When did Johann Becher live and what was his contribution to chemistry?

Johann Joachim Becher, (born , Speyer, Bishopric of Speyer—died October 1682/85, England), chemist, physician, and adventurer whose theories of combustion influenced Georg Stahl's phlogiston theory.

What did Johann Becher discover?

- October 1682 Johann Joachim Becher was a German physician, alchemist, precursor of chemistry, scholar and adventurer, best known for his development of the phlogiston theory of combustion, and his advancement of Austrian cameralism.

What did Johann Joachim Becher do?

Becher was one of the most renowned chemists of 17th-century Germany, but he is remembered today mostly as the instigator of the notorious phlogiston theory. ... In his Physica subterranea of 1669, he proposed the existence of three new chemical principles or “earths”.

What year was the phlogiston theory proposed which in turn influenced the theory of oxygen combustion?

The name comes from the Ancient Greek φλογιστόν phlogistón (burning up), from φλόξ phlóx (flame). The idea was first proposed in 1667 by Johann Joachim Becher and later put together more formally by Georg Ernst Stahl.

What was the major evidence that supported the phlogiston theory?

In general, substances that burned in air were said to be rich in phlogiston; the fact that combustion soon ceased in an enclosed space was taken as clear-cut evidence that air had the capacity to absorb only a finite amount of phlogiston.

What is phlogiston theory why it was ruled out?

Stahl believed that the corrosion of metals in air (e.g., the rusting of iron) was also a form of combustion, so that when a metal was converted to its calx, or metallic ash (its oxide, in modern terms), phlogiston was lost. ...

Why the phlogiston theory is wrong?

Antoine Lavoisier, an eighteenth-century French chemist, disproved the theory of phlogiston by showing that combustion required a gas (oxygen) and that that gas has weight. ... So Becher had it backward: oxygen was being used up by the candle instead of phlogiston being given off by the flame.

Why did scientists discard the phlogiston theory?

Long ago, in the 1600s, scientists discarded the phlogiston theory because scientists wanted to explain things differently/new evidence didn't support it/it was too old and needed to be replaced. Among the different types of scientific knowledge, hypotheses are likely to be modified or discarded most frequently.

What was phlogiston used to explain?

Phlogiston theory attempted to explain chemical processes such as combustion and rusting, now collectively known as oxidation. It was challenged by the concomitant weight increase, and was abandoned before the end of the 18th century following experiments by Antoine Lavoisier and others.

What is the meaning of Becher?

What did Joachim Becher contribute to science?

• Johann Joachim Becher. His ideas and experiments on the nature of minerals and other substances were set forth in Subterranean Physics (1669). At Munich he suggested that the elector of Bavaria establish South American colonies and a cloth-trade monopoly, but angry merchants forced him to flee.

What did Joachim Becher mean by the three kinds of Earth?

• Johann Joachim Becher in 1669 set forth his view that substances contained three kinds of earth, which he called the vitrifiable, the mercurial, and the combustible. He supposed that, when a substance burned, combustible earth (Latin terra pinguis, meaning “fat earth”) was liberated.
