The Siebe Gorman Company can trace it roots back to the early 19th Century. Started by Augustus Siebe during the 1820s in London, England the company would work with Charles Dean to modify a smoke helmet into their first diving helmet. The company operated under the name A. Siebe during for much of the 19th Century. Later in the 1800s their name was changed to Siebe & Gorman and then Siebe Gorman & Co. In the early 20th Century it was updated to Siebe Gorman & Co Ltd, which it would stay until the late 1990s. If you have a helmet that was made by Siebe Gorman, please let us know, you might  be surprised just how much we can pay!
