The year 1812 in science and technology involved some significant events, listed below.
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.
Lactose, or milk sugar, is a disaccharide sugar composed of galactose and glucose subunits 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.

Andreas Sigismund Marggraf was a German chemist from Berlin, then capital of the Margraviate of Brandenburg, and a pioneer of analytical chemistry. He isolated zinc in 1746 by heating calamine and carbon. Though he was not the first to do so, Marggraf is credited with carefully describing the process and establishing its basic theory. In 1747, Marggraf announced his discovery of sugar in beets and devised a method using alcohol to extract it. His student Franz Achard later devised an economical industrial method to extract the sugar in its pure form.
Carl Eduard Sachau was a German orientalist. He taught Josef Horovitz and Eugen Mittwoch.
Germanodactylus is a genus of germanodactylid pterodactyloid pterosaur from Upper Jurassic-age rocks of Germany, including the Solnhofen Limestone. Its specimens were long thought to pertain to Pterodactylus. The head crest of Germanodactylus is a distinctive feature.
Altmuehlopterus is a genus of pterosaur belonging to the Pterodactyloidea. It lived in the Late Jurassic of what is now Germany. It was formerly known as "Daitingopterus", a nomen nudum, informally coined in 2004.
The Göttingen Academy of Sciences is the oldest continuously existing institution among the eight scientific academies in Germany, which are united under the umbrella of the Union of German Academies of Sciences and Humanities. It has the task of promoting research under its own auspices and in collaboration with academics in and outside Germany. It has its seat in the university town of Göttingen. Its meeting room is located in the auditorium of the University of Göttingen.
Jost Benedum was a German historian of medecine.
