===Start of modern diving===
* 1772: the first diving dress using a compressed-air reservoir was successfully designed and built in 1772 by ''Sieur''<ref>old French honorific for "sir" or "Mister"</ref> [[Fréminet]], a Frenchman from [[Paris]]. Fréminet conceived an autonomous breathing machine equipped with a helmet, two hoses for inhalation and exhalation, a suit and a reservoir, dragged by and behind the diver,<ref name="Musee de Scaphandre 3" /> although Fréminet later put it on his back.<ref name="Perrier 2008" />{{rp|46}} Fréminet called his invention ''machine hydrostatergatique'' and used it successfully for more than ten years in the harbours of [[Le Havre]] and [[Brest, France|Brest]], as stated in the explanatory text of a 1784 painting.<ref name="Cousteau 1955" /><ref name="Guienne" />
* 1774: [[John Day (carpenter)|John Day]] became the first person known to have died in an underwater accident while testing a "diving chamber" in [[Plymouth Sound]].<ref name="Tall" /><ref name="Ecott" />
* 1776: [[David Bushnell (inventor)|David Bushnell]] invented the [[American Turtle|''Turtle'']], first submarine to attack another ship. It was used in the [[American Revolution]].<ref name="Griswold 1820" />
* 1797: [[Karl Heinrich Klingert]] designed a full diving dress which consisted of a large metal helmet and similarly large metal belt connected by a leather jacket and pants.<ref name="Raanan 2010" />
* 1798: in June, F. W. Joachim, employed by Klingert, successfully completed the first practical tests of Klingert's armor.<ref name="All things diving" />
* 1800: [[Peter Kreeft (diver)|Captain Peter Kreeft]] of Germany dived several times with his helmet diving equipment to show it to King [[Gustav IV Adolf of Sweden]].<ref name="Historical diver" />
* 1800: [[Robert Fulton]] built a [[submarine]], the "[[Nautilus (1800)|Nautilus]]".<ref name="Dickinson 1913" />
* 1825: [[Johan Patrik Ljungström]] demonstrated his diving bell built of [[tinned]] [[copper]] with space for a crew of 2-3 persons, equipped with [[compass]] and methods of communication to the surface, successfully diving down to about 16 meters with Ljungström and an assistant on board, and wrote a book on the organization of private underwater diving<ref name="Jacobsen" /><ref name="History of diving 3" />
* c. 1831: American [[Charles Condert]] built an autonomous diving suit, using a copper pipe curved in the form of a horseshoe, displacing about 50 pounds of water, and worn at the waist, as an air reservoir which fed compressed air through a manually operated valve and a hose into an airtight rubberised hip length tunic with integral hood. Air escaped from a small hole in the hood. The buoyancy of the set required about 200 pounds of weight for ballast. Condert made several dives in the East River to about 20&nbsp;ft, and was drowned on his last dive in 1832.<ref name="Diving heritage Condert" />
* 1837: Captain William H. Taylor demonstrated his "submarine dress" at the annual [[American Institute Fair]] at Niblo's Garden, New York City.<ref name="Cox 2017" />
* 1839: 
** Canadian inventors James Eliot and Alexander McAvity of [[Saint John, New Brunswick]] patented an "oxygen reservoir for divers", a device carried on the diver's back containing "a quantity of condensed oxygen gas or common atmospheric air proportionate to the depth of water and adequate to the time he is intended to remain below".<ref name="Theriault 2001" />
** W.H.Thornthwaite of [[Hoxton]] in London patented an inflatable lifting jacket for divers.<ref name="hds4537" />
* Around 1842: The Frenchman [[Joseph-Martin Cabirol]] (1799–1874) formed a company in Paris and started making [[standard diving dress]].<ref name="hdt 2004" />
* 1843: Based on lessons learned from the Royal George salvage, the first diving school was set up by the Royal Navy.<ref name="Boot Camp" />
* 1845 James Buchanan Eads designed and built a diving bell and began salvaging cargo from the bottom of the Mississippi River, eventually working on the river bottom from the mouth of the river at the Gulf of Mexico to Iowa.<ref name="Christensen et al 1999" />
* 1856: [[Wilhelm Bauer]] started the first of 133 successful dives with his second submarine ''[[Seeteufel (Russia)|Seeteufel]]''. The crew of 12 was trained to leave the submerged ship through a diving chamber (airlock).<ref name="Elliott" />
* 1860: [[Giovanni Luppis]], a retired engineer of the Austro-Hungarian navy, demonstrated a design for a [[self-propelled torpedo]] to emperor [[Franz Joseph]].<ref name="Miskovic 2010" />
* 1864: ''[[H.L. Hunley]]'' became the first submarine to sink a ship, the USS ''Housatonic'', during the [[American Civil War]].<ref name="Neyland2005" />
* 1866: ''Minenschiff'', the first [[self-propelled torpedo]], developed by [[Robert Whitehead (engineer)|Robert Whitehead]] (to a design by Captain Luppis, Austrian Navy), was demonstrated for the imperial naval commission on 21 December.<ref name="Whitehead" />
* 1882: Brothers [[Carmagnolle diving suit|Alphonse and Théodore Carmagnolle]] of [[Marseille]], France, patented the first properly [[anthropomorphic]] design of ADS ([[atmospheric diving suit]]). Featuring 22 rolling convolute joints that were never entirely waterproof and a helmet with 25 {{convert|2|in|mm|adj=on}} glass viewing ports,<ref name="Historical Diving Times 2005" /> it weighed {{convert|380|kg|lbs}} and was never put in service.<ref name="Roc Roussey" />
