It took eight years, five major contractors and the relentless labour of 432 construction workers to build Tower Bridge. Two massive piers were sunk into the river bed to support the construction and over 11,000 tons of steel provided the framework for the Towers and Walkways. This framework was clad in Cornish granite and Portland stone to protect the underlying steelwork and to give the Bridge a more pleasing appearance.(http://www.towerbridge.org.uk/bridge-history/)tower bridge, london

Hollis Brothers were first recorded trading from 11 Weaman Row in 1840 but appear to have started trading a little earlier. The firm later became Isaac Hollis & Sons and claimed establishment from 1814. Richard & William Hollis were recorded trading in Bath Street Birmingham from 1814 to 1818 so it may be that the Hollis brothers were descended from them. The brothers were Isaac Hollis (b.1815) and Frederick Hollis (birth date unknown), but Frederick died 20 December 1839. Isaac was recorded in the 1841 census living in Weaman Row. He was a 25-year-old gun and pistol maker, married to Emma 1821. They had two children, Isaac (1837), and Henry (1839). After Frederick died, Isaac carried on trading under the name of Hollis Brothers until 1845 when he re-named the business Hollis Brothers & Co who traded up to 1848. In 1844 Isaac entered into a short term partnership with William Tranter at 10 & 11 Weaman Row, presumably to complete a particular contract or supply certain parts. This partnership lasted until 1849. In 1848 Isaac took in Isaac Brentnall Sheath as a partner, and the firm of Hollis & Sheath was established, expanding into 10 Weaman Row. Hollis & Sheath were licenced makers of percussion breech-loading guns. In 1861 the firm changed its name to Isaac Hollis & Sons on the departure of Isaac Brentnall Sheath. Isaac Sheath died in July 1875. By about 1870 Isaac Hollis and Henry Hollis had taken over the day to day running of the business. Isaac Hollis was responsible for the overall management and the marketing of the firm's products. Henry was responsible for manufacturing. The firm became volume producers of inexpensive trade guns and sporting guns for the South African and the British colonies. In 1870 the firm opened a shop at 44a Cannon Street in London; in 1871 this moved to 83 Cheapside. Isaac Hollis Jnr died October 1875 in Birmingham aged 37. He was never married and in 1876/1877 Henry registered a limited liability company, Isaac Hollis & Sons Ltd, but by 1879 they were again trading as Isaac Hollis & Sons. From 1879 the London shop was at 6 Great Winchester Street. From 1932 to 1933 the London business traded as Hollis, Bentley & Playfair Hollis, Bentley & Playfair finally closed in Birmingham in 1953. This gun is a typical example of the type of firearm issued to the colony's military in 1861. Specifically made by Isaac Hollis and Sons for the military market of the time and sold through contractors Hebbert & Sons, military suppliers, in London. The gun was probably issued from the Hythe Armory to British troops (a training facility) or police prior to coming to Tasmania Australia around 1861.Gun; Percussion Carbine, .577 Cal.

Siebe Gorman & Company Ltd was a British company that developed diving equipment and breathing equipment and worked on commercial diving and marine salvage projects. The company advertised itself as 'Submarine Engineers'. It was founded by Augustus Siebe, a German-born British engineer chiefly known for his contributions to diving equipment. Siebe Gorman traded as an engineering firm for over 180 years from 1819 to 1999. The early success of the business was due to its founder, the Prussian immigrant Christian 'Augustus' Siebe (1788-1872). For business reasons, he applied for and was granted British citizenship in 1856. He was a gifted engineer who was able to translate theoretical problems into practical, working products. During the industrial Victorian period, the business traded as 'A. Siebe' at 145 High Street Holborn London, but in 1828 new premises were acquired at 5 Denmark Street, Soho. The family firm produced a wide range of manufactured goods including paper-making machinery, measuring machinery, water pumps, refrigeration equipment, and diving apparatus. Augustus Siebe specialised in submarine engineering early on and the company gained a reputation for the manufacture of safe, reliable diving apparatus. Augustus Siebe is best remembered for the development and manufacture of the ‘closed’ Diving Dress based on the ideas of Charles and John Deane, George Edwards, and Charles Pasley. Apart from some small modifications to valves and diver communications, the basic 12 bolt ‘closed’ diving dress remained relatively unchanged after the 1870s. Later company successes were also based on innovation, with new products that could be successfully developed and manufactured to high standards. This was largely attributed to the inventive nature, foresight, engineering, and entrepreneurial skills of Robert Henry Davis (1870-1965). In 1882, RH Davis joined the company of 'Siebe & Gorman' as a young 11-year-old office boy and he was to remain with the company until he died in 1965. Augustus Siebe retired in 1869 and handed over the company to a new partnership of Henry H. Siebe (1830-1885) and William A. O'Gorman (1834-1904). The new firm traded as 'Siebe & Gorman' (1870-1879) from premises in and around Mason Street, Westminster Bridge Road, Lambeth, London. The two partners soon recognised the potential of R.H. Davis and in 1894, aged 24, he became General Manager of Siebe & Gorman. Davis increasingly ran the company until the surviving partner (W.A. Gorman) died in 1904. The firm was disposed of to the Vickers (armaments) family and a new company 'Siebe Gorman & Co. Ltd.' (1905-1998) was formed. Under the chairmanship of Albert Vickers, R.H. Davis was kept on as Managing Director, and the company forged ahead. However, after WW1, the Great Depression caused manufacturing output and share prices to slump. In 1924 Robert Davis made a deal with the Vickers Board and acquired control of the company through majority shares. Under his leadership, the Siebe Gorman Company flourished and within time, four of his sons also joined the firm. The company gained a worldwide reputation for the manufacture of diving apparatus, decompression and observation chambers, and safety breathing apparatus of all types for use on the land, in the air, and under the sea (including mine rescue, tunneling, aircraft, diving, submarine escape and in other hazardous environments). Close research and development links with the MOD (especially the Admiralty), also provided a lucrative outlet for the company products. In 1932, Robert Davis was knighted by King George V, principally for his invention of the ‘Davis Submerged Escape Apparatus’ (D.S.E.A.). Siebe Gorman essentially remained a family firm from the beginning (under A.Siebe) until it became a public company for the first time in 1952. However, following WW2, British manufacturing stagnated through stifled investment and post-war austerity, and there was little innovation. Siebe Gorman's fortunes began to decline as an aging Sir Robert Davis failed to invest, or change the company's business and management practices. In 1959, Siebe Gorman was acquired by the “Fairy Group” and the ailing Sir Robert was made Life President. Consequently, nothing changed and the slow decline continued until Sir Robert's death in March 1965. Around 1960, Siebe Gorman acquired the diving apparatus manufacturer C E Heinke, and for a brief period, it manufactured some diving equipment under the combined name of Siebe Heinke. Around 1964, Mr E. 'Barry' Stephens was appointed as the new Managing Director to modernise Siebe Gorman. Changes were made, including a move to a new factory in Wales in 1975. The new company concentrated on fire-fighting breathing apparatus and escape equipment, and the move coincided with the loss of many of the older, traditional craft skills. Between 1985 and 1998, Siebe expanded through acquisitions, and several other companies were acquired. The Siebe Gorman (diving apparatus) company has therefore traded as A. Siebe (1819-1870); Siebe & Gorman (1870-1879); Siebe Gorman & Co (1880-1904); Siebe Gorman & Co. Ltd (1905-1998). (For information regards the diving helmet & Frank King see Notes Section at the end of this document)The items are very significant as a snapshot into marine history and the development of diving equipment generally especially that used for salvage operations before and during WW2. The company that made the equipment was a leading inventor,developer and innovator of marine equipment with its early helmets and other items eagerly sought after today for collections around the world. The items in the Flagstaff Hill collection give us an insight as to how divers operated and the dangers they faced doing a very necessary and dangerous job.

"Freight forwarding" is the arranging of the shipping of goods from their point of origin to their final destination. Freight Forwarders worked as an intermediary between companies that needed to ship products and the shipping and transportation firms that could ensure delivery. A key element of "freight forwarding" was the advice and professional handling of documentation and customs requirements provided. Early "freight forwarders" tended to be innkeepers who forwarded on the luggage of their hotel guests. One of the first "freight forwarding" companies was established by Thomas Meadows in 1836 which made it one of the earliest freight companies in Europe. More reliable rail and steamships were beginning to be used to transport goods and this created a demand for the new "freight forwarding" industry. The combination of railroads and steamships became very important in the late 19th and early 20th century. International shipments became common and freight forwarding that could handle their complexity became an integral part of the manufacturing and shipping landscape. Thomas Meadows & Company Ltd moved to offices in Milk Street, London in 1854 (where they remained until 1969 when they moved out of the city to Leytonstone) and continued in the freight business until 1987 when the company was acquired by Rockwell International Freight. The growth of Thomas Meadows & Company Ltd coincided with the growth and development of the colony of Victoria with an increasing need for the transporting of large numbers of people as well as important goods required by the growing colony - furniture, spirits, food, clothing, agricultural implements, household items etc. In the late 1840's only two or three overseas ships a month visited Melbourne but by late 1852 (after gold was discovered) more than a dozen ships arrived each week. By 1939, Thomas Meadows & Co. Ltd. had offices in Canada, U.S.A., New Zealand, France, Belgium and in Flinders Street Melbourne. This poster was sold by "Smarts Authorised Newsagency" in 1988 in Warrnambool - a business that had been owned by Neil and Shirley Smart at 168 Timor Street, Warrnambool since 1976. Previously it had been "Reed's Newsagency and Book Shop" (a local business established by William Reed circa 1912 and known as "William Reed Bookseller and Stationer"). The original owners, Reed's Newsagency and Bookshop were operating the shop in 1939 which suggests the poster may have been on display (for the information of their customers) in their shop at that time. This poster is significant through its association with Thomas Meadows and Co. Ltd. who is considered to be the founder of the "freight forwarding" industry in the early 19th century. It is an example of advertising used by shipping agents in the mid-19th to early 20th centuries. Its information includes the addresses of the firm's different offices in the U.K. and abroad, ships, shipping lines and ports used and the timetable the vessels were likely to follow. It is also significant through its association with a well known and long standing local Warrnambool business.A 1939 Timetable of "Australian Sailings" produced by the shipping agents Thomas Meadows and Co Ltd. It lists all their ships (plus dates and ports) sailing from the UK to Australia as well as the addresses of their offices in other cities in the U.K., Canada, U.S.A., Australia, New Zealand, France and Belgium. It has three vertical columns depicting (from left to right) January to June sailings, a simple 1939 calendar and their July to December 1939 sailings.

This book, The Australian Psalter, was part of the furniture and furnishings from the St Nicholas Church, Williamstown. It was used in the worship service there until the church closed. The items from the church and the Missions to Seamen were then donated to Flagstaff Hill and are known as the St Nicholas Seamen's Church Collection. The publisher, Novello & Co., of London, published the book in 1903. One reference noted that "It was printed in response to a desire expressed by the Diocesan Synod of Sydney in 1903" (National Library of Australia Catalogue). THE MISSIONS TO SEAMEN (Brief History: for more, see our Reg. No. 611, Set of Pews) The Missions to Seamen was an Anglican charity that served seafarers of the world since 1856 in Great Britain. It symbol is a Flying Angel, inspired by a Bible verse. Today there are centres in over 200 ports worldwide where seamen of all backgrounds are offered a warm welcome and provided with a wide range of facilities. In Victoria, the organisation began in Williamstown in 1857 as a Sailors’ Church, also known as ‘Bethel’ or the ‘Floating Church’ in an old hulk floating in Hobson’s Bay, Port of Melbourne. It soon became part of the Missions to Seamen, Victoria. In the year 2000 the organisation, now named Mission to Seafarers, still operated locally in Melbourne, Portland, Geelong and Hastings. The Ladies’ Harbour Lights Guild was formed in 1906 to support the Missions to Seamen in Melbourne and other centres such as Williamstown. Two of the most significant ladies of the Guild were founder Ethel Augusta Godfrey and foundation member Alice Sibthorpe Tracy (who established a branch of the Guild in Warrnambool in 1920). The Guild continued its work until the 1960s. In 1943 a former Williamstown bank was purchased for the Missions to Seaman Club. The chapel was named St Nicholas’ Seamen’s Church and was supported by the Ladies’ Harbour Lights Guild, the Williamstown Lightkeepers’ Auxiliary and the League of Soldiers’ and Sailors’ Friends. It ceased operation in 1966. A Missions to Seamen Chapel and Recreation Room was a significant feature of ports during the late 1800s and into the 1900s. It seemed appropriate for Flagstaff Hill to include such a representation within the new Maritime Village, so the Melbourne Board of Management of Missions to Seamen Victoria gave its permission on 21st May 1979 for the entire furnishings of the Williamstown chapel to be transferred to Flagstaff Hill. The St Nicholas Seamen’s Church was officially opened on October 11, 1981, and closely resembles the Williamstown chapel. The Australian Psalter is historically significant for its connection to the Ladies Lightkeepers’ Auxiliary, an organisation of women, formed to support seafarers. It is an important part to the worship services held at the St Nicholas Seamen's Church in Williamstown. This book is significant historically for its origin in the St Nicholas Mission to Seamen's Church in Williamstown, established in 1857 to cater for the physical, social, and spiritual needs of seafarers. It originated in Bristol, England when a Seamen's Mission was formed in 1837. The connection of this book to the Mission to Seamen and to the Ladies Lightkeepers’ Auxiliary highlights the strong community awareness of the life of people at sea, their dangers and hardships, and their need for physical, financial, spiritual and moral support. The Book, The Australian Psalter, was published by Novello and Company, London. Blue fabric-covered book with gold-embossed text, two bands of seven stars, and an emblem of the sun surrounded by stars on the front cover. The book contains the Psalms of David and the Canticles and Proper Psalms Pointed for Chanting. It is stamped with the library stamp Missions and Seamen, Melbourne. The book is now part of the St Nicholas Seamen's Church Collection.Embossed text: "THE / AUSTRALIAN / PSALTER" Emblem: [six stars] around [sun] Stamp: "From the Missions to Seamen Melbourne"flagstaff hill maritime museum and village, flagstaff hill, warrnambool, maritime museum, maritime village, shipwreck coast, great ocean road, religion, religious service, st nicholas seamen’s church, williamstown, missions to seamen victoria, psalter, hymn book, worship service, songs of worship, novello & co. london, worship music, the australian psalter

Frank Wright was a renown resident of Smeaton, where he was born on 2 August 1901. He lived at Laura Villa, and attended Smeaton State School. His father William was a gold miner and his mother's name was Sarah. Their family won many singing and instrumental awards. Frank was tutored by Percy Code and was awarded a gold medal for the highest marks in the ALCM examinations in the British Colonies at the age of seventeen years. He became the Australian Open Cornet Champion by the age of eighteen. A year later, Frank conducted the City of Ballarat Band, and later the Ballarat Soldiers’ Memorial Band. He formed the Frank Wright Frisco Band and Frank Wright and his Coliseum Orchestra. These bands won many South Street awards, and Frank as conductor won many awards in the Australian Band Championship contest. In 1933 Frank Wright sailed to England to conduct the famous St Hilda’s Band and was later appointed Musical Director of the London County Council, where he organized many amazing concerts in parks, in and around the London district. He was made Professor of Brass and Military Band Scoring and conducted at the Guildhall of Music and Drama. Frank was often invited to adjudicate Brass Band Championships around Europe, in Australia, including South Street and in New Zealand. The Frank Wright Medal at the Royal South Street competition is awarded to an individual recognized as making an outstanding contribution to brass music in Australia.Single page of think paper with black printing, containing the information about the concert held in 1953.

Copies of photos of the No 1 Australian Auxiliary Hospital set up in the ground of Harefield Park during the first World War. They were wooden huts. Also the graves of the deceased soldiers in the Australian Military Cemetery in 1919 in Harefield's St Mary's churchyard. Plus two photos of the Mansion at Harefield one in 1917 and one from 1927. Harefield Park was owned by Australian couple, Letitia Billyard-Leake (born Letitia Leake) and her husband Charles Billyard and their 4 children. The family donated their property, Harefield Park, to the Australian Government for use as an Australian-run hospital. The family moved off the property and lived nearby to help run the hospital. Letitia and her daughter, also named Letitia, ran the canteen while Charles Billyard organised activities and was a hospital board member. (from research from Carol Grbich and John Berger). During World War 1 the Australian Auxiliary Hospital No.1 was stationed at Harefield Park in Harefield, UxBridge, Middlesex UK. 111 Australian soldiers and one nurse from the hospital are buried at St Mary's Church, Harefield. This became an Australian Military Cemetery with individual headstones and an obelisk and arch. The headstones which are of a scroll design unique amongst Commonwealth War Graves Commission cemeteries were chosen by the staff and patients at the hospital. The arch was erected by the CWGC. Anzac Day services are held there and the local school became involved with the headmaster, Mr Jefferies, bringing the school children to lay flowers on every grave and attend the service on Anzac Day. This started in 1921 and has continued until at least 2021. One school child who attended was Mr Alf Young, he made contact with Legacy in the 1990s and sent photos of the Anzac Day Services and the cemetery. Legacy responded by sending Australian flags for the school children and also Legatee John Cohen met with Mr Young when in London. Melbourne Legacy staff member Susie Howard also visited Mr Young and the cemetery in 1995. Mr Young provided historical photos and information of the area to Legacy. He was featured in the widows' newsletter The Answer many times and his death was announced in The Answer in April 1997, he was 85. Many of the photos he provided were labelled as coming from Mr R G Neil, Photographic historian from Harefield. He holds copyright over those photos.A record that Legacy helped support remembrance of Anzac Day and World War 1 soldiers buried in the UK.Black and white photos x 4 of the Harefield Hospital and area from 1917 to 1927.02067.1 Printed on front 'Australian Auxiliary Hospital, Harefield No 1. 1914-1918'.

This pH meter was made in 1946 by Cambridge Scientific Instrument Co. Ltd. in London. The company was founded in 1881 and the owner eventually became Horace Darwin, the youngest son of the famous scientist Charles Darwin. It is a portable version that can be used on-site in many different situations. A similar instrument was used by the Chemistry Department of what is now the University of Cambridge. The science of pH measurement began in the 1910s and was further developed in 1926. The pH meter is an electronic scientific instrument used to determine the pH measurements of a solution accurately; the amount of acid and alkaline in it This measurement can have many other applications helping to maintain the appropriate balance for a particular result. For example, it can measure the pH of pharmaceutical medications, soil, swimming pool water and hair shampoos. This Cambridge portable electronic pH instrument was made in 1946 by a company specialising in scientific instruments. It is an early example of much smaller devices used today in many different fields including medicine, and the preservation and conservation of shipwreck artefacts. Flagstaff Hill Maritime Museum and Village's Curator uses a pH meter today in the conservation process of a historic cannon that was recovered from the 1839 wreck of the vessel 'Children'.Scientific instrument, electric Cambridge Portable pH Meter in a polished wooden box with compartments, fold-out doors, and leather carry handle. Includes blue covered Instruction manual with a 'Certificate of Test' inside, and chemicals. Electrodes mounted in compartment. The lid is separate from the base, attached by pins and hinges.
