recording echo sounder and in 1935 a controlling interest in the company was acquired by S Smith & Son Ltd resulting in the development and production of marine and aircraft instruments. Following the London office's destruction in the Blitz of 1941, a collaboration was entered into with Kelvin, Bottomley & Baird Ltd resulting in the establishing “Marine Instruments Ltd”. Following the formal amalgamation of Kelvin, Bottomley & Baird Ltd and Henry Hughes & Sons Ltd in 1947 to form Kelvin & Hughes Ltd. Marine Instruments Ltd then acted as regional agents in the UK for Kelvin & Hughes Ltd who were essentially now a part of Smith's Industries Ltd founded in 1944 and the successors of S. Smith & Son Ltd. Kelvin & Hughes Ltd went on to develop various marine radar and echo sounders supplying the Ministry of Transport, and later the Ministry of Defence. The firm was liquidated in 1966 but the name was continued as Kelvin Hughes, a division of the Smiths Group. In 2002, Kelvin Hughes continues to produce and develop marine instruments for commercial and military. G. Falconer Company History: G Falconer (Hong Kong Ltd) appear to have had a retail presence in Hong Kong since 1885, according to the company website, and currently have a shop in the Peninsula Hotel. G Falconer was the Hong Kong selling agent for several British companies. Ross Ltd of 111 New Bond St London was one and the other was Kelvins Nautical Instruments. Falconers were primarily watchmakers, jewellers and diamond merchants.They were also agents for Admiralty Charts, Ross binoculars and telescopes, and sold English Silverware and High Class English Jewellery. In 1928 the company was operating from the Union Building opposite the Hong Kong general post office. It is unclear if the item is an original Sextant made by Kelvin prior to his amalgamation with Henry Hughes & Sons in 1941 as Kelvin appears to have only made compasses up to this date. If the Sextant can be established that it was made by Kelvin then it is very significant and a rare item made for and distributed through their Hong Kong selling agents G Falconer Ltd. There are many Sextants advertised for sale stating "Kelvin & Hughes 1917 model sextant". These can be regarded as replicas as the company was not formed until 1941 and production of marine instruments was not fully under way until after the war in 1947. Further investigation needs to be undertaken to accurately determine the provenance of this item. As the writer currently has the impression that the subject object was possibly made by Kelvin and Hughes in the mid to late 20th century or is a replica made by an unknown maker in the late 1970s. Purchased as an exhibition of marine navigational instruments for the Flagstaff Hill museum. The Sextant is a brass apparatus with filters and telescope lens, and comes with a wooden felt lined storage box. It is a doubly reflecting navigation instrument that measures the angular distance between two visible objects. The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation.G Falconer and Co.

This magnetic compass is a good size to fit easily into a person's pocket or personal luggage and is protected from knocks by its wooden case. It could have been used for reference when travelling on land or sea. There is no visible manufacturer's mark, which may mean that it was not of high monetary value. Leith is a district of Edinburgh in the country of Scotland, the U.K. It was once the Port of Edinburgh and many migrant ships departed from here bound for the Australian colony. It had a busy shipbuilding industry, with wet and dry docks. It appears from the inscription on the case "Chas Gray, LEITH, 1839" that this pocket compass once belonged to Charles M. Gray (Chas is a common abbreviation for the name Charles). The inscription coincides with the name, place and date that the Western Victorian pioneer Charles M. Gray left Scotland and arrived in Australia. Charles Gray was born in Anstruther, Scotland, in 1818. His family was connected with the Royal Marines, which may have created his nautical instruments such as this pocket compass. Charles Gray arrived in Hobson's Bay on 15 June 1839 on the ship “Midlothian”. That same ship had departed from Leith, Scotland on February 15th 1839. Did Charles Gray acquire the pocket compass in Leith, perhaps as a gift or a souvenir of his motherland? Charles Gray was an early squatter and went on to become a very successful settler as a sheep pastoralist in the Western District of what is now Victoria (originally the colony of New South Wales). He and his wife had a large property called “Nareeb Nareeb”, Green Hill Creek District (now Glenthompson), Victoria, from 1840-1886. He was also a local Councillor and Justice of the Peace, and had an interest in the local indigenous people; he named his property after their tribe. Charles returned to England in 1890 and died there in 1905. Charles Gray had written an account in 1890 of his life at Nareeb Nareeb, called Western Victoria in the Forties: "REMINISCENCES OF A PIONEER The Western District in the 1840's By Charles Gray" , a valuable historical reference to colonial Victoria. His book was published by the Hamilton Spectator in 1932. Charles Gray's photograph is one of 713 historical photographs of early Victorian settlers, created as a montage by Thomas Foster Chuck in 1872. The State Library of Victoria holds the framed montage titled “The Explorers and Early Colonists of Victoria”. To qualify for inclusion on this montage the Settlers must have arrived in Victoria before 1843. Charles Gray's photograph is number 349! The pocket compass is associated with Charles Gray, one of the early squatters and settlers in Western Victoria, possibly given to him as a parting gift on his emigration to Van Diemans land in 1839. The item is very significant as it's connection with one of Victoria's early pioneers is well provenanced by the inscriptions on the wooden case. Pocket compass, brass, set into a square wooden case with hinged lid and small hook catch. Compass is marked with 360 degrees and compass points and has two pointers; one to show magnetic north and one to set the direction of travel. Hinges are triangular and inset into the wood. The lid has an attached brass plaque with the inscription "Chas Gray, Leith, 1839" (It likely belonged to Charles Gray, Leith, UK, who migrated to Port Philip Australia in 1839 and became a successful pastoralist.) “Chas Gray / LEITH / 1839” engraved on brass plaque on lid.flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, magnetic compass, pocket compass, charles m. gray, chas gray, migrrant from leith 1839, charles gray anstruther, scottland, ship midlothian 1839, squatter western victoria, settler western victoria, hobson's bay port phillip australia, charles gray nareeb nareeb - green hill creek district, western victoria in the forties: reminiscences of a pioneer by charles m. gray 1890, leith edinburgh u.k., western victoria in the forties: reminiscences of a pioneer - montage by thomas foster chuck 1872, charles gray, reminiscences of a pioneer, the western district in the 1840's, compass, scientific instrument, nautical instrument, direction, directional compass, navigation

Tug Melbourne: The barometer was salvaged from a 496-ton tug that had been built in 1952 and had sunk in Port Philip Bay on the 9th of August 1972 after a collision with the SS Nieuw Holland, in 1973 it had been raised and scraped at this time the barometer was salvaged. The tug had been renamed from the Howard Smith to the “Melbourne” after the Adelaide Steamship Co was taken over by Howard Smith& Co, who were heavily involved in towage, salvage and the stevedoring industries in 1961.The significance is that the item was on a vessel that was evolved in a serious collision in Port Philip Bay in 1972. It is linked with the activities of the Port at that time and helps to form a picture of what the maritime industries that operated from Port Melbourne were like and the activities that stevedore and towage companies underwent.Ship Barometer, in brass caseInscribed "Compensated" , "John Lilley & Gillie Ltd London & North Shields." and "Millibars".flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, maritime museum, shipwreck coast, flagstaff hill maritime village, great ocean road, barometer, ship's barometer, weather instrument, john lilley & gillie ltd, shipwreck artefact, the tigboat melbourne, north shields, howard smith, the melbourne, salvage

An hourglass or sandglass is an instrument for measuring a defined time and can be used perpetually by simply turning it over immediately the top bulb empties. The clear blown glass is shaped into two equal sized bulbs with a narrow passage in the centre and contains uniform sized sand or glass particles in the lower bulb. The width of the neck regulates the constant flow of the particles. The glass is held in a stand with top and bottom of equal shape and size. Hourglasses can measure an infinite variety of time by gauging the size of the particles, the shape and size of the bulbs and the size of the passage between the bulbs, thus measuring hours or minutes or even seconds. Generally an hourglass sits between discs of wood at the ends, which are joined by long wooden spindles between the ends and tightened by screw caps. The length of time can be adjusted by adding or removing sand particles. The use of the marine sandglass (or hourglass) has been recorded in the 14th century in European shipping. A one minute sandglass was used in conjunction with the ship’s log for ‘dead reckoning’, (see below) that is, for measuring the ship’s speed through the water. They were also used to regulate ringing the ship’s timetable; for example a 4 hour sandglass was used for the length of the sailors’ watch, and a half hour timer for taking of readings for the ship’s log; the ship’s bell would be rung every half hour. It was usually the role of the cabin boy to watch and turn the sandglasses over at the exact time of them emptying their upper chambers and to ring the ship’s bell. Hourglasses have been used historically for many hundreds of years. Some have been used for timing church sermons, in cooking, in industry and at sea. Even today they are used for measuring the cooking time of eggs and timing a player’s turn in games such as Boggle and Pictionary. The sandglasses at sea were gradually replaced in the late 1700’s to early 1800’s by the more accurate chronometers (marine clocks) when they became reliable instruments. DEAD RECKONING (or Deduced Reckoning) Dead reckoning is the term used to describe the method of calculating the ship’s position from its speed and direction, used in early maritime travel, mostly in European waters. Both the (1) speed and the (2) direction of travel were recorded on a Traverse Board at half-hourly intervals during a helmsman’s watch of 4 hours. The navigator would record the readings in his ship’s log, plot them on his navigational chart and give his updated course directions to the next helmsman on watch, along with the cleared Traverse Board. This was a very approximate, but none-the-less helpful, method of navigation. The wooden Traverse Board was a simple pegboard with a diagram of a compass with eight peg holes along the radius to each of the compass points, plus a grid with ascending half hours in the left column and increasing ship’s speed in knots in a row across the column headings, with a peg hole in each of the intersecting cells. A number of wooden pegs were attached to strings on the board. By placing one peg consecutively in the direction’s radius hole, starting from the centre, and the speed holes when the half hourly reading was taken, a picture of speed and direction for the whole 4 hour watch was created. (1) To measure the ship’s speed a one minute hourglass timer was usually used to measure the ship’s speed through the water and help to calculate its longitude. A rope, with knots at regular standard intervals and a weight such as a log at the end, would be thrown overboard at the stern of the ship. At the same time the hourglass would be turned over and a seaman would start counting the number of knots on the rope that passed freely through his hands as the ship travelled. When the timer ran out the counting would be stopped. A timer of one minute (one-sixtieth of an hour), knots spaced one-sixtieth of a nautical mile apart, and simple arithmetic easily gave the speed of the ship in nautical miles per hour ("knots"). This would be recorded every half hour. The speed could however be inaccurate to the travel being affected by ocean currents and wind. (2) To calculate the ship’s direction a compass sighting would be recorded each half hour.Marine hourglasses or sandglasses were used from around the 14th to 19th century during the time of sailing ships. This hourglass is representative of that era, which is during the time of the colonisation of Australia. Hourglass or sandglass; an instrument used to measure time. Two equal sized clear glass bulbs joined with a narrow passage between them, containing equal sized particles of sand grains in lower bulb. Glass sits in a brass collar at each end, in a frame comprising 3 decorative brass columns or posts, each attached top and bottom, using round screw-on feet, to round brass discs. Disc have Roman numerals for the numbers 1 - 12 pressed into their inner surfaces and hieroglyphics on the outer surfaces.

This mid-19th century scientific reference book, Introduction to Modern Geography, explains geography and astronomy using the globe of the world as a teaching aid. The inscription connects this book to the Bobinawarrah Public Library but research to date has found no further details about the library. The rural area was settled in 1859, but in 2016 its population was only 87. It is situated about 21 kilometres south of the City of Wangaratta, in Northeast Victoria. In 2024 the local community received a grant for preservation of its almost 100-year-old Bobinawarrah Memorial Hall which displays an honour board of the Pioneers of Bobinawarrah 1859-1959. The donor of the book lived in Warrnambool. ABOUT THE AUTHOR, James Thomson (1786-1849): - James Thomson was a British Irish mathematician. He became Professor of Mathematics at the University of Glasgow. He wrote many school textbooks and reference books, one of which was Introduction to Modern Geography, first published in Belfast in 1827, and revised and published in over 20 more editions. Thomson tutored two of his several children at home. His older son James Thomson (1822-1892) became an engineer and physicist. His younger son William Thomson (1824-1907) became Professor of Natural Philosophy from 1846-1899 at the University of Glasgow, and later the 1st Baron of Kelvin, famous for his designs of nautical instruments such as the navigational compass and sounding equipment used in the transatlantic installation of sea cable. William was part of the firm that became famous as Kelvin & Hughes Ltd., suppliers of radar and echo sounders to the Ministry of Transport and the Ministry of Defence. The name continued on as Kelvin & Hughes. James Thomson (1786-1849) was a renowned British Irish mathematician and Professor of Mathematics at the University of Glasgow. He was a respected author of many important school books and textbooks that were widely used to provide understanding of arithmetic and geography. Thomson encouraged practical education and held extra classes for young ladies to learn mathematics and geography, which were a novelty at that time. Many of his works were known and used worldwide. This work was published in many editions. It is now considered as culturally significant as a basis for knowledge about our civilisation and has been made publicly available in overseas countries, and republished and reproduced in a readable format, including its diagrams and maps.
