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.

In 1984 the Commonwealth Government made available to Flagstaff Hill a collection of lead ingots and copper sheets recovered from the wreck-site of the LOCH ARD. They were presented to the Warrnambool City Council by the Hon. Tom Uren MHR, Minister for Territories and Local Government: “The Commonwealth recognises that shipwrecks like the LOCH ARD are our national heritage with important educational, recreational and tourist applications” (The Standard, Tuesday 8 May 1984). The LOCH ARD was wrecked in 1878. Unsuccessful salvage operations were then undertaken with the 90 ton paddle steamer NAPIER. In sudden bad weather this vessel too was sunk. The precise position of the LOCH ARD in the exposed and dangerous waters off Mutton Bird Island became lost to memory. The underwater location of the LOCH ARD was rediscovered in 1967 by a Warrnambool skindiver, Stan McPhee. In the two years following his find, the vessel was systematically pillaged by unauthorised salvagers. This led to the State and Federal Governments’ intervention in 1969. A roundup and seizure of recovered lead ingots and copper sheets was conducted by Commonwealth and Victorian Police. Offenders were charged and convicted. The “repossessed loot of the Tassie Boys” was placed into secure storage (Jack Loney, 1978, Wrecks & Reputations). The LOCH ARD manifest of cargo lists “Pig lead 50 tons, 994 pig & 37 rolls” and “Copper 33 plates, 53 bolts”. While the lead ingots have been subsequently described as “ballast”, the copper sheets are unlikely to have been associated with the ship’s normal complement in that way. Similar product lines in the cargo manifest are “Bar and rod iron 102 tons”, “Plate iron 3 tons” and “Zinc 12 tons”. These raw materials were used by colonial artisans such as blacksmiths and metal smelters to fashion, and repair, agricultural implements and industrial machinery. Copper was valued for its non-corrosive properties and its malleability, or ease of working. Both these qualities were useful, for example, in laying underground gas pipes that supplied lighting to residences, businesses and streetscapes in the mid-nineteenth century. As the nineteenth century progressed, the metal was also increasingly valued for its conductivity, with copper wiring linking colonial communities to each other, and the wider world, via the Telegraph system. The average weight of the copper sheets is 216 kilograms, calculated by "volume 0.1936m³ X Cu density 8930kgs/m³".The shipwreck of the Loch Ard is of significance for Victoria and is registered on the Victorian Heritage Register ( S 417). Flagstaff Hill has a varied collection of artefacts from Loch Ard and its collection is significant for being one of the largest accumulation of artefacts from this notable Victorian shipwreck. The collections object is to also give us a snapshot into history so we can interpret the story of this tragic event. The collection is also archaeologically significant as it represents aspects of Victoria's shipping history that allows us to interpret Victoria's social and historical themes of the time. The collections historically significance is that it is associated unfortunately with the worst and best-known shipwreck in Victoria's history. Large heavy sheets or panels of copper metal raised from the wreck of the LOCH ARD. The 10 sheets are of roughly similar dimensions and rectangular shape. They bear signs of prolonged submersion in seawater, with various degrees of limestone accretion, adhered marine growth, and green oxidisation. Three of the sheets are severely buckled, demonstrating the force of underwater explosives used in their salvage. One sheet appears cut or severed in a diagonal line downwards from its top left hand corner. One sheet has a 10cm X 10cm square cut out of its top right hand corner. All sheets are in sturdy, stable condition. No maker’s marks are visible.flagstaff hill, warrnambool, shipwrecked coast, flagstaff hill maritime museum, flagstaff hill maritime village, great ocean road, loch line, loch ard, captain gibbs, eva carmichael, tom pearce, glenample station, mutton bird island, loch ard gorge, sailing ship, copper sheet, manutacturing materials, metal imports, muntz
