Herman Boerhaave
Herman Boerhaave (Dutch: [ˈɦɛrmɑm ˈbuːrˌɦaːvə], 31 December 1668 – 23 September 1738) was a Dutch chemist, botanist, Christian humanist, and physician. He is sometimes regarded as the founder of clinical teaching and of the modern academic hospital along with Venetian physician Santorio Santorio (1561–1636). Boerhaave introduced the quantitative approach into medicine, along with his pupil Albrecht von Haller (1708–1777). He was the first to isolate the chemical urea from urine. He was the first physician to put thermometer measurements to clinical practice. His motto was Simplex veri sigillum: 'Simplicity is the sign of the truth'. He is often hailed as the "Dutch Hippocrates".
Boerhaave was born at Voorhout near Leiden. The son of a Protestant pastor, in his youth Boerhaave studied for a divinity degree and wanted to become a preacher. After the death of his father, however, he was offered a scholarship and he entered the University of Leiden, where he took his master's degree in philosophy in 1690, with a dissertation titled De distinctione mentis a corpore (On the Difference of the Mind from the Body). There he attacked the doctrines of Epicurus, Thomas Hobbes and Baruch Spinoza. He then turned to the study of medicine. He earned his medical doctorate from the University of Harderwijk (present-day Gelderland) in 1693, with a dissertation titled De utilitate explorandorum in aegris excrementorum ut signorum (The Utility of Examining Signs of Disease in the Excrement of the Sick).
In 1701 he was appointed lecturer on the institutes of medicine at Leiden; in his inaugural discourse, De commendando Hippocratis studio, he recommended to his pupils that great physician as their model. In 1709 he became professor of botany and medicine, and in that capacity he did good service, not only to his own university, but also to botanical science, by his improvements and additions to the botanic garden of Leiden, and by the publication of numerous works descriptive of new species of plants.
On 14 September 1710, Boerhaave married Maria Drolenvaux (1686–1746), the daughter of the rich merchant, Alderman Abraham Drolenvaux. They had four children, of whom one daughter, Maria Johanna (1712–1791) – wife of German art collector with various influential political ties Frederic Count de Thoms (1696–1746), lived to adulthood. In 1722, he began to suffer from an extreme case of gout, recovering the next year.
In 1714, when he was appointed rector of the university, he succeeded Govert Bidloo in the chair of practical medicine, and in this capacity he introduced the modern system of clinical instruction. Whether he was the first to do so is contested; in the words of one medical historian, Boerhaave "was neither an innovator of this practice, nor an especially energetic practitioner of it", though he did help to popularize the method. Four years later he was appointed to the chair of chemistry as well. In 1728 he was elected into the French Academy of Sciences, and two years later into the Royal Society of London. In 1729 declining health obliged him to resign the chairs of chemistry and botany; and he died, after a lingering and painful illness, at Leiden.
His reputation so increased the fame of the University of Leiden, especially as a school of medicine, that it became popular with visitors from every part of Europe. All the princes of Europe sent him pupils, who found in this skilful professor not only an indefatigable teacher, but an affectionate guardian.[citation needed] When Peter the Great went to Holland in 1716 (he had been in Holland before in 1697 to instruct himself in maritime affairs), he also took lessons from Boerhaave. Voltaire travelled to see him, as did Carl Linnaeus, who became a close friend and named the genus Boerhavia for him. In one probably apocryphal story to show the reach of Boerhaave's fame, a man from China sent him a letter addressed only "to Mr. Boerhaave, physician in Europe," and it reached him in due course.
The operating theatre of the University of Leiden in which he once worked as an anatomist is now at the centre of a museum named after him; the Boerhaave Museum. Asteroid 8175 Boerhaave is named after Boerhaave. From 1955 to 1961 Boerhaave's image was printed on Dutch 20-guilder banknotes. The Leiden University Medical Centre organises medical trainings called Boerhaave-courses.
He had a prodigious influence on the development of medicine and chemistry in Scotland. British medical schools credit Boerhaave for developing the system of medical education upon which their current institutions are based. Every founding member of the Edinburgh Medical School had studied at Leyden and attended Boerhaave's lectures on chemistry including John Rutherford and Francis Home. Boerhaave's Elementa Chemiae (1732) is recognised as the first text on chemistry.
