The year 1812 in science and technology involved some significant events, listed below.
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.
Lactose, or milk sugar, is a disaccharide composed of galactose and glucose and has the molecular formula C12H22O11. Lactose makes up around 2–8% of milk (by mass). The name comes from lact (gen. lactis), the Latin word for milk, plus the suffix -ose used to name sugars. The compound is a white, water-soluble, non-hygroscopic solid with a mildly sweet taste. It is used in the food industry.
Pterodactylus is a genus of extinct pterosaurs. It is thought to contain only a single species, Pterodactylus antiquus, which was the first pterosaur to be named and identified as a flying reptile and one of the first prehistoric reptiles to ever be discovered.

Samuel Thomas von Sömmerring was a German physician, anatomist, anthropologist, paleontologist and inventor. Sömmerring discovered the macula in the retina of the human eye. His investigations on the brain and the nervous system, on the sensory organs, on the embryo and its malformations, on the structure of the lungs, etc., made him one of the most important German anatomists.
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.
William Reid Clanny FRSE was an Irish physician and inventor of a safety lamp.
Ferdinand Adolph Theophil Hueppe was a German physician, bacteriologist and hygienist. From 1900 to 1904, he was the first Deutscher Fußball-Bund president.
Events from the year 1812 in the United Kingdom. The United Kingdom is still involved in the Napoleonic Wars with France and its attempts to stop French trade lead to the War of 1812 with the United States. Lord Wellington is active in the Peninsular War in Spain. This year also marks the only assassination of a British prime minister when Spencer Perceval is shot.
A mining lamp is a lamp, developed for the rigid necessities of underground mining operations. Most often it is worn on a hard hat in the form of a headlamp.
