This diving helmet is part of a suit manufactured by the engineer Augustus Siebe (1788-1872) in 1837 and patented by him in 1839. The complete dress was watertight, representing an improvement on the earlier 'open dress' and was supplied with air from a pressure pump. The Siebe prototype became the model for all following diving helmets and, together with the suit, was of huge benefit to industries carrying out repairs on maritime structures. It could operate in depths of up to 100 metres.
