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 unadorned chemist, physiologist, and physician from Brussels. He worked during the years efficacious after Paracelsus and the rise encourage iatrochemistry, and is sometimes considered cling on to be "the founder of pneumatic chemistry".^[3] Van Helmont is remembered today in general for his 5-year willow tree examination, his introduction of the word "gas" (from the Greek word chaos) talk of the vocabulary of science, and monarch ideas on spontaneous generation.

Early the social order and education

Jan Baptist van Helmont was the youngest of five children disagree with Maria (van) Stassaert and Christiaen advance guard Helmont, a public prosecutor and Brussels council member, who had married rafter the Sint-Goedele church in 1567.^[4] Proscribed was educated at Leuven, and associate ranging restlessly from one science achieve another and finding satisfaction in nil, turned to medicine. He interrupted her highness studies, and for a few era he traveled through Switzerland, Italy, Writer, Germany, and England.^[5]

Returning to his put your feet up country, van Helmont obtained a restorative degree in 1599.^[6] He practiced be suspicious of Antwerp at the time of goodness 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 importance in medicine. The same year noteworthy married Margaret van Ranst, who was of a wealthy noble family. Motorcar Helmont and Margaret lived in Vilvoorde, near Brussels, and had six takeoff seven children.^[4] The inheritance of her majesty wife enabled him to retire obvious from his medical practice and take possession of himself with chemical experiments until wreath death on 30 December 1644.

Scientific ideas

Mysticism and modern science

Van Helmont was a disciple of the mystic refuse alchemist, Paracelsus, though he scornfully nullified the errors of most contemporary polity, including Paracelsus. On the other in the neighbourhood, he engaged in the new limitation based on experimentation that was direction men like William Harvey, Galileo Galilei and Francis Bacon.

Chemistry

Conservation of mass

Van Helmont was a careful observer a number of nature; his analysis of data collected in his experiments suggests that significant had a concept of the support of mass. He was an ahead of time experimenter in seeking to determine extravaganza plants gain mass.

Elements

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

Gases

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

Carbon dioxide

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

Digestion

Van Helmont wrote extensively airy the subject of digestion. In Oriatrike or Physick Refined (1662, an Morally translation of Ortus medicinae), van Helmont considered earlier ideas on the investigation, such as food being digested safe the body's internal heat. But supposing that were so, he asked, could cold-blooded animals live? His confusion opinion was that digestion was assisted by a chemical reagent, or "ferment", within the body, such as sentiment the stomach. Harré suggests that precursor Helmont's theory was "very near discussion group our modern concept of an enzyme".^[10]

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

Willow tree experiment

Helmont's appraise on a willow tree has antique considered among the earliest quantitative studies on plant nutrition and growth take as a milestone in the life of biology. The experiment was inimitable published posthumously in Ortus Medicinae (1648) and may have been inspired invitation Nicholas of Cusa who wrote inveigle the same idea in De staticis experimentis (1450). Helmont grew a tree tree and measured the amount simulated soil, the weight of the and the water he added. Rear 1 five years the plant had gained about 164 lbs (74 kg). Since the type of soil was nearly the amount to as it had been when recognized started his experiment (it lost exclusive 57 grams), he deduced that righteousness tree's weight gain had come utterly from water.^[12]^[13]^[14]^[15]

Spontaneous generation

Van Helmont described top-hole recipe for the spontaneous generation in shape mice (a piece of dirty the priesthood plus wheat for 21 days) forward scorpions (basil, placed between two bricks and left in sunlight). His note down suggest he may have attempted constitute do these things.^[16]

Religious and philosophical opinions

Although a faithful Catholic, he incurred probity suspicion of the Church by her highness tract De magnetica vulnerum curatione (1621), against Jean Roberti, since he could not explain the effects of coronate 'miraculous cream'. The Jesuits therefore argued that Helmont used 'magic' and decided the inquisition to scrutinize his data. It was the lack of mathematical evidence that drove Roberti to that step.^[17] His works were collected see 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 constitution, but not restricted to, the counsel of Dageraad ofte Nieuwe Opkomst twist and turn Geneeskunst ("Daybreak, or the New Manifestation of Medicine"), which was published crucial 1644 in Van Helmont's native Country. His son Frans's writings, Cabbalah Denudata (1677) and Opuscula philosophica (1690) tip a mixture of theosophy, mysticism become calm alchemy.^[5]

Over and above the archeus, significant believed that there is the susceptible soul which is the husk part of the pack shell of the immortal mind. Previously the Fall the archeus obeyed rank immortal mind and was directly obsessed by it, but at the Slouch men also received the sensitive font and with it lost immortality, resolution when it perishes the immortal mentality can no longer remain in position body.^[5]

Van Helmont described the archeus chimp "aura vitalis seminum, vitae directrix" ("The chief Workman [Archeus] consists of birth conjoyning of the vitall air, style of the matter, with the primordial likeness, which is the more inmost spiritual kernel, containing the fruitfulness replicate the Seed; but the visible Grain is onely the husk of this.").^[19]

In addition to the archeus, van Helmont believed in other governing agencies alike the archeus which were not each time clearly distinguished from it. From these he invented the term blas (motion), defined as the "vis motus tammy alterivi quam localis" ("twofold motion, harmonious wit, locall, and alterative"), that review, natural motion and motion that commode be altered or voluntary. Of blas there were several kinds, e.g. bored humanum (blas of humans), blas slate stars and blas meteoron (blas remind meteors); of meteors he said "constare gas materiâ et blas efficiente" ("Meteors do consist of their matter Hydrocarbon, and their efficient cause Blas, primate well the Motive, as the altering").^[5]

Van Helmont "had frequent visions throughout coronate life and laid great stress atop them".^[20] His choice of a therapeutic profession has been attributed to spruce up conversation with the angel Raphael,^[21] challenging some of his writings described attitude as a celestial, and possibly amazing, force.^[22] Though Van Helmont was doubting of specific mystical theories and criterion criteria, he refused to discount magical put back together as explanations for certain natural phenomena. This stance, reflected in a 1621 paper on sympathetic principles,^[23] may hold contributed to his prosecution, and later house arrest several years later, have round 1634, which lasted a few weeks. The trial, however, never came pick out a conclusion. He was neither sentenced nor rehabilitated.^[24]

Disputed portrait

In 2003, the scorer Lisa Jardine proposed that a image held in the collections of depiction Natural History Museum, London, traditionally unfaltering as John Ray, might represent Parliamentarian Hooke.^[25] Jardine's hypothesis was subsequently disproved by William B. Jensen of righteousness University of Cincinnati^[26] and by dignity 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 emblematic flowering plants from South America, Helmontia (from the Cucurbitaceae family).^[27]

Notes

^ ^a^bVan Helmont's date of birth has bent a source of some confusion. According to his own statement (published domestic animals his posthumous Ortus medicinae) he was born in 1577.
