Brand, Hennig

Hennig Brand (ca. 1630-1692 Left ( idealized picture by J. Wright). 

Phosphorus (P, [Ne]3.v23// ), symbol and name from the Greek word Ojj s(jopoe (bringer of light). Discovered (1669) by the German alchimist Hennig Brand, who extracted phosphorus from urine. 

Phosphorus - the atomic number is 15 and the chemical symbol is P. The name derives from the Greek phosphoros for bringing light , since white phosphorus oxidizes spontaneously in air and glows in the dark. This was also the ancient name for the planet Venus, when it appears before sunrise. It was discovered by the German merchant Hennig Brand in 1669. 

In 1669 a German physician, Hennig Brand (1630—1692), a proponent of ancient alchemy, attempted to extract gold from urine. He collected a bucketful of urine that he allowed to evaporate. He soon expanded his experiment to 60 buckets of urine placed all around the laboratory until they evaporated. He then proceeded to boil down the urine, filter it, and...

Elemental phosphorus was discovered in 1669 by Hennig Brand. About two hundred years later James Readman developed a process for phosphorus recovery from phosphatic rocks using an electric furnace.

Although the elements, gold (Au), silver (Ag), tin (Sn), copper (Cu), lead (Pb), mercury (Hg), antimony (Sb), arsenic (As), carbon (C), iron (Fe), sulfur (S) and zinc (Zn) had been known since ancient times, the first scientific discovery of an element occurred in 1669, when Hennig Brand discovered phosphorus (P). During the next two hundred years various chemical and physical properties of elements and their compounds were studied by chemists. By 1869, a total of 63 elements had been discovered. As the number of known elements increased, scientists began to recognize patterns in properties and began to develop classification schemes.

Phosphorus was first discovered in 1669 by German physician Hennig Brand (ca. 1630-1692). Brand is somewhat famous in chemistry. He is sometimes called the last of the alchemists. Alchemy was a kind of pre-science that existed from about 500 bce to about the end of the I6th century. Alchemists wanted to find a way of changing lead, iron, and other metals into gold. They also wanted to find a way of having eternal life. Alchemy contained too much magic and mysticism to be a real science. But it developed a number of techniques and produced many new materials that were later found to be useful in modern chemistry. 

German physician Hennig Brand discovers phosphorus. 

It was discovered by an alchemist and merchant named Hennig Brand while he was searching for the philosopher s stone in Hamburg, Germany, in 1669. 

In 1669 Hennig Brand, a German alchemist, was attempting to recover, by means of intense heat, the gold he hoped was lurking in human urine. The waxy white substance that he did retrieve, which glowed green when exposed to air, was in fact elemental phosphorus. 

Phosphorus was first isolated by the alchemist Hennig Brand of Ham-bnrg aronnd 1670. He prepared white phosphorus, one of two common forms (allotropes) of the element, by evaporating human urine and strongly heating the residual sofids. White phosphorus distilled and was collected nnder water. 

In 1735 the cobalt ore used by the glass maker was examined by Georg Brandt, a Swede, born at Riddarhytta in Vestmanland in 1694, and not to be confused with Hennig Brand, the Hamburg merchant, who obtained phosphorus from urine in 1669 (p. 76). Brandt isolated a new metal from the mineral in impure form in 1742 and called it cobalt. That it was really a new metal was confirmed by Bergman in 1790 and by Tassaert in 1799. The real study of the chemistry of cobalt compounds began with the researches of Thenard in 1802 and of Proust in 1806.
