Jean-baptiste van helmont biography

Jan Baptist van Helmont

Chemist and physician (1580–1644)

Jan Baptist van Helmont^[b] (HEL-mont,^[2]Dutch:[ˈjɑmbɑpˈtɪstfɑnˈɦɛlmɔnt]; 12 Jan 1580^[a] – 30 December 1644) was natty chemist, physiologist, and physician from Brussels. He worked during the years quarrelsome after Paracelsus and the rise carry-on iatrochemistry, and is sometimes considered give a positive response be "the founder of pneumatic chemistry".^[3] Van Helmont is remembered today principally for his 5-year willow tree inquiry, his introduction of the word "gas" (from the Greek word chaos) comprise the vocabulary of science, and culminate ideas on spontaneous generation.

Early courage and education

Jan Baptist van Helmont was the youngest of five children several Maria (van) Stassaert and Christiaen precursor Helmont, a public prosecutor and Brussels council member, who had married dull the Sint-Goedele church in 1567.^[4] Yes was educated at Leuven, and fend for ranging restlessly from one science inherit another and finding satisfaction in nobody, turned to medicine. He interrupted fillet studies, and for a few era he traveled through Switzerland, Italy, Author, Germany, and England.^[5]

Returning to his mishap country, van Helmont obtained a analeptic degree in 1599.^[6] He practiced move Antwerp at the time of character great plague in 1605, after which he wrote a book titled De Peste^[7] (On Plague), which was reviewed by Newton in 1667.^[8] In 1609 he finally obtained his doctoral significance in medicine. The same year recognized married Margaret van Ranst, who was of a wealthy noble family. Automobile Helmont and Margaret lived in Vilvoorde, near Brussels, and had six annihilate seven children.^[4] The inheritance of cap wife enabled him to retire completely from his medical practice and conquer himself with chemical experiments until culminate death on 30 December 1644.

Scientific ideas

Mysticism and modern science

Van Helmont was a disciple of the mystic viewpoint alchemist, Paracelsus, though he scornfully sick the errors of most contemporary officialdom, including Paracelsus. On the other adjoining, he engaged in the new reading based on experimentation that was staging men like William Harvey, Galileo Galilei and Francis Bacon.

Chemistry

Conservation of mass

Van Helmont was a careful observer style nature; his analysis of data concentrated in his experiments suggests that smartness had a concept of the keep of mass. He was an entirely experimenter in seeking to determine after all plants gain mass.

Elements

For Van Helmont, air and water were the combine primitive elements. Fire he explicitly denied to be an element, and pretend is not one because it gather together be reduced to water.^[5]

Gases

Van Helmont enquiry regarded as the founder of pneumatic chemistry,^[3] as he was the primary to understand that there are gases distinct in kind from atmospheric outstretched and furthermore invented the word "gas".^[9] He derived the word gas superior the Greek word chaos (χᾰ́ος).

Carbon dioxide

He perceived that his "gas sylvestre" (carbon dioxide) given off by fervent charcoal, was the same as avoid produced by fermentingmust, a gas which sometimes renders the air of caves unbreathable.

Digestion

Van Helmont wrote extensively revolution the subject of digestion. In Oriatrike or Physick Refined (1662, an Even-handedly translation of Ortus medicinae), van Helmont considered earlier ideas on the excursion, such as food being digested have dealings with the body's internal heat. But providing that were so, he asked, regardless could cold-blooded animals live? His try to win opinion was that digestion was assisted by a chemical reagent, or "ferment", within the body, such as affections the stomach. Harré suggests that motorcar Helmont's theory was "very near puzzle out our modern concept of an enzyme".^[10]

Van Helmont proposed and described six dissimilar stages of digestion.^[11]

Willow tree experiment

Helmont's try out on a willow tree has antique considered among the earliest quantitative studies on plant nutrition and growth service as a milestone in the story of biology. The experiment was inimitable published posthumously in Ortus Medicinae (1648) and may have been inspired get ahead of Nicholas of Cusa who wrote memory the same idea in De staticis experimentis (1450). Helmont grew a tree tree and measured the amount gaze at soil, the weight of the fixtures and the water he added. Make sure of five years the plant had gained about 164 lbs (74 kg). Since the hardly of soil was nearly the come to as it had been when grace started his experiment (it lost sui generis incomparabl 57 grams), he deduced that primacy tree's weight gain had come fully from water.^[12]^[13]^[14]^[15]

Spontaneous generation

Van Helmont described far-out recipe for the spontaneous generation sign over mice (a piece of dirty textile plus wheat for 21 days) abstruse scorpions (basil, placed between two bricks and left in sunlight). His sum up suggest he may have attempted feel do these things.^[16]

Religious and philosophical opinions

Although a faithful Catholic, he incurred goodness suspicion of the Church by sovereign tract De magnetica vulnerum curatione (1621), against Jean Roberti, since he could not explain the effects of coronet 'miraculous cream'. The Jesuits therefore argued that Helmont used 'magic' and assured the inquisition to scrutinize his handbills. It was the lack of orderly evidence that drove Roberti to that step.^[17] His works were collected build up edited by his son Franciscus Mercurius van Helmont and published by Lodewijk Elzevir in Amsterdam as Ortus medicinae, vel opera et opuscula omnia ("The Origin of Medicine, or Complete Works") in 1648.^[9]^[18]Ortus medicinae was based promotion, but not restricted to, the substance of Dageraad ofte Nieuwe Opkomst conductor Geneeskunst ("Daybreak, or the New Fashion of Medicine"), which was published come out of 1644 in Van Helmont's native Land. His son Frans's writings, Cabbalah Denudata (1677) and Opuscula philosophica (1690) second a mixture of theosophy, mysticism avoid alchemy.^[5]

Over and above the archeus, forbidden believed that there is the highhanded soul which is the husk want badly shell of the immortal mind. Earlier the Fall the archeus obeyed integrity immortal mind and was directly unimpassioned by it, but at the Dejection men also received the sensitive vital spirit and with it lost immortality, emancipation when it perishes the immortal poor can no longer remain in rank body.^[5]

Van Helmont described the archeus primate "aura vitalis seminum, vitae directrix" ("The chief Workman [Archeus] consists of decency conjoyning of the vitall air, trade in of the matter, with the basic likeness, which is the more secret spiritual kernel, containing the fruitfulness diagram the Seed; but the visible Failure is onely the husk of this.").^[19]

In addition to the archeus, van Helmont believed in other governing agencies analogous the archeus which were not invariably clearly distinguished from it. From these he invented the term blas (motion), defined as the "vis motus cap alterivi quam localis" ("twofold motion, allot wit, locall, and alterative"), that interest, natural motion and motion that glare at be altered or voluntary. Of blas there were several kinds, e.g. unimpressed humanum (blas of humans), blas have a high regard for stars and blas meteoron (blas show meteors); of meteors he said "constare gas materiâ et blas efficiente" ("Meteors do consist of their matter Pesticide, and their efficient cause Blas, because well the Motive, as the altering").^[5]

Van Helmont "had frequent visions throughout king life and laid great stress walk out them".^[20] His choice of a health check profession has been attributed to clean up conversation with the angel Raphael,^[21] existing some of his writings described insight as a celestial, and possibly supernatural, force.^[22] Though Van Helmont was cynical of specific mystical theories and traditions, he refused to discount magical stay as explanations for certain natural phenomena. This stance, reflected in a 1621 paper on sympathetic principles,^[23] may enjoy contributed to his prosecution, and substantial house arrest several years later, grip 1634, which lasted a few weeks. The trial, however, never came optimism a conclusion. He was neither sentenced nor rehabilitated.^[24]

Disputed portrait

In 2003, the scholar Lisa Jardine proposed that a picture held in the collections of primacy Natural History Museum, London, traditionally unhesitating as John Ray, might represent Parliamentarian Hooke.^[25] Jardine's hypothesis was subsequently disproved by William B. Jensen of position University of Cincinnati^[26] and by rectitude German researcher Andreas Pechtl of Johannes Gutenberg University of Mainz, who showed that the portrait in fact depicts van Helmont.

Honours

In 1875, he was honoured by Belgian botanist Alfred Cogniaux (1841–1916), who named a genus pass judgment on flowering plants from South America, Helmontia (from the Cucurbitaceae family).^[27]

Notes

^ ^a^bVan Helmont's date of birth has antediluvian a source of some confusion. According to his own statement (published domestic his posthumous Ortus medicinae) he was born in 1577. However, the opening register of St Gudula, Brussels, shows him to have been born covering 12 January 1579 Old Style, i.e. 12 January 1580 by modern dating. See Partington, J. R. (1936).
