The Davy lamp is a safety lamp used in flammable atmospheres, invented in 1815 by Sir Humphry Davy. It consists of a wick lamp with the flame enclosed inside a mesh screen. It was created for use in coal mines, to reduce the danger of explosions due to the presence of methane and other flammable gases, called firedamp or minedamp.
Sir Humphry Davy, 1st Baronet, was a British chemist and inventor who invented the Davy lamp and a very early form of arc lamp. He is also remembered for isolating, by using electricity, several elements for the first time: potassium and sodium in 1807 and calcium, strontium, barium, magnesium and boron the following year, as well as for discovering the elemental nature of chlorine and iodine. Davy also studied the forces involved in these separations, inventing the new field of electrochemistry. Davy is also credited with discovering clathrate hydrates.
The voltaic pile was the first electrical battery that could continuously provide an electric current to a circuit. It was invented by Italian chemist Alessandro Volta, who published his experiments in 1799. Its invention can be traced back to an argument between Volta and Luigi Galvani, Volta's fellow Italian scientist who had conducted experiments on frogs' legs. Use of the voltaic pile enabled a rapid series of other discoveries, including the electrical decomposition (electrolysis) of water into oxygen and hydrogen by William Nicholson and Anthony Carlisle (1800), and the discovery or isolation of the chemical elements sodium (1807), potassium (1807), calcium (1808), boron (1808), barium (1808), strontium (1808), and magnesium (1808) by Humphry Davy.
1816 (MDCCCXVI) was a leap year starting on Monday of the Gregorian calendar and a leap year starting on Saturday of the Julian calendar, the 1816th year of the Common Era (CE) and Anno Domini (AD) designations, the 816th year of the 2nd millennium, the 16th year of the 19th century, and the 7th year of the 1810s decade. As of the start of 1816, the Gregorian calendar was 12 days ahead of the Julian calendar, which remained in localized use until 1923.

Siemens Brothers and Company Limited was an electrical engineering design and manufacturing business in London, England. It was first established as a branch in 1858 by a brother of the founder of the German electrical engineering firm Siemens & Halske. The principal works were at Woolwich where cables and light-current electrical apparatus were produced from 1863 until 1968. The site between the Thames Barrier and Woolwich Dockyard has retained several buildings of historic interest. New works were built at Stafford in 1903 and Dalston in 1908.
A safety lamp is any of several types of lamp that provides illumination in places such as coal mines where the air may carry coal dust or a build-up of inflammable gases, which may explode if ignited, possibly by an electric spark. Until the development of effective electric lamps in the early 1900s, miners used flame lamps to provide illumination. Open flame lamps could ignite flammable gases which collected in mines, causing explosions; safety lamps were developed to enclose the flame to prevent it from igniting the explosive gases. Flame safety lamps have been replaced for lighting in mining with sealed explosion-proof electric lights, but continue to be used to detect gases.
Josiah Latimer Clark FRS FRAS, was an English electrical engineer, born in Great Marlow, Buckinghamshire.
Events from the year 1816 in the United Kingdom.
Sir Francis Ronalds FRS was an English scientist and inventor, and arguably the first electrical engineer. He was knighted for creating the first working electric telegraph over a substantial distance. In 1816 he laid an 8-mile (13 km) length of iron wire between wooden frames in his mother's garden and sent pulses using electrostatic generators.
George John Singer (1786–1817) was an English early pioneer of electrical research, noted for his publications and for lectures delivered privately and at the Russell Institution.
Caleb Hillier Parry was an Anglo-Welsh physician credited with the first report of Parry–Romberg syndrome, published in 1815, and one of the earliest descriptions of the exophthalmic goiter, published in 1825.
Alexander Blair (1782–1878) was an English writer and academic. Considered as an original thinker, he is also described as "disorganised, despondent and a ditherer". He is known as a friend of Christopher North.
