E. R. Watts and Son, makers of theodolites and other surveying instruments, of 123 Camberwell Road, London. The company was established in 1856 by Edwin Watts at twenty-three he had saved £100 from his earnings to start the business with his staff consisting of one boy and later Alexander Clarkson as an apprentice with the workshop a small room over a Bemondsey stable. Watts' first order was from Negretti and Zambra for a mining dial Alexander Clarkson In the early days the firm worked mainly on marine compasses. Edwin Watts would go down to the Docks to adjust the compasses once they had been installed on the ships. In May 1873 the business moved to larger premises a house with a garden. The workshop was also the home of Mr and Mrs Watts and their five sons and three daughters. By now there were fifteen to twenty men employed by the firm. The company were commissioned to supply the Theodolites and Levels for the construction to the Canadian Pacific Railway in 1881. Towards the end of the century, the firm began to make heliographs continuing to produce them for the government until just before the Second World War when by agreement assigned their manufacture to another firm. 1904 The first dividing engine was completed by George William Watts. It was so remarkable an instrument at the time and for years afterwards, In 1907 Arthur Ames went to Canada and started an organisation in Winnipeg in 1909 this became a separate company called E. R. Watts and Son Ltd. of Ottawa. This firm developed considerably and was eventually with the co-operation of three other instrument companies (Cambridge Instrument Co, Ross, and Negretti and Zambra), were reconstituted as ”Instruments Ltd” of Ottawa and Toronto. During the next ten years, the firm expanded greatly to include glass grinding, leather work, dividing and engraving, testing, adjusting and packing. This expansion was continued during the First World War when workshops were completed and the machinery installed and running within eleven weeks from the start of construction. During the war, a Sergeant Coles, among the rats, lice and mud of the trenches, fitted various bits of scrap into his cocoa tin and made the first Flash Spotter for plotting the positions of enemy guns. Coles was rushed home to the firm's factory where he and George William Watts designed a spotter not made out of a cocoa tin and as a result, the Watts Vertical Force Variometer was developed during WWI. Other Watts instruments made in the First World War included the Light Mountain Theodolites which were taken on Mt Everest expeditions. In 1919 ER Watts and Sons was incorporated as a limited company and in 1939 G. A. Whipple joined the Board of Directors. Shortly afterwards, Frank Charles Watts died having been Chairman of the firm for over 37 years and seen it through the First World War with all its expansions and difficulties. He was succeeded by his brother George William Watts with the vacant post of Managing Director being filled by G. A. Whipple. During the Second World War, the company expanded further and the number of employees rose to well over 1,300. In 1946 Watts acquired 78% of Adam Hilger and the microscope maker James Swift and Son Who were Manufacturers of Theodolites, Levels, Alidades, Meteorological Instruments, Variometers, and many other types of scientific instruments Then in 1948 the company amalgamated with Adam Hilger as Hilger and Watts which was then incorporated as a public company.Naval Rangefinder with a vertical wooden handle, and an arrangement of optical lenses.

A telescope is an optical instrument used to make distant objects appear nearer and larger, this item is small enough and designed to be portable enough to fit into a gentleman's pocket while out walking. This type, size and manufacture of the telescope was designed for general everyday use for bird watching and general observation of subjects while out walking. This item was not for marine use as its focal length is too short and could only observe subjects that were not too far away. Also, its size indicates telescopes of this type are pocket telescopes.This telescope is significant for its probable association with leisure activities of a person in the 19th century for leisure purposes such as bird watching, horse events and ship spotting.Three draw brass hand held telescope, folding.Noneflagstaff hill, warrnambool, shipwrecked-coast, flagstaff-hill, flagstaff-hill-maritime-museum, maritime-museum, shipwreck-coast, flagstaff-hill-maritime-village, telescope, folding telescope, navigational instrument, optical instrument, pocket telescope, leisure, brass telescope, hobby

Boyd designed the exhibition for the opening of the Australian Chancery in Washington DC held in June 1969. He designed six cylindrical clear acrylic display cases. One of these exhibits used an anamorphic optical illusion, using compressed images which had normal proportions when viewed through a lens of the half-cylindrical display cases. These bookends were designed as a small scale model for the Chancery exhibition. Placing the disc (item F158) underneath the adjacent two half-cylindrical bookends demonstrates how the bookends behave as a lens.Two half cylindrical acrylic prismsaustralian chancery, walsh st furnishings, robin boyd, ohm2022, ohm2022_3

Otto Schott, a chemist and glass engineer, had the vision of uniform production ie making glass items that would resemble one another. At the end of the eighteenth century, with most glass items still created by hand, the quality of output was still a guessing game. Schott was the first to render this an industrial certainty. 1884 Otto Schott, Ernst Abbe and Carl and Roderich Zeiss found the Schott & Associates Glass Technology Laboratory in Jena, Germany. Glastechnisches Laboratorium Schott & Gen was born. Production started in 1886. Original products included optical and thermometer glasses. The following year, a crucial discovery was made: borosilicate, a heat and chemically resistant glass. By it’s 25th year anniversary, the company had grown from an experimental glass factory into an internationally renowned manufacturer of optical and industrial glasses. Soon to be added was fiolax, tube-shaped glass used for vials, ampoules and syringes thus allowing the company to play a significant role in supplying Europe's nascent pharmaceutical industry.

This Dollond Day or Nigh telescope was designed to be used in any light conditions, as its name implies. Telescopes are optical instruments designed to make objects appear to be larger or closer. 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 is 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 Dollond's early library telescopes. Its connection with one of England's 18th century pioneers in optical development makes it a significant and an important item to have within the collection.Telescope: Dollond's Telescope, Day or Night model navigational instrument.

This is a set of five photographs of Multiplex mechanical stereoplotting equipment at the Army Survey Regiment, Fortuna Bendigo. c1950s. Multiplex equipment was imported from the UK in 1951 and introduced in the following year, to accelerate map production output covering CMF training areas at 1:25,000 map scale. Multiplex plotting was a productive advancement replacing the ‘Arundel’ method of graphical plotting planimetric detail that was expensive and slow, especially in timbered mountainous terrain. Air photos were made into small diapositives and mounted on racks in the exact position relative to when the aerial photos were taken. The technicians operated the Multiplex in a darkened room, with one photo projected with a green filter and the other through a red filter to form a 3D view of the overlapping photos. The 3D model projected onto a platen, which was a small platform that was raised up and down. The technician viewed the 3D image with special glasses fitted with red and green lenses. In the centre of the platen was a small pinhole that served as a floating mark, with a vertical pencil located exactly below the pinhole. This tracing table was moved to follow the topographic feature or contour line and draw it on the paper underneath. The technician raising or lowering the platform’s floating mark to match the height of the 3D terrain. It also replaced the slotted template method of mechanical adjustment of strips of aerial photography, however was restricted to each strip rather than between strips in the block. Although the Multiplex was phased out of production in 1968, it was used in the training of photogrammetry and aero-triangulation at the School of Military Survey located at Bonegilla, Victoria until the early 1990s. The history of the Multiplex is covered in more detail with additional historic photographs, in pages 50 to 51 of Valerie Lovejoy’s book 'Mapmakers of Fortuna – A history of the Army Survey Regiment’ ISBN: 0-646-42120-4.This is a set of five photographs of Multiplex mechanical stereoplotting equipment at the Army Survey Regiment, Fortuna, Bendigo. c1950s.

This 300 year old book deals with the theory of light and colour and with investigations of the colours of thin sheets, 'Newton's rings', and diffraction of light. Newton uses a wave theory of light and his corpuscular theory to explain his observations. Sir Isaac Newton (1643-1727) was a great figure in the history of optical science. His classic 'Opticks' was first published in English in 1704. This Latin edition of 1706 was published to satisfy a wider scientific audience in Europe. Newton was Lucasian Professor at Cambridge 1669-1693 and a fellow of Trinity College. He achieved fame as a creative mathematician and for his law of universal gravitation which explains planetary motions. He retired from research in 1693 to become a government official in London.This book is highly significant as a milestone in the study of optics. Although not a very rare book, only one other copy is listed by WorldCat in an Australian institution.Latin edition of Newton's 'Optics' translated by Samuel Clarke. This copy is bound in full calf leather of the period, 348 pages, with fold-out figures plus a 24 page appendix 'Enumeratio linearum tertii ordinis' and a 43 page appendix 'Tractus de quadratura curvarum'. It is in outstandingly good condition.Inscribed on the fly leaf in pencil is that this is the 2nd edition, the first in Latin, and that Newton gave Clarke 500 pounds for the translation.refraction, optics, newton, reflection

Not much is known about William Rothwell other than he is recorded as working as an optician and scientific instrument maker in Manchester at 277 Deansgate Street from 1780 until 1820. An entry in the “Complete History of the Trades of Manchester” published in 1822, in which the author describes Mr William Rothwell as an intelligent young man who is conversant in several languages. He went on to describe him as an philosophical instrument maker of optical and mathematical objects, specialising in spectacles, all sorts of surveyors instruments as well as eye glasses of all types. At present that is all that is known of William Rothwell other than his products were made to the highest standards of the time. Today his products are now actively sought by collectors and are currently fetching high prices at auction sales overseas. The telescope is a rare item even though not much is known about Rothwell's history his scientific instruments and optical items fetch high prices when they become available as collectors look for rare and well made items from the 18th and 19th centuries. Its completeness and good condition make it a very good addition to the collection at Flagstaff Hill.

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. On the opposite thin edge of the float: “N20.373”, “SIKES”, “I P % II O” (in ornate capitals).

An original Kerr-Grant Microbalance, modified by E.J.Hartung This balance was invented in the chemistry department by Bertram Dillon Steele, later first Professor of Chemistry at the University of Queensland 1910-1930, in collaboration with Professor Kerr Grant, Physics. The design was widely used by other chemists, including Masson's mentor, Professor Ramsay, working in London on newly discovered rare gases (especially Radon), and Professor Hartung in Melbourne, investigating the chemistry of the decomposition of silver salts in photographic processes. The principle of the microbalance was to measure the change in density of a gas by the shift in the balancing beam due to a change in pressure of the gas in the balance case. The quartz balancing beam was made by Bertram Steele who was particularly skilled in glassblowing. A quartz beam is the beam of the Aston microbalance based on the Steele/Grant instrument, and described by F.W. Aston, the inventor of the mass spectrometer. The bulb at one end of the beam contained a fixed amount of air, so that a change in the pressure of gas in the balance case changed the buoyancy of the beam, yielding a displacement in the beam which could be measured. By this means, differences in weight of about 10 nanogram could be measured, in amounts of up to 0.1 gram. Such differences are significant the increase in weight of a metal sample due to surface oxidation (Steele's interest) in the weight loss due to radioactive decay of Radium (Ramsay's work), and in the estimates of density change due to the isotopic distribution of Neon (Aston). Ernst Johannes Hartung was a chemist and astronomer. Educated at the University of Melbourne (BSc 1913, DSc 1919), he became lecturer in 1919, associate professor in 1924, and succeeded Rivett as chair of chemistry in 1928, remaining in this position until 1953. Hartung?s lecturing style surged with enthusiasm and he employed the use of screen projections to demonstrate chemical phenomena to large undergraduate classes. In 1935 he recorded Brownian movement in colloidal solutions on 35 mm cinefilm, which was later copied onto 16 mm film for the Eastman Kodak Co. World Science Library. This can be viewed in the Chemistry laboratory. He researched the photo decomposition of silver halides, and was awarded the David Syme Prize in 1926. He devoted time to the design and construction of a large, new chemistry building for the School of Chemistry (built 1938?1939). During World War II he was approached by Professor Thomas Laby, chairman of the Optical Munitions Panel, to chair the advisory committee on optical materials, to produce high quality optical glass in Australia. This was successful, with large-scale production achieved within ten months at a reasonable cost. Hartung served three terms as general President of the (Royal) Australian Chemical Institute, was an ex-officio councillor of the Council for Scientific and Industrial Research, and a Trustee of the Museum of Applied Science (now part of Museum Victoria).An original Kerr-Grant Microbalance, modified by E.J.

This model was used in lectures in the College from the mid 20th century. An ophthalmotrope is a mechanical model constructed to demonstrate the movements of the eyes and the actions of the various muscles which produce them. The first ophthalmotrope was made by Theodore Reute in 1845 and it was he who gave it the name 'ophthalmotrope'. Frans Donders (1818-1889) became interested in eye movements on reading Reute's work, and his subsequent studies were of physiological interest and also provided the basis for principles underlying the correction of squint. Because of the complexity of the actions and counter actions of the eye muscles, ophthalmologists of the 19th century sought a practical solution with the construction of mechanical models. Reute's second model of 1857 was more sophisticated. Its eyeballs contained lenses and the optical system could be moved backwards and forwards to simulate accommodation. Later ophthalmotropes are known by Landolt, Knapp and Snellen.This ophthalmotrope is the one that was used as a teaching aid in the College from the mid 20th century.Brass framed model to illustrate actions of extra-ocular muscles.
