Brand kept his discovery secret, as alchemists of the time did, and worked with the phosphorus trying unsuccessfully to use it to produce gold. His recipe was: [5] Let urine stand for days until it gives off a pungent smell. [4] (This step was not necessary, as later scientists discovered that fresh urine yielded the same amount of phosphorus). [6]
Phosphorus is a finite (limited) resource that is widespread in the Earth's crust and in living organisms but is relatively scarce in concentrated forms, which are not evenly distributed across the Earth. The only cost-effective production method to date is the mining of phosphate rock, but only a few countries have significant commercial reserves.
Phosphorus: 1669 H. Brand: 1669 H. Brand Prepared and isolated from urine, it was the first element whose discovery date and discoverer are recorded. [53]
Hennig Brand (c. 1630 – c. 1710), discovery of phosphorus (around 1669). John Woodward (1665–1728), founder by bequest of the Woodwardian Professorship of Geology at Cambridge University. He collected and catalogued over 35 years nearly 10,000 specimens; they are in five walnut cabinets now in the Sedgwick Museum of Earth Sciences.
The Alchemist Discovering Phosphorus is a painting by Joseph Wright of Derby originally completed in 1771 then reworked in 1795. [1] The full title of the painting is The Alchymist, in Search of the Philosopher's Stone, Discovers Phosphorus, and prays for the successful Conclusion of his operation, as was the custom of the Ancient Chymical Astrologers.
Oil painting of Ambrose Godfrey. Ambrose Godfrey-Hanckwitz FRS (1660 – 15 January 1741), also known as Gottfried Hankwitz, also written Hanckewitz, or Ambrose Godfrey [1] [2] as he preferred to be known, was a German-born British phosphorus manufacturer and apothecary. [3]
The following dates are approximations. 700 BC: Pythagoras's theorem is discovered by Baudhayana in the Hindu Shulba Sutras in Upanishadic India. [18] However, Indian mathematics, especially North Indian mathematics, generally did not have a tradition of communicating proofs, and it is not fully certain that Baudhayana or Apastamba knew of a proof.
