Equipment - Stevenson Screen, Thomas Stevenson, ca. 1910
... meteorological forecast... Swiss Made meteorological device weather forecast weather ...Stevenson screens were first introduced in Australia in the 1880s and were widely installed by 1910. The screens have been used to shelter and protect thermometers and other meteorological instruments from rain and direct heat while the holes and double-louvre walls allowed air to flow around them. Sometimes other meteorological instruments were included in the weather stations, so there were different Stevenson Screen sizes. This authentic, original Stevenson screen was previously owned by the Australian Bureau of Meteorology and was used for many years for weather readings at the Cape Otway Light Station in southwest Victoria. The Lighthouse Keepers recorded the readings for minimum and maximum temperatures at 9 a.m. every day from January 1865 until April 1994. The equipment was sheltered in a Stevenson Screen from 1902 until April 15 1994, when the mercury thermometer was replaced by a platinum resistance probe within an Automatic Weather Station (AWS). This Stevenson screen is one of the two screens that then became redundant. The other Stevenson screen was kept to display to visitors. Lightkeepers were no longer required at the Cape Otway Light station either, due to the automated system. The meteorological instruments donated with the screen were used for measuring temperature and humidity. They are mounted on a metal bracket that fits across the screw holes on the screen’s internal frame. The glass-covered Relative Humidity (RH) sensor was made by the renowned precision instrument maker, Rotronic AG of Switzerland, which was founded in 1965. The firm made its first electronic temperature and humidity instrument in 1967. Meteorological records have been collected in Australia from the 1800s. The records were collated, published and used as a basis for weather forecasts. Many sectors, such as maritime and agriculture industries, have relied on these figures for making important decisions. The quality and placement of the meteorological instruments used to measure temperature and humidity are of utmost importance for accuracy. In early colonial times, there were no national standards for meteorological instruments that would allow for accurate figures and comparisons. Once the Bureau of Meteorology was established (around 1908 to 1910) the department installed Stevenson screens throughout Australia, many at lighthouses and light stations, and the measuring instruments were standardised. The Stevenson Screen was named after its inventor, Scottish Civil Engineer Thomas Stevenson (1818-1887) who was also the father of Robert Louis Stevenson, author. Stevenson developed the small thermometer screen around 1867. It had double-louvred walls around the sides and a top of two asbestos sheets with an air space between them and was thickly painted with a white coating that reflected the sun’s rays. This design was modified in 1884 by Edward Mawley of the Royal Meteorological Society. Standards were set for the locations of the screens and instruments, including their distance above ground level and the direction the door faced.Stevenson screens played a significant part in providing a standardised shelter for all meteorological instruments used by the Australian Bureau of Meteorology from about 1910 until 1994. The readings from the instruments gave the meteorological statistics on which weather forecasts throughout Australia were based. This Stevenson screen was used locally at Cape Otway, along the Great Ocean Road in southwest Victoria, so contributed towards our local forecasts and weather warnings.Stevenson screen, original, from the Australian Bureau of Meteorology’s weather station at the Cape Otway Lighthouse. The screen is a white wooden cupboard with a slanted cover raised above the top. The top has ten drilled ventilation holes, and the sides and door are made of downward-slanting double louvres. Two brass hinges join the door to the lower edge of the screen and a metal fitting at the top edge allows for a padlock closure. The screen is supported on four short legs, each with a hole drilled from side to side for fitting to a frame. Inside the screen are two wooden frames fitted with hooks and screws. The floor has three boards; one across the back and one across the front at the same level, and a board wider than the space between these boards is fitted higher, overlapping them slightly. Inside the screen, a pair of electronic instruments with short electric cables is mounted on a metal bracket with drilled holes in it. One of the instruments is a Relative Humidity (RH) probe. It is 26 cm long and is a glass tube with a filter on one end and an electrical connection on the other. It has inscriptions on its label, showing that was made by Rotronic AG, Switzerland. The other instrument is a Resistance Temperature Device (RTD) thermometer. It is 22.5 cm long and has a narrow metal probe joined to a hexagonal metal fitting. A brass plate on the front of the screen has impressed inscriptions. The screen is Serial Number 01/C0032, Catalogue Number 235862.Stamped into brass plate "CAT.

Barometer, 1858-1869
The barometer was either made or sold by T. Gaunt & Co. of Melbourne, a manufacturer, importer and retailer of a wide variety of goods including jewellery, clocks and watches, navigational and measuring instruments, dinnerware, glassware and ornaments. Thomas Gaunt photograph was included in an album of security identity portraits of members of the Victorian Court, Centennial International Exhibition, Melbourne, 1888. (See below for further details.) Admiral Fitzroy Pattern Barometer History: The stick mercury barometer was named after Admiral Robert Fitzroy of the Royal Navy (1805-1865) for his detailed instructions on how to interpret the weather, which were included with the instrument. Fitzroy was the captain of the HMS Beagle, also a weather forecaster to Charles Darwin and the second Governor of New Zealand. He developed many different types of barometers and was the first person to introduce the science of weather forecasting to the British Isles. A local manufacturer of scientific instruments, Thomas Gaunt, produced the barometer that was adapted for the southern hemisphere by Robert Ellery, the State Astronomer based at the Melbourne Observatory. In the original sale catalogue for Gaunt's, the item is described as "Gaunt's Fitzroy Barometers" and it was priced from 25/- to ₤9.9s. History of Thomas Gaunt: Thomas Gaunt established Melbourne's leading watchmaking, optical and jewellery business during the second half of the 19th century. Gaunt arrived in Melbourne in 1852, and by 1858 had established his own business at 14 Little Bourke Street. Around 1869 he moved to new premises in Bourke Street on the corner of Royal Arcade. Gaunt's shop quickly became a Melbourne institution. Gaunt proudly advertised that he was 'The only watch manufacturer in the Australian colonies'. While many watches and clocks may have had Gaunt's name on the dial, few would have been made locally. Gaunt did make some watches for exhibitions, and perhaps a few expensive watches for wealthy individuals. Gaunt's received a telegraph signal from Melbourne Observatory each day to correct his main clock and used this signal to rate and repair ship's chronometers and good quality watches. His main horological manufacturing was directed at turret clocks for town halls, churches and post offices. These tended to be specific commissions requiring individualised design and construction. He made the clock for the Melbourne Post Office lobby, to a design by Government Astronomer Robert Ellery, and won an award at the 1880-81 Melbourne International Exhibition for his turret clock for the Emerald Hill Town Hall. He became well known for his installation of a chronograph at Flemington Racecourse in 1876, which showed the time for the race, accurate to a quarter of a second. The firm also installed the clockwork and figures for Gog and Magog in the Royal Arcade. Thomas Gaunt also developed a department that focused on scientific instrumentation, making thermometers and barometers (from imported glass tubes), telescopes, surveying instruments and microscopes. Another department specialised in electroplating for trophies, awards and silverware, and the firm manufactured large amounts of ecclesiastical gold ware and silverware, for the church including St Patrick's Cathedral. There are no records that disclose the number of employees in the firm, but it was large enough for Gaunt to hold an annual picnic for the watchmakers and apprentices at Mordialloc from 1876; two years previously they had successfully lobbied Gaunt to win the eight hour day. Gaunt's workforce was reportedly very stable, with many workers remaining in the business for 15 to 30 years. Gaunt's wife Jane died on September 1894, aged 64. They had one son and six daughters, but only three daughters survived to adulthood. Two became nuns at the Abbotsford Convent and one daughter, Cecelia Mary Gaunt (died 28 July 1941), married William Stanislaus Spillane on 22 September 1886 and had a large family. Gaunt died at his home in Coburg, Victoria, leaving an estate valued at ₤41,453. The business continued as T. Gaunt & Co. after his death. The barometer is historically significant as an example of the work of Melbourne’s leading scientific instrument maker, Thomas Gaunt. The barometer has social significance as an example of the type of scientific equipment that Thomas Gaunt expanded his horology business into producing. Further social significance lies in the fact that Robert Ellery, the Government Astronomer who designed the local version of the barometer, had a direct connection with the Melbourne Athenaeum founded in 1839 as the Melbourne Mechanics' Institution. Its purpose was "the diffusion of literary, scientific and other useful information". There are also records of a T Gaunt as a subscription and committee member of this the Athenaeum organisation during the 1870s and 1880s which may be Thomas Gaunt, unfortunately still unverified.Stick mercury barometer known as the Admiral Fitzroy Barometer. It comprises an oblong wooden case with glass front panel, ornate pediment, barometer with bulb cistern (empty of fluid), cleaning brush with printed instructions for interpreting information given by the gauge affixed to left and right face of instrument. Includes a thermometer. The barometer appears to be intact. Adapted to the Southern Hemisphere. Special remarks by Admiral Fitzroy. Made by Thomas Gaunt, Melbourne.

Instrument - Barometer, 1867
Langlands Company History: Langlands foundry was Melbourne's first foundry and iron shipbuilder established in 1842, only 8 years after the founding of the Victorian colony by two Scottish immigrants, Robert Langlands and Thomas Fulton, who had formed a partnership before emigrating (1813–1859). The business was known as the 'Langlands Foundry Co'. Henry Langlands (1794-1863), left Scotland in 1846 with his wife Christian, née Thoms, and five surviving children to join his brother Robert. By the time he arrived in early January of 1847 the partnership of Robert Langlands and Fulton had dissolved as Fulton had gone off to establish his own works. It was at this time that the two brothers took over ownership of Langlands foundry. Several years later Robert retired and Henry became sole the proprietor. The foundry was originally located on Flinders Lane between King and Spencer streets. Their sole machine tool, when they commenced as a business, was a small slide rest lathe turned by foot. In about 1865 they moved to the south side of the Yarra River, to the Yarra bank near the Spencer Street Bridge and then in about 1886 they moved to Grant Street, South Melbourne. The works employed as many as 350 workers manufacturing a wide range of marine, mining, civil engineering, railway and general manufacturing components including engines and boilers. The foundry prospered despite high wages and the lack of raw materials. It became known for high-quality products that competed successfully with any imported articles. By the time Henry retired, the foundry was one of the largest employers in Victoria and was responsible for casting the first bell and lamp-posts in the colony. The business was carried on by his sons after Henry's death. The company was responsible for fabricating the boiler for the first railway locomotive to operate in Australia, built-in 1854 by Robertson, Martin & Smith for the Melbourne and Hobson's Bay Railway Company. Also in the 1860s, they commenced manufacture of cast iron pipes for the Board of Works, which was then laying the first reticulated water supply system in Melbourne. Langlands was well known for its gold mining equipment, being the first company in Victoria to take up the manufacture of mining machinery, and it played an important role in equipping Victoria's and Australia's first mineral boom in the 1850s and 1860s. Langlands Foundry was an incubator for several engineers including Herbert Austin (1866–1941) who worked as a fitter at Langlands and went on to work on the Wolesely Shearing machine. He also founded the Austin Motor Company in 1905. Around the 1890s Langlands Foundry Co. declined and was bought up by the Austral Otis Co. in about 1893. History for Grimoldi: John Baptist Grimoldi was born in London UK. His Father was Domeneck Grimoldi, who was born in Amsterdam with an Italian Father and Dutch mother. Domeneck was also a scientific instrument maker. John B Grimoldi had served his apprenticeship to his older brother Henry Grimoldi in Brooke Street, Holburn, London and had emigrated from England to Australia to start his own meteorological and scientific instrument makers business at 81 Queens St Melbourne. He operated his business in 1862 until 1883 when it was brought by William Samuel and Charles Frederick, also well known scientific instrument makers who had emigrated to Melbourne in 1875. John Grimoldi became successful and made a number of high quality measuring instruments for the Meteorological Observatory in Melbourne. The barometer was installed at Warrnambool's old jetty and then the Breakwater as part of the Victorian Government's insistence that barometers be placed at all major Victorian ports. This coastal barometer is representative of barometers that were installed through this government scheme that began in 1866. The collecting of meteorological data was an important aspect of the Melbourne Observatory's work from its inception. Just as astronomy had an important practical role to play in navigation, timekeeping and surveying, so the meteorological service provided up to date weather information and forecasts that were essential for shipping and agriculture. As a result, instruments made by the early instrument makers of Australia was of significant importance to the development and safe trading of companies operating during the Victorian colonies early days. The provenance of this artefact is well documented and demonstrates, in particular, the importance of the barometer to the local fishermen and mariners of Warrnambool. This barometer is historically significant for its association with Langlands’ Foundry which pioneered technology in the developing colony by establishing the first ironworks in Melbourne founded in 1842. Also, it is significant for its connection to John B Grimoldi who made the barometer and thermometer housed in the cast iron case. Grimoldi, a successful meteorological and scientific instrument maker, arrived in the colony from England and established his business in 1862 becoming an instrument maker to the Melbourne Observatory. Additional significance is its completeness and for its rarity, as it is believed to be one of only two extant barometers of this type and in 1986 it was moved to Flagstaff Hill Maritime Village as part of its museum collection. Coast Barometer No. 8 is a tall, red painted cast iron pillar containing a vertical combined barometer and thermometer. Half way down in the cast iron framed glass door is a keyhole. Inside is a wooden case containing a mercury barometer at the top with a thermometer attached underneath, each with a separate glass window and a silver coloured metal backing plate. Just below the barometer, on the right-hand side, is a brass disc with a hole for a gauge key in the centre. The barometer has a silvered tin backing plate with a scale, in inches, of "27 to 31" on the right side and includes a Vernier with finer markings, which is set by turning the gauge key. The thermometer has a silvered tin backing plate with a scale on the left side of "30 to 140". Each of the scales has markings showing the units between the numbers.Inscription at the top front of the pillar reads "COAST BAROMETER" Inscribed on the bottom of the pillar is "No 8". and "LANGLANDS BROS & CO ENGINEERS MELBOURNE " The barometer backing plate is inscribed "COAST BAROMETER NO. 8, VICTORIA" and printed on the left of the scale, has "J GRIMOLDI" on the top and left of the scale, inscribed "Maker, MELBOURNE". There is an inscription on the bottom right-hand side of the thermometer scale, just above the 30 mark "FREEZING" Etched into the timber inside the case are the Roman numerals "VIII" (the number 8)flagstaff hill, warrnambool, maritime village, maritime museum, flagstaff hill maritime museum & village, shipwreck coast, great ocean road, warrnambool breakwater, coast barometer, coastal barometer, barometer, weather warning, ports and harbours, fishery barometer, sea coast barometer, austral otis co, coast barometer no. 8, henry grimoldi, henry langlands, john baptist grimoldi, langlands foundry co, meteorological instrument maker, robert langlands, scientific instrument maker, thermometer, thomas fulton -

Instrument - Chronometer or Marine Clock, ca. 1935 to 1975
This chronometer was made around 1936 and has been on display at Flagstaff Hill for over 40 years as part of the exhibit of the ‘Reginald M’, an Australian-built, 19ss, coastal trader vessel. A chronometer is an accurate mechanical instrument used for measuring time. It is constructed carefully to remain stable even under the changing conditions of seafaring life such as temperature, humidity and air pressure. The Master or Navigator of a ship could use the chronometer and the positions of celestial bodies to calculate the ship’s latitude at sea. In 1905 the business Chronometerwerke GmbH was formed in Frankfurt, Germany, to supply the country with high-quality mechanical chronometers and ship clocks for their maritime trade, making the country independent of other international suppliers such as those in England. In 1938 the firm was renamed Wempe Chronometerwerke. The business continues today. Its products now include its well-known chronometers, battery-powered ship clocks, ship’s bell clocks, barometers, barographs, thermometers, hygrometers, comfort meters to measure temperature and humidity, and wristwatches. The company also performs chronometer testing facilities for the State’s Weights and Measures office. The article written by Givi in July 2022 “The Basics of Marine Meteorology – a Guide for Seafarers” refers to the weather’s signs and patterns being repeated over and over, and the recording of these observations helps forecasters predict changes in the weather. The chronometer is an example of a mechanical navigational marine instrument in use in the early to the mid-20th century. The maker is significant as part of a German government initiative to be self-sufficient in the production of good quality marine technology. This chronometer is significant as part of the exhibit, the Australian-built vessel, 1922 coastal trader ‘Reginald M’, listed on the Australian Register of Historic Vessels and on display for over 40 years.Marine chronometer or marine clock, brass case, glass cover, Roman numerals, 24-hour numbers beside them.

Journal - Record Book, Meteorological Observations, 1947-1948
This bundel of twenty pages of meteorological observations covers the period between March 1947 and April 1948 but there are some gaps. The bundle includes handwritten records on pre-printed forms from the Commonwealth Government and brief records on plain paper. There are calculations for monthly totals of information such as rainfall, and there are some comparisons between the years. One of the forms has handwriting in three directions, which is quite unusual. Readings were recorded daily for barometer, temperature and wind. There was also a section for comments on Exceptional Phenomena such as storms and fog. . It was one of the many duties of the Lighthouse Keeper or his Assistant to keep these records and make the mathematical calculations required by the Government. Information gathered from Lighthouse Keepers' letters tells of the large amount of time taken for this detailed work and the lack of payment made for such a responsibility. The quite detailed record for May, June and July 1947 were signed by C Carrington, Harbour Master for Warrnambool. Captain Carrington was responsible to the Harborus Board. He was responsibilite for the fortnightly training of the Warrnambool Lifeboat Crew on the practice of lifesaving and using the Rocket Rescue equipment. These Meteorological Observations are an important accurate record of the local weather since the late 1899s. They are part of Flagstaff Hill's Meteorological Observations collection of over seventy record books dating from the late 19th century. The collected information gives a picture of the weather patterns for the months and seasons, which then allows for warnings of events out of the normal or extreme, such as forecasting floods or droughts.Meteorological Observations for Warrnambool March 1947 to May 1948. A bundle of unbound sheets of paper joined at the top left corner with a metal fastener. The pages are ordered from most recent on top to the oldest on bottom. The older records are on pre-printed forms and include many handwritten details. The more recent records are handwritten on plain paper. There is a line for each day of the month and lines for calculations at the bottom of the page. The handwritten Information includes readings for Barometer, Temperature, Wind and Rain.
