Family background
Gotthilf Frederick Heinke was born in Meseritz, Prussia in 1786.[1] He arrived in London in 1809 and worked initially as a victualler to build up capital.[2] He married Sarah Smith,[3] who bore him three sons and two daughters. The sons were John William Heinke (born 1816), Charles Edwin Heinke (born 1818), and Gotthilf Henry Heinke (born 1820). John married Louisa Margaret Leathart in 1840
Ironmongery
In 1818, Gotthilf Frederick Heinke opened an ironmongery shop business in London and, in 1819, he got a workshop at 103 Great Portland Street in London.[lower-alpha 1] Gotthilf Frederick opened a second premises at 3 Old Jewry, London in 1839.
Start of making diving helmets
Around 1844, Charles Edwin Heinke made his first diving helmet. Inspired by William F. Saddler, Heinke started using solid brass for diving helmets' breastplates, instead of copper sheet. Heinke's diving helmets had three similarly shaped circular windows. They did not have the outer protective grills as in other helmets; thus they had better visibility for divers, and it was easier to keep the windows clean. Heinke's main competitor was Siebe Gorman who also made diving helmets, and Heinke constantly tried to improve on designs. He introduced an additional exhaust valve on the front side of the breastplate, which is now called the "peppermill" because of the holes in its cover. This exhaust made it possible for the diver to ascend and descend much faster.[citation needed][dubious – discuss]
In 1845, Charles brought in the "Pearler" helmet, with a square-pattern mould-cast (instead of oval and beaten) copper helmet. He became famous with this style. Their square breastplate made it easier for the diver to bend forwards to look for pearl oysters on the seabed. The idea was later copied by companies such as Siebe after Siebe took over Heinke, and even by Morse Diving in the USA.

WWII and after
- WWII blitz: Many company records were lost.
- 1950: After this date, the firm's fortunes declined, as with Siebe Gorman.
- Mid to late 1950s: the firm starts making "Heinke-Lung"[9] aqualungs, Delta[10] dry suits, Dolphin[11] and Falla[12] wetsuits, Hans Hass diving masks, swimming fins and snorkel tubes.

- 1961: The firm was incorporated into Siebe Gorman.[14][15] The last Heinke diving helmet went out of production in 1961. A few helmets were given the tag of "Siebe-Heinke", but eventually the name Heinke completely disappeared.
- 1967-1968: Siebe Gorman stops using the tradename 'Siebe Heinke'.
Unlike Siebe Gorman, who had only one series of serial numbers for their diving helmets, except for the last productions (which were meant most probably for the Russian Navy), Heinke used many series of serial numbers for them.
