Siebe Gorman

Siebe Gorman & Company Ltd was a British company which 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 and his son-in-law, Gorman.cite journal |last=Acott |first=C. |title=JS Haldane, JBS Haldane, L Hill, and A Siebe: A brief resume of their lives. |journal=South Pacific Underwater Medicine Society journal |volume=29 |issue=3 |date=1999 |issn=0813-1988 |oclc=16986801 |url=http://archive.rubicon-foundation.org/6016 |accessdate=2008-07-13 ]

It was notable for developing the "closed" diving helmet of the standard diving dress and associated equipment. As the helmet was sealed to the diving suit, it was watertight, unlike the previous "open" helmet systems. The new equipment was safer and more efficient and revolutionised underwater work from the 1830s.

Standard diving suit equipment was their main manufacturing operation, producing diving helmets in copper and brass. They also made frogman's equipment for the British armed forces during World War 2, and later, sport scuba gear. See makes of rebreather.

Siebe managed his business together with his son-in-law Gorman, and thus the company was called Siebe Gorman & Co.

Siebe Gorman and Co manufactured 12 bolt, 8 bolt, 6 bolt, 3 bolt, 2 bolt, no bolt, flange, and 12 bolt square corselet standard diving helmets.

Heinke Ltd in London also made diving gear and had connections with Siebe Gorman: see [http://www.divingheritage.com/heinke.htm this link] .

iebe plc

The non-diving engineering side of Siebe Gorman which latterly became Siebe plc carried the Siebe name until it merged with BTR plc to form Invensys in 1999.
