This compressor was part of the E.G. Ward Collection. It is connected to the diving suit and boots, also in our collection. 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's 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 in 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, tunnelling, 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's 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 ageing 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 firefighting 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).The diving compressor, along with associated equipment in the Flagstaff Hill collection, represents a highly significant snapshot of marine history. These items are particularly important in understanding the evolution of diving equipment, with a special focus on their use in salvage operations before and throughout the Second World War. Manufactured by a company renowned for its inventions, development, and innovation in marine engineering, the equipment demonstrates the progression of technology in deep-sea diving. Early helmets and related items produced by this company remain highly sought after by collectors worldwide, highlighting their historical and technological value. The presence of these items within the Flagstaff Hill Maritime Museum allows for a unique insight into the working conditions and methods employed by divers. It also illustrates the considerable dangers they faced while performing such essential and hazardous work, underscoring the critical role played by these professionals in maritime history.A single cylinder divers' pump by Siebe Gorman & Co Ltd, London, eccentric hand cranked in brass, brass-mounted mahogany case with instructions to the underside of the lid, brass-covered pressure gauge and air outlet, brass maker's plaque to the front, water inlet and outlet to the rear, green-painted lifting rings.

Diver's Submarine Electric Torches were first developed to give illumination for close examination work. They have to be self-contained, the older ones are powered by an accumulator type battery which could be recharged. Some models were fitted with a switch to turn the light off saving on the battery power. The lens is of a convex type and magnifies the light. Sometimes there was a protective grill across the glass or prongs to protect the glass from an impact. When fully charged the battery would last about seven hours. Torches are made from non-ferrous metal so as not to corrode in their watery environment. Siebe Gorman & Co Ltd has been producing hand-held, battery-powered, submarine electric torches for divers and the Ministry of Defence (MOD) since the 1920s. In 1961, the famous diving manufacturer C.E. Heinke merged with Siebe Gorman, and for a short while, torches were made with the combined 'Siebe Heinke' inscription. However, this linked inscription was later dropped, with a return to the Siebe Gorman name tag. Date of manufacture for these torches can be determined by their Admiralty Pattern (AP) number that was used to identify a particular item and were for naval stores use. Before NATO stock coding became more widely used, earlier MOD torches often have a simple four-digit group of AP numbers such as AP4456 or AP4458. In 1975 Siebe Gorman moved from their Neptune Works at Chessington in Surrey to a new location at Cwmbran in Wales and by this time their manufacture of diving equipment had declined.

This mask set is part of the North East Region Water Authority collection in the Wodonga Historical Society. Wodonga's drinking water and wastewater operations were originally managed by the Wodonga Waterworks Trust, which was established in 1897, after Wodonga became a separate shire in 1876. In 1923 a Wodonga Waterworks Trust referendum to provide funding for new infrastructure to supply more water of better quality to Wodonga was passed. This included building the Wodonga Water Tower and it was completed in 1924. It supplied water to Wodonga until 1959, when it was drained and decommissioned after the No 1 Basin on Huon Hill was completed in 1958. In 1983 the Wodonga Waterworks Trust and the Wodonga Sewerage Authority became part of the Wodonga Council. And by 1989 a filtration plant at Huon Hill was completed, which provided filtered water of improved quality to Wodonga, in accordance with the World Health Organisation’s guidelines. In 1994 the Kiewa Murray Region Water Authority took over the Wodonga Council’s water and wastewater operations, and then in 1999 the Kiewa Murray Region Water Authority combined with the Ovens Region Water Authority and became the North East Region Water Authority or NERWA. NERWA then became known as North East Water.

The Yokohama Diving Company was established in the early 20th century. Their helmets were initially inspired by the english Siebe Gorman helmets which they manufactured in a smaller size. This also resulted in a smaller volume helmet allowing the divers to use less lead weights when diving. In the early nineteen sixties Yokohama became involved in manufacturing their own helmets but in a different design after american diving equipment manufacturer Robert Kirby had rebuilt several Yokohama helmets into a more practical / modern design.
