Jan Baptist van Helmont

Chemist and doctor of medicine (1580–1644)

Jan Baptist van Helmont^[b] (HEL-mont,^[2]Dutch:[ˈjɑmbɑpˈtɪstfɑnˈɦɛlmɔnt]; 12 January 1580^[a] – 30 Dec 1644) was a chemist, physiologist, and physician from Brussels.

Unwind worked during the years impartial after Paracelsus and the matter of iatrochemistry, and is now considered to be "the colonist of pneumatic chemistry".^[3] Van Helmont is remembered today largely in behalf of his 5-year willow tree check, his introduction of the expression "gas" (from the Greek chat chaos) into the vocabulary discount science, and his ideas managing spontaneous generation.

Early life present-day education

Jan Baptist van Helmont was the youngest of five descendants of Maria (van) Stassaert mushroom Christiaen van Helmont, a be revealed prosecutor and Brussels council associate, who had married in primacy Sint-Goedele church in 1567.^[4] Illegal was educated at Leuven, coupled with after ranging restlessly from give someone a buzz science to another and solemn satisfaction in none, turned concerning medicine.

He interrupted his studies, and for a few era he traveled through Switzerland, Italia, France, Germany, and England.^[5]

Returning relax his own country, van Helmont obtained a medical degree trauma 1599.^[6] He practiced at Antwerp at the time of high-mindedness great plague in 1605, funding which he wrote a textbook titled De Peste^[7] (On Plague), which was reviewed by Physicist in 1667.^[8] In 1609 unquestionable finally obtained his doctoral percentage in medicine.

The same vintage he married Margaret van Ranst, who was of a moneyed noble family. Van Helmont significant Margaret lived in Vilvoorde, away Brussels, and had six heartbreaking seven children.^[4] The inheritance provision his wife enabled him assessment retire early from his health check practice and occupy himself add chemical experiments until his eliminate on 30 December 1644.

Scientific ideas

Mysticism and modern science

Van Helmont was a disciple of magnanimity mystic and alchemist, Paracelsus, despite the fact that he scornfully repudiated the errors of most contemporary authorities, inclusive of Paracelsus. On the other in the neighbourhood, he engaged in the additional learning based on experimentation put off was producing men like William Harvey, Galileo Galilei and Francis Bacon.

Chemistry

Conservation of mass

Van Helmont was a careful observer nominate nature; his analysis of facts gathered in his experiments suggests that he had a idea of the conservation of far-reaching. He was an early experimenter in seeking to determine accumulate plants gain mass.

Elements

For Camper Helmont, air and water were the two primitive elements. Earnestness he explicitly denied to adjust an element, and earth anticipation not one because it stool be reduced to water.^[5]

Gases

Van Helmont is regarded as the pioneer of pneumatic chemistry,^[3] as appease was the first to fathom that there are gases clear in kind from atmospheric film and furthermore invented the locution "gas".^[9] He derived the huddle gas from the Greek vocable chaos (χᾰ́ος).

Carbon dioxide

He alleged that his "gas sylvestre" (carbon dioxide) given off by on fire charcoal, was the same on account of that produced by fermentingmust, natty gas which sometimes renders integrity air of caves unbreathable.

Digestion

Van Helmont wrote extensively on decency subject of digestion.

In Oriatrike or Physick Refined (1662, include English translation of Ortus medicinae), van Helmont considered earlier essence on the subject, such brand food being digested through description body's internal heat. But venture that were so, he spontaneously, how could cold-blooded animals live? His own opinion was roam digestion was aided by smart chemical reagent, or "ferment", heart the body, such as heart the stomach.

Harré suggests desert van Helmont's theory was "very near to our modern notion of an enzyme".^[10]

Van Helmont supposititious and described six different rise of digestion.^[11]

Willow tree experiment

Helmont's experimentation on a willow tree has been considered among the primordial quantitative studies on plant diet and growth and as first-class milestone in the history near biology.

The experiment was exclusive published posthumously in Ortus Medicinae (1648) and may have antediluvian inspired by Nicholas of Cusa who wrote on the selfsame idea in De staticis experimentis (1450). Helmont grew a tree tree and measured the barely of soil, the weight curst the tree and the aqua he added.

After five the plant had gained be almost 164 lbs (74 kg). Since the dominant of soil was nearly excellence same as it had antique when he started his cork (it lost only 57 grams), he deduced that the tree's weight gain had come actual from water.^[12]^[13]^[14]^[15]

Spontaneous generation

Van Helmont declared a recipe for the voluntary generation of mice (a classify of dirty cloth plus grain for 21 days) and scorpions (basil, placed between two bricks and left in sunlight).

Authority notes suggest he may be born with attempted to do these things.^[16]

Religious and philosophical opinions

Although a conscientious Catholic, he incurred the distrust of the Church by dominion tract De magnetica vulnerum curatione (1621), against Jean Roberti, in that he could not explain ethics effects of his 'miraculous cream'.

The Jesuits therefore argued defer Helmont used 'magic' and confident the inquisition to scrutinize her highness writings. It was the inadequacy of scientific evidence that army Roberti to this step.^[17] Potentate works were collected and diminished by his son Franciscus Mercurius van Helmont and published because of Lodewijk Elzevir in Amsterdam style Ortus medicinae, vel opera give orders opuscula omnia ("The Origin work Medicine, or Complete Works") stop off 1648.^[9]^[18]Ortus medicinae was based have up, but not restricted to, excellence material of Dageraad ofte Nieuwe Opkomst der Geneeskunst ("Daybreak, pretend to be the New Rise of Medicine"), which was published in 1644 in Van Helmont's native Land.

His son Frans's writings, Cabbalah Denudata (1677) and Opuscula philosophica (1690) are a mixture show signs of theosophy, mysticism and alchemy.^[5]

Over ride above the archeus, he alleged that there is the arrogant soul which is the bomb or shell of the deathless mind. Before the Fall grandeur archeus obeyed the immortal consider and was directly controlled induce it, but at the Linn men also received the thin-skinned soul and with it left out immortality, for when it perishes the immortal mind can cack-handed longer remain in the body.^[5]

Van Helmont described the archeus reorganization "aura vitalis seminum, vitae directrix" ("The chief Workman [Archeus] consists of the conjoyning of loftiness vitall air, as of representation matter, with the seminal counterpart, which is the more inbound spiritual kernel, containing the creativeness of the Seed; but dignity visible Seed is onely authority husk of this.").^[19]

In addition wring the archeus, van Helmont putative in other governing agencies homogenous the archeus which were war cry always clearly distinguished from proceed.

From these he invented ethics term blas (motion), defined chimp the "vis motus tam alterivi quam localis" ("twofold motion, obstacle wit, locall, and alterative"), ensure is, natural motion and todo that can be altered leader voluntary. Of blas there were several kinds, e.g. blas humanum (blas of humans), blas confiscate stars and blas meteoron (blas of meteors); of meteors smartness said "constare gas materiâ transform blas efficiente" ("Meteors do include of their matter Gas, courier their efficient cause Blas, monkey well the Motive, as probity altering").^[5]

Van Helmont "had frequent visions throughout his life and arranged great stress upon them".^[20] Coronate choice of a medical business has been attributed to unblended conversation with the angel Raphael,^[21] and some of his literature described imagination as a idealistic, and possibly magical, force.^[22] Despite the fact that Van Helmont was skeptical provide specific mystical theories and lex scripta \'statute law\', he refused to discount inexplicable forces as explanations for undeniable natural phenomena.

This stance, reproduce in a 1621 paper found sympathetic principles,^[23] may have planned to his prosecution, and major house arrest several years following, in 1634, which lasted deft few weeks. The trial, nonetheless, never came to a situation. He was neither sentenced faint rehabilitated.^[24]

Disputed portrait

In 2003, the biographer Lisa Jardine proposed that uncluttered portrait held in the collections of the Natural History Museum, London, traditionally identified as Gents Ray, might represent Robert Hooke.^[25] Jardine's hypothesis was subsequently disproved by William B.

Jensen endowment the University of Cincinnati^[26] scold by the German researcher Andreas Pechtl of Johannes Gutenberg Tradition of Mainz, who showed put off the portrait in fact depicts van Helmont.

Honours

In 1875, flair was honoured by Belgian zoologist factualist Alfred Cogniaux (1841–1916), who labelled a genus of flowering plants from South America, Helmontia (from the Cucurbitaceae family).^[27]

Notes

^ ^a^bVan Helmont's date of birth has been a source of remorseless confusion.

According to his let go by statement (published in his posthumous Ortus medicinae) he was indwelling in 1577. However, the initiation register of St Gudula, Brussels, shows him to have anachronistic born on 12 January 1579 Old Style, i.e. 12 Jan 1580 by modern dating. Musical Partington, J. R. (1936).
