Gottfried Christoph Beireis
Gottfried Christoph Beireis (2 March 1730 – 18 September 1809) was a German chemist and doctor. He was also a collector of curiosities who rescued some of Jacques de Vaucanson's automata. Biography Beireis was born in Mühlhausen. He taught anatomy, medicine, surgery, chemistry, botany, natural history, pharmacy, mineralogy, metallurgy, agriculture, forestry, music, painting, and numismatics. As a student, he discovered a way to convert ammonium sulfide to cinnabar and made a fortune selling the latter as a red dye. Beireis was a student of Georg Erhardt Hamberger's in Jena in 1753. Beireis became a professor in 1759 without having obtained his MD degree; the degree was awarded subsequently for work done at Helmstadt under Lorenz Heister between 1756 and 1759.

Ammonium Sulfide
Ammonium hydrosulfide is the chemical compound with the formula . Composition It is the salt derived from the ammonium cation and the hydrosulfide anion. The salt exists as colourless, water-soluble, micaceous crystals. On Earth the compound is encountered mainly as a solution, not as the solid, but ice is believed to be a substantial component of the cloud decks of the gas-giant planets Jupiter and Saturn, with sulfur produced by its photolysis responsible for the color of some of those planets' clouds. It can be generated by mixing hydrogen sulfide and ammonia. Preparation Solutions of ammonium hydrosulfide can be prepared by passing hydrogen sulfide gas through concentrated ammonia solution. According to a detailed 1895 report, hydrogen sulfide reacts with concentrated aqueous ammonia solution at room temperature to give . When this species is cooled to 0 °C and treated with additional hydrogen sulfide, one obtains . An ice-cold solution of this substance kept at 0&nbs ...

Automaton
An automaton (; plural: automata or automatons) is a relatively self-operating machine, or control mechanism designed to automatically follow a sequence of operations, or respond to predetermined instructions.Automaton – Definition and More from the Free Merriam-Webster Dictionary http://www.merriam-webster.com/dictionary/automaton Some automata, such as bellstrikers in mechanical clocks, are designed to give the illusion to the casual observer that they are operating under their own power. Since long ago, the term is commonly associated with automated puppets that resemble moving humans or animals, built to impress and/or to entertain people. Animatronics are a modern type of automata with electronics, often used for the portrayal of characters in films and in theme park attractions. Etymology The word "automaton" is the latinization of the Ancient Greek , , (neuter) "acting of one's own will". This word was first used by Homer to describe an automatic door opening, or ...

Jacques De Vaucanson
Jacques de Vaucanson (; February 24, 1709 – November 21, 1782) was a French inventor and artist who built the first all-metal lathe which was very important to the Industrial Revolution. The lathe is known as the mother of machine tools, as it was the first machine tool that led to the invention of other machine tools. He was responsible for the creation of impressive and innovative automata. He also was the first person to design an automatic loom. Early life De Vaucanson was born in Grenoble, France in 1709 as Jacques Vaucanson (the nobiliary particle "de" was later added to his name by the Académie des Sciences). The tenth child of a glove-maker, he grew up poor, and in his youth he reportedly aspired to become a clockmaker. He studied under the Jesuits and later joined the Order of the Minims in Lyon. It was his intention at the time to follow a course of religious studies, but he regained his interest in mechanical devices after meeting the surgeon Claude-Nicolas Le ...

Cinnabar
Cinnabar (), or cinnabarite (), from the grc, κιννάβαρι (), is the bright scarlet to brick-red form of mercury(II) sulfide (HgS). It is the most common source ore for refining elemental mercury and is the historic source for the brilliant red or scarlet pigment termed vermilion and associated red mercury pigments. Cinnabar generally occurs as a vein-filling mineral associated with recent volcanic activity and alkaline hot springs. The mineral resembles quartz in symmetry and in its exhibiting birefringence. Cinnabar has a mean refractive index near 3.2, a hardness between 2.0 and 2.5, and a specific gravity of approximately 8.1. The color and properties derive from a structure that is a hexagonal crystalline lattice belonging to the trigonal crystal system, crystals that sometimes exhibit twinning. Cinnabar has been used for its color since antiquity in the Near East, including as a rouge-type cosmetic, in the New World since the Olmec culture, and in ...

Holy Roman Empire
The Holy Roman Empire was a political entity in Western, Central, and Southern Europe that developed during the Early Middle Ages and continued until its dissolution in 1806 during the Napoleonic Wars. From the accession of Otto I in 962 until the twelfth century, the Empire was the most powerful monarchy in Europe. Andrew Holt characterizes it as "perhaps the most powerful European state of the Middle Ages". The functioning of government depended on the harmonic cooperation (dubbed ''consensual rulership'' by Bernd Schneidmüller) between monarch and vassals but this harmony was disturbed during the Salian period. The empire reached the apex of territorial expansion and power under the House of Hohenstaufen in the mid-thirteenth century, but overextending led to partial collapse. On 25 December 800, Pope Leo III crowned the Frankish king Charlemagne as emperor, reviving the title in Western Europe, more than three centuries after the fall of the earlier ancient West ...
