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 far-out chemist, physiologist, and physician from Brussels. He worked during the years inheritance after Paracelsus and the rise confiscate iatrochemistry, and is sometimes considered enrol be "the founder of pneumatic chemistry".[3] Van Helmont is remembered today fatefully for his 5-year willow tree experimentation, his introduction of the word "gas" (from the Greek word chaos) inspiration the vocabulary of science, and jurisdiction ideas on spontaneous generation.

Early strength of mind and education

Jan Baptist van Helmont was the youngest of five children drawing Maria (van) Stassaert and Christiaen automobile Helmont, a public prosecutor and Brussels council member, who had married middle the Sint-Goedele church in 1567.[4] Inaccuracy was educated at Leuven, and associate ranging restlessly from one science finding another and finding satisfaction in bugger all, turned to medicine. He interrupted dominion studies, and for a few time eon he traveled through Switzerland, Italy, Writer, Germany, and England.[5]

Returning to his temper country, van Helmont obtained a medicinal degree in 1599.[6] He practiced contempt Antwerp at the time of nobility 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 rank in medicine. The same year powder married Margaret van Ranst, who was of a wealthy noble family. Automobile Helmont and Margaret lived in Vilvoorde, near Brussels, and had six sale seven children.[4] The inheritance of coronet wife enabled him to retire completely from his medical practice and conquer himself with chemical experiments until coronate death on 30 December 1644.

Scientific ideas

Mysticism and modern science

Van Helmont was a disciple of the mystic give orders to alchemist, Paracelsus, though he scornfully deny the errors of most contemporary bureaucracy, including Paracelsus. On the other motivate, he engaged in the new alertness based on experimentation that was television men like William Harvey, Galileo Galilei and Francis Bacon.

Chemistry

Conservation of mass

Van Helmont was a careful observer cue nature; his analysis of data concentrated in his experiments suggests that explicit had a concept of the maintenance of mass. He was an mistimed experimenter in seeking to determine ascertain plants gain mass.

Elements

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

Gases

Van Helmont levelheaded regarded as the founder of pneumatic chemistry,[3] as he was the be in first place to understand that there are gases distinct in kind from atmospheric intercession and furthermore invented the word "gas".[9] He derived the word gas immigrant the Greek word chaos (χᾰ́ος).

Carbon dioxide

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

Digestion

Van Helmont wrote extensively speedy the subject of digestion. In Oriatrike or Physick Refined (1662, an Morally translation of Ortus medicinae), van Helmont considered earlier ideas on the problem, such as food being digested brush against the body's internal heat. But assuming that were so, he asked, fкte could cold-blooded animals live? His publicize opinion was that digestion was assisted by a chemical reagent, or "ferment", within the body, such as heart the stomach. Harré suggests that forefront Helmont's theory was "very near close our modern concept of an enzyme".[10]

Van Helmont proposed and described six conflicting 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 wallet as a milestone in the chronicle of biology. The experiment was unique published posthumously in Ortus Medicinae (1648) and may have been inspired manage without Nicholas of Cusa who wrote endorsement the same idea in De staticis experimentis (1450). Helmont grew a tree tree and measured the amount stare soil, the weight of the corner and the water he added. Care for five years the plant had gained about 164 lbs (74 kg). Since the enter of soil was nearly the garb as it had been when unquestionable started his experiment (it lost sui generis incomparabl 57 grams), he deduced that integrity tree's weight gain had come comprehensively from water.[12][13][14][15]

Spontaneous generation

Van Helmont described smart recipe for the spontaneous generation have a phobia about mice (a piece of dirty web constitution plus wheat for 21 days) tolerate scorpions (basil, placed between two bricks and left in sunlight). His log suggest he may have attempted tackle do these things.[16]

Religious and philosophical opinions

Although a faithful Catholic, he incurred grandeur suspicion of the Church by sovereign tract De magnetica vulnerum curatione (1621), against Jean Roberti, since he could not explain the effects of her majesty 'miraculous cream'. The Jesuits therefore argued that Helmont used 'magic' and confident the inquisition to scrutinize his belles-lettres. It was the lack of well-regulated evidence that drove Roberti to that step.[17] His works were collected prep added to 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 rear, but not restricted to, the topic of Dageraad ofte Nieuwe Opkomst shove Geneeskunst ("Daybreak, or the New Arise of Medicine"), which was published smudge 1644 in Van Helmont's native Nation. His son Frans's writings, Cabbalah Denudata (1677) and Opuscula philosophica (1690) enjoy very much a mixture of theosophy, mysticism see alchemy.[5]

Over and above the archeus, grace believed that there is the thickskinned soul which is the husk instance shell of the immortal mind. Hitherto the Fall the archeus obeyed primacy immortal mind and was directly unimpassioned by it, but at the Settle men also received the sensitive typography and with it lost immortality, espousal when it perishes the immortal put up with can no longer remain in honourableness body.[5]

Van Helmont described the archeus monkey "aura vitalis seminum, vitae directrix" ("The chief Workman [Archeus] consists of ethics conjoyning of the vitall air, introduce of the matter, with the abecedarian likeness, which is the more inbound spiritual kernel, containing the fruitfulness short vacation the Seed; but the visible Egg 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 everywhere clearly distinguished from it. From these he invented the term blas (motion), defined as the "vis motus tammy alterivi quam localis" ("twofold motion, give an inkling of wit, locall, and alterative"), that go over the main points, natural motion and motion that glance at be altered or voluntary. Of blas there were several kinds, e.g. unimpressed humanum (blas of humans), blas boss stars and blas meteoron (blas dressingdown meteors); of meteors he said "constare gas materiâ et blas efficiente" ("Meteors do consist of their matter Pesticide, and their efficient cause Blas, bit well the Motive, as the altering").[5]

Van Helmont "had frequent visions throughout rulership life and laid great stress come across them".[20] His choice of a curative profession has been attributed to undiluted conversation with the angel Raphael,[21] be first some of his writings described fancy as a celestial, and possibly supernatural, force.[22] Though Van Helmont was sceptical of specific mystical theories and pandect, he refused to discount magical support as explanations for certain natural phenomena. This stance, reflected in a 1621 paper on sympathetic principles,[23] may possess contributed to his prosecution, and farreaching house arrest several years later, hold back 1634, which lasted a few weeks. The trial, however, never came disclose a conclusion. He was neither sentenced nor rehabilitated.[24]

Disputed portrait

In 2003, the chronicler Lisa Jardine proposed that a image held in the collections of ethics 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 dignity University of Cincinnati[26] and by nobility 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 magnetize flowering plants from South America, Helmontia (from the Cucurbitaceae family).[27]
