Flagstaff Hill Maritime Museum and VillageInstrument - Telescope, Mid-18th Century
... ...optical instrument...Telescopes are optical instruments that make distant objects appear larger and closer, thereby extending the range of what the human eye can observe. ...Telescopes are optical instruments that make distant objects appear larger and closer, thereby extending the range of what the human eye can observe. ...This Day or Night telescope, made by John Dollond, was designed for use in a range of lighting conditions, as its name suggests. Telescopes are optical instruments that make distant objects appear larger and closer, thereby extending the range of what the human eye can observe. The development of the telescope was gradual, shaped by a series of important advances in optical science. In 1608, the Dutch spectacle-maker Hans Lippershey discovered that when two lenses were held apart in a particular way, distant objects appeared closer. He applied for a patent for this invention, creating the first documented telescope. In 1668, Isaac Newton produced the first successful reflecting telescope, using a two-inch concave spherical mirror. This marked a major step forward, demonstrating that mirrors could overcome some of the limitations of lenses and greatly improve magnification. Further progress followed in the eighteenth century. In 1729, Chester Moor Hall developed the achromatic lens by combining two types of glass with different refractive properties. This reduced colour distortion and produced a sharper image, although some edge distortion remained. That same year, the Scottish instrument maker James Short developed parabolic and elliptical mirrors that were better suited to reflecting telescopes because they reduced optical distortion. Building on these advances, John Dollond improved the achromatic objective lens by placing a concave flint-glass lens between two convex crown-glass lenses, considerably enhancing image quality. Maker’s information. John Dollond (1707–1761), of London, was a maker of optical, scientific and astronomical instruments best known for developing the achromatic refracting telescope. He also introduced a practical heliometer, a telescope fitted with a divided lens that could be used to measure the Sun’s diameter and the angular distance between celestial bodies. The son of Huguenot refugees, Dollond first learned the family trade of silk weaving before turning his attention to optics and astronomy, in which he became highly skilled. In 1753, Dollond patented his improved lenses, the same year he had introduced the heliometer. In 1761, John Dollond was appointed as optician to George III and the Duke of York. He was also elected a Fellow of the Royal Society in May 1761, but died suddenly later that year in November. His share of the patent then passed to his eldest son, Peter. In later disputes between Peter Dollond and rival London opticians who challenged the patent, Peter consistently argued that, whatever earlier precedents may have existed, his father had independently developed a practical method for producing achromatic lenses through his command of Newtonian optics. By successfully defending the patent, the Dollond firm became one of the leading manufacturers of optical instruments. During the eighteenth and nineteenth centuries, the name ‘Dollond’ was at times used almost generically to mean ‘telescope,’ reflecting the firm’s reputation. Genuine Dollond telescopes were regarded as among the finest available. Peter Dollond (1731–1820) was the driving force behind the family business. He had founded a small optical business in 1750 on Vine Street, Halton Garden, with his father's guidance. The success of the business led to his father joining him in partnership in 1752. In 1959, J Dollond and Son opened a shop on The Strand, London. Dollonds appear to have produced both reflecting and refracting telescopes, and they possessed the technical skill to manufacture significant numbers of lenses largely free from chromatic aberration. In 1766, Peter went into partnership with his younger brother, John, and they traded under the name P and J Dollond. They supplied optical instruments for Captain Cook and George Hadley, an English lawyer and Meteorologist. In 1769, Captain Cook travelled with a Dollond telescope on the voyage to observe the Transit of Venus. Other notable customers included Thomas Jefferson and Admiral Lord Nelson. In 1781, Peter Dollond made bifocal spectacles. In 1804, young John Dollond passed away. The following year, Peter Dollond went into partnership with his nephew, George Huggins, and Huggins legally changed his surname to Dollond, and the firm remained P and J Dollond. In the early 20th century, the company sold film cameras. The firm remained in the hands of Dollond family members until 1927, when Dollond & Co. merged with James Aitchison & Co. to form Dollond & Aitchison, the well-known high street chain of opticians, which continued making and selling prescription spectacles. Now fully part of Boots Opticians, the company no longer manufactures instruments and operates exclusively as a retail business. The telescope in the collection is an excellent example of one of Dollond’s early library telescopes. Its association with one of eighteenth-century England’s leading innovators in optical development gives it considerable historical significance and makes it an important object within the collection. John Dollond’s experiments in optics advanced the understanding of the divergent properties of lenses and made a lasting contribution to the development of practical optical science. His work helped lay the foundation for major improvements in the design and performance of optical instruments. In his own time, Dollond was celebrated as the “Father of practical optics” and received widespread recognition for his achievements in the field. Dollond telescopes were associated with the renowned mariners, Captain James Cook and Admiral Lord Nelson Telescope: Dollond's Telescope, Day or Night model navigational instrument.

Flagstaff Hill Maritime Museum and VillageInstrument - Hydrometer, 1878 to 1930s
... The firm adverted hydrometers, as well as optical instruments, as early as August 13th, 1864, in The Age, Melbourne. ...The firm adverted hydrometers, as well as optical instruments, as early as August 13th, 1864, in The Age, Melbourne. ...This Sikes brass hydrometer was manufactured by the optical and scientific instrument makers Kasner & Moss of 17 Collins Street West, Melbourne, in the latter part of the nineteenth century. The firm adverted hydrometers, as well as optical instruments, as early as August 13th, 1864, in The Age, Melbourne. This hydrometer set was donated to Flagstaff Hill in 1979 by local wine and spirits merchants Lynch Bros of Fairy Street, Warrnambool. Giffen Russell had established the business in 1878, and Harry Lynch took it over in the 1930s, and after he passed away in 1953 Kevin Matthew Lynch became proprietor of K M Lynch Food and Liquor. The business closed in the 2010s. The hydrometer may date back to the establishment of the business in 1878, as Kasner & Moss were selling hydrometers in Melbourne from 1864. Hydrometers were used to measure the density, or relative density, of liquids from the late 1600s. In 1816 Bartholomew Sikes won the competition for the most useful accurate hydrometer. Hydrometers were commonly used by distillers, vintners, and brewers to establish accurate measures of alcohol concentration in their beverages. Following this manufacturing process, government inspectors and excise officers used them to check that the labelled indications of alcohol-proof were correct and that the right amounts of duty were being paid. This hydrometer and its fitted and hinged wooden container show signs of heavy and protracted use in a working environment. Although the instrument has some parts missing and has been recently repaired, the original quality of the inlaid box and the fine engraving on the instrument and the attachable weights, are indications of the hydrometer’s very real value when new. This Sikes hydrometer, bearing the maker's mark of “Kasner & Moss Melbourne” and the registered number “20373”, was presented to the purchasing public as a precision-made instrument designed for professional use. The Sikes hydrometer is of local significance because of its implied association with the alcohol trade in the southwest region of Victoria. It was donated by a family member of Lynch Bros, a local licensed outlet for wines and spirits in the period before the general relaxation of liquor licensing laws in the State of Victoria. It may have belonged to Griffin Russell who established the liquor store in 1878.Hydrometer; original Sikes brass hydrometer in a polished wooden case with an inlaid plaque on the lid. The brass float is a sphere with a thin flat upper stem and a short, lower stem with a bulb-shaped end. The upper stem is engraved scale on both sides with the numbers 1 to 10, and five divisions between each number. There are ten fixed pegs in the base to secure the thick brass horseshoe-shaped, numbered, various-sized weights (20, 30, 40, 80, 90); the free pegs would have originally stored another five weights (10, 50, 60, 70, and 100). The empty compartment in the box suggests another part in the initial set, probably a thermometer. The fitted, fabric-lined box has two brass closures and two brass hinges. The scientific instrument shows signs of heavy use and repairs. The Serial Number on the float matches the Serial Numbers on the weights. The plaque on the lid, the float and the weights have inscriptions. Made by Kasner & Moss, Melbourne. Plaque: “SIKES HYDROMETER / KASNER & MOSS / MELBOURNE” On float's lower stem: “SIKES 20373” On one thin edge of the float's scale, engraved in script “Kasner & Moss” and stamped “MELBOURNE”, and symbol“P” rotated 90 degrees.

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.

For a time in the eighteenth and nineteenth century the word 'Dollond' was almost a generic term for telescope rather like 'Hoover; is to vacuum cleaner. ...The discovery of the first telescope in 1608 can be attributed to Hans Lippershey of the Netherlands when he discovers that holding two lenses up some distance apart bring objects closer. He applies for a patent on his invention and this becomes the first documented creation of a telescope. Then in 1668, Newton produces the first successful reflecting telescope using a two-inch diameter concave spherical mirror. This opened the door to magnifying objects millions of times far beyond what could ever be obtained with a lens. It wasn’t until 1729 that Chester Moor Hall develops an achromatic lens (two pieces of glass with different indices of light refraction combined produce a lens that can focus colours to almost an exact point resulting in much sharper images but still with some distortion around the edges of the image. Then in 1729 Scottish instrument maker James Short invents the first parabolic and elliptic, distortion-less mirror ideal for reflecting telescopes. We now come to John Dollond who improves upon the achromatic objective lens by placing a concave flint glass lens between two convex crown glass lenses. This had the effect of improving the image considerably. Makers Information: John Dollond (1707-1761) London England he was a maker of optical and astronomical instruments who developed an achromatic (non-colour distorting) refracting telescope and practical heliometer. A telescope that used a divided lens to measure the Sun’s diameter and the angles between celestial bodies. The son of a Huguenot refugees Dollond learned the family trade of silk weaving. He became proficient in optics and astronomy and in 1752 his eldest son, Peter joined his father in an optical business, in 1753 he introduced the heliometer. In the same year, he also took out a patent on his new lenses. He was elected a fellow of the Royal Society in May 1761 but died suddenly in November and his share in the patent passed to his son Peter. In subsequent squabbles between Peter and the many London opticians who challenged his patent, Peter’s consistent position was that, whatever precedents there may have been to his achromatic lenses, his father had independently reached his practical technique on the basis of his theoretical command of Newtonian optics. As a result of maintaining his fathers patent, Dollond s became the leading manufacturer of optical instruments. For a time in the eighteenth and nineteenth century the word 'Dollond' was almost a generic term for telescope rather like 'Hoover; is to vacuum cleaner. Genuine Dollond telescopes were considered to be amongst the best. Peter Dollond (1731-1820) was the business brain behind the company which he founded in Vine Street, Spitalfields in 1750 and in 1752 moved the business to the Strand London. The Dollonds seem to have made both types of telescopes (reflecting and refracting), possessing the technology to produce significant numbers of lenses free of chromatic aberration for refracting telescopes. A Dollond telescope sailed with Captain Cook in 1769 on his voyage to observe the Transit of Venus. Thomas Jefferson and Admiral Lord Nelson were also customers of the Dollonds. Dollond & Co merged with Aitchison & Co in 1927 to form Dollond & Aitchison, the well-known high street chain of opticians, now fully part of Boots Opticians. They no longer manufacture but are exclusively a retail operation. John Dollond's experiments in optics and how different combinations of lenses refract light and colour gave a better understanding of the divergent properties of lenses. That went on to inform and pave the way for the improvement of our understanding of optics that are represented today. Dollond was referred to in his time as the "Father of practical optics" as a leader in his field he received many prestigious awards. The telescope in the collection is a good example of one of Dollonds early library telescopes and its connection with one of England's 18th-century pioneers in optical development is in itself a significant and an important item to have within the collection.

The firm had been tasked by the Ministry of Munitions to solve the problem of pilots dropping bombs by hand and as a result, they effectively created the first bomb rack. ...In August 1884, Alfred Hirst who had started his trade as a watch repairer and was described as a watchmaker extraordinaire established Hirst Brothers and Company, on Union Street in Oldham Manchester. He took his two stepbrothers into the business and the company was set up to produce timepieces and jewellery as well as importing “Limit company” Swiss watches and precision machine tools for the watch and clock trade. By 1902 Hirst Brothers. had become a limited company and was still growing, adding other businesses in Manchester in 1904 and at Birmingham in 1907. The quality of the clocks and watches was such that Alfred Hirst realised his greatest ambition in 1912 with a range of watches which carried the "Limit" trademark. These watch movements had originally been made in Switzerland and shipped to Hirst Bros. to be put into British made “Dennison” cases. This trade brought even more growth with additional sales offices opening in London and Glasgow. At the outbreak of the First World War in 1914 found them manufacturing aircraft parts including revolution counters and optical instruments. The firm had been tasked by the Ministry of Munitions to solve the problem of pilots dropping bombs by hand and as a result, they effectively created the first bomb rack. After the war, the company once again began to prosper and with the demand for their products increasing they looked to build a new purpose-built factory to manufacture their products. In 1917 they purchased a seven-acre field site at Tame Side Dobcross, the designing of the new factory was passed onto local architect AJ Howcroft. His brief for the design of the clockworks would have been prompted by Alfred Hirst who having visited modern factories in the United States was inspired by the latest factory designs providing as much daylight as possible during working hours. The factory was eventually completed in 1920, by the mid-1920s there were cheap clock imports from Germany and production turned to radio sets and other components as well as counter and gas meters for the "Parkinson and Cowan" company who was later to take over the business. In 1926 came the cotton crash and the District Bank who had loans with the company foreclosed on the Hirst loan. The company did survive and throughout the second World, War II were involved in munitions work at the factory as well as making instruments for various aircraft. In the 1950’s they were producing meters and high grade measuring equipment but by the 1970's the business had closed and the factory was demolished in the mid-1980 "s The item is a good example of the later use of an early mechanism “Fusee” that was originally invented around 1525 in Prague. This type of clock mechanism was replaced as watchmakers looked for mechanisms that could reduce the size of clocks and watches, it appears England was the only country to continue making clocks with a Fusee device until around 1900,s of which our clock is an example. The use of a Fusee movement eventually became obsolete in 1970,s. The item is significant for the collection as it is a clock with a movement that has long since been made obsolete. Fusee type gallery wall clock made by Tame Side with an 8-day mechanical fusee movement. The white enamel dial is a little crazed and some of the Roman Numeral numbers are fading due to over-cleaning. The movement has a hexagonal iron pendulum bob hooking onto a pendulum rod with a spring-wound anchor escapement.Only mark is stamped on the movement believed to be a production number "13490" and made in Tame Side.
