Sir Théodore Turquet de Mayerne (28 September 1573 – 22 March 1655) was a Genevan-born physician who treated kings of France and England and advanced the theories of Paracelsus.
Mayerne was born in a Huguenot family in Geneve, Republic of Geneva. His father was a Protestant French historian who had fled Lyon following the St. Bartholomew's Day Massacre and his godfather was Theodore Beza. Mayerne's first wife was Marguerite de Boetslaer and they had three children.
Mayerne studied first in Geneve and later moved to the University of Heidelberg. Later he moved to Montpellier to study medicine, graduated 1596 and received his doctorate in 1597. His dissertation defended the use of chemical remedies in medicine, under the guidance of Joseph du Chesne; this was the first intimation of his interest in Paracelsian theories. In May 1599, Mayerne joined Henri de Rohan, a Huguenot nobleman very powerful in Brittany, on his grand tour of Europe, visiting Germany, Italy, Bohemia, the Netherlands, England, and Scotland.During their visit to London in October 1600, Rohan and Mayerne were received by Queen Elizabeth I at her court, and in November 1600, when they reached Edinburgh, they were received by King James VI, before returning to France in early 1601. Despite his austere Calvinism, Mayerne greatly admired the many works of art and architecture he saw in his travels in Germany and Italy, especially liking the paintings of Albrecht Dürer and the Kunstkammer in Munich of curios kept by the Duke of Bavaria.
Mayerne moved to Paris, lecturer on anatomy and pharmacy and founded a medical practice. By that time he had begun to support the views of Paracelsus and used many chemical remedies. He kept detailed notes about his patients, among them Armand du Plessis, later Cardinal Richelieu, whom he treated for gonorrhea in 1605.
In 1600 French royal physician Jean Ribit de la Rivière (1571–1605) sponsored him to become one of the personal physicians, physician in ordinary, of the king Henri IV.His other pursuits were thwarted because he was not a Catholic and because most French physicians still followed the principles of Galen. In 1603 he tried to support his views to Medical Faculty of Paris, stating that his views were not opposed to Galenic and Hippocratic principles.
Despite their opposition, he retained the favour of the King, who appointed him to travel with the Duc de Rohan in his diplomatic missions to Germany and Italy. When the King intended to make Mayerne his first physician, the queen opposed the decision because Mayerne refused to convert to Catholicism. Mayerne continued in his lower post until 1606 when he sold it to another physician.
At this time he continued his association with du Chesne and the circle of Hermeticists that had grown up around him. These devotees of Paracelsus believed they were reviving the wisdom of the mythical pre-Platonic natural philosophers - men known as the prisci theologi that included Zoroaster and Hermes Trismegistus. The alchemical nature of their experiments was greatly resented by Galenists at the University of Paris.
In the same year he briefly visited England by invitation and met James I. He became a physician of Anne of Denmark and was incorporated at Oxford on April 8, 1606. He probably spent the following years back in France.
When Henri IV was murdered in 1610, Mayerne moved to England, again by invitation. In 1611 he became first physician of James I and his queen, succeeding Martin Schöner. He also treated most members of the royal court, including Sir Robert Cecil and Henry Frederick, Prince of Wales. His inability to successfully treat those two individuals, together with his closeness to the scandal surrounding the murder of Sir Thomas Overbury coloured his first years in England. Nevertheless, he was sometimes sent on diplomatic missions to France.
Mayerne made extensive Latin notes describing his treatment of Anne of Denmark from 10 April 1612 to her death in 1619. Some of these were published in 1703.
In 1616 Mayerne was elected a Fellow of the Royal College of Physicians. He helped the Society of Apothecaries to obtain a royal charter separate from the Grocers and helped to found the Company of Distillers. He was knighted in 1624. Next year he briefly visited Switzerland, where he had become Baron Aubonne. Mayerne retained his post as a first physician after the accession of Charles I in 1625.
There were fears over her health of Henrietta Maria, and in July 1627 she travelled with Mayerne to take the medicinal spring waters at Wellingborough in Northamptonshire.
He successfully championed the effort to produce the first official pharmacopoeia, which would specify treatments that apothecaries should provide for specific ailments. In this he included chemical remedies, which were easier to introduce in Protestant England than in Catholic France.
In 1628 his wife died and in 1630 he married Elizabeth Joachimi. They had five children but only one daughter Mary from his first marriage survived to adulthood. At about this time he treated Oliver Cromwell for a variety of physical and emotional symptoms, including a severe depression. In response to the Plague of 1630, he suggested the institution of a centralized 'Office of Health', with free royal hospitals, trained officials, and regulatory power.
During the English Civil War Mayerne kept a low profile in his practice in London and retained the favour of the parliament. After the execution of Charles I in 1649, he became nominal physician to Charles II but soon retired to Chelsea.
Mayerne died at Chelsea on 22 March 1654 or 1655. He was buried in St Martin-in-the-Fields with most of his family and his godson Sir Theodore des Vaux sponsored a monument for him. Des Vaux later published Mayerne's medical notes in the book Praxis Medica in 1690.
Mayerne compiled the so-called 'de Mayerne manuscript' between 1620 and 1646 based on conversations with painters (and others). The manuscript includes contributions from Rubens, van Dyck, Mytens, Paul van Somer, and Cornelius Johnson.His estate included copious amount of medical manuscripts, including detailed notes about his patients, most of it in Latin and French; his patients ranged from John Donne to Oliver Cromwell. His papers are kept in the Royal College of Physicians.
His influence on the administration of medicine - including the first suggestion of socialized medicine in England, and the standardisation of chemical cures, has been widely recognised.
His 'Paracelsian' outlook, which viewed the world as 'abounding in chemical secrets waiting to be exploited', led him to devise projects to enhance Scottish coal mines, to reopen lead mines in Europe and to monopolize oyster beds. He made chemical and physical experiments, created pigments and cosmetics, introduced calomel to medical use and created black-wash (lotio nigra). It also led him to an interest in cooking, and he grew obese in later years.
In 1634, he wrote the introduction for and edited one of the first treatises ever published on Insects (usually attributed to Thomas Muffet), under the title Insectorum, sive minimorum animalium Theatrum: Olim ab Edoardo Wottono, Conrado Gesnero, Thomaque Pennio inchoatum: Tandem Tho. Moufeti Londinâtis operâ sumptibusque maximis concinnatum, auctum, perfectum: Et ad vivum expressis Iconibus suprà quingentis illustratum. Londini ex Officinâ typographicâ Thom. Cotes. Et venales extant apud Benjam. Allen, in diverticulo, quod Anglicè dicitur Popes-head Alley.
In 1701 Joseph Browne produced an edition of Mayerne's Latin casebooks which includes details of medical treatments given to several courtiers, documents concerning the final illness of Prince Henry, and a journal of his consultations with Anne of Denmark and Henrietta Maria.The edition is some respects unreliable with misleading punctuation.
Hugh Redwald Trevor-Roper, Baron Dacre of Glanton,, was an English historian. He was Regius Professor of Modern History at the University of Oxford.
Robert Fludd, also known as Robertus de Fluctibus, was a prominent English Paracelsian physician with both scientific and occult interests. He is remembered as an astrologer, mathematician, cosmologist, Qabalist and Rosicrucian apologist.
Paracelsus, born Theophrastus von Hohenheim, was a Swiss physician, alchemist, lay theologian, and philosopher of the German Renaissance.
Sir Thomas Browne was an English polymath and author of varied works which reveal his wide learning in diverse fields including science and medicine, religion and the esoteric. His writings display a deep curiosity towards the natural world, influenced by the scientific revolution of Baconian enquiry. Browne's literary works are permeated by references to Classical and Biblical sources as well as the idiosyncrasies of his own personality. Although often described as suffused with melancholia, his writings are also characterised by wit and subtle humour, while his literary style is varied, according to genre, resulting in a rich, unique prose which ranges from rough notebook observations to polished Baroque eloquence.
Sylph is a mythological air spirit. The term originates in the 16th-century works of Paracelsus, who describes sylphs as (invisible) beings of the air, his elementals of air.
The year 1573 in science and technology included many events, some of which are listed here.
Iatrochemistry is a branch of both chemistry and medicine. Having its roots in alchemy, iatrochemistry seeks to provide chemical solutions to diseases and medical ailments.
Paracelsianism was an early modern medical movement based on the theories and therapies of Paracelsus. It developed in the second half of the 16th century, during the decades following Paracelsus' death in 1541, and it flourished during the first half of the 17th century, representing one of the most comprehensive alternatives to learned medicine, the traditional system of therapeutics derived from Galenic physiology. Based on the principle of maintaining harmony between the microcosm, Man; and macrocosm, Nature.
Thomas Muffet was an English naturalist and physician. He is best known for his Puritan beliefs, his study of insects in regard to medicine, his support of the Paracelsian system of medicine, and his emphasis on the importance of experience over reputation in the field of medicine.
Mary Talbot, Countess of Shrewsbury (1556–1632) was the wife of Gilbert Talbot, 7th Earl of Shrewsbury.
Peder Sørensen, widely known by his Latinized name, Petrus Severinus (1542–1602), was a Danish physician, and one of the most significant followers of Paracelsus. His works include the major treatise Idea medicinae philosophicae (1571), which asserted the superiority of the ideas of Paracelsus to those of Galen. Severinus was a member of Denmark's intellectual elite. His education was supported by the Danish crown and his eventual appointment as royal physician conferred status and authority to his work and opinions. He was a contemporary and intellectual and personal associate of Tycho Brahe who likewise is associated with the evolution of chemistry during the seventeenth century. Daniel Sennert, a professor at Wittenberg wrote in 1619 that most chemical physicians followed the lead of Severinus and even referred to a “Severinian School” of medical theory, which was based on the philosophy of Paracelsus. Scholars including Jole Shackelford and Hiro Hirai have claimed that Severinus was an important predecessor of both Johann Baptista von Helmont and Pierre Gassendi.
William Paulet, 4th Marquess of Winchester was an English nobleman, the son of William Paulet, 3rd Marquess of Winchester and Anne or Agnes Howard. He was styled Lord St. John from 1576 to 1598. He was summoned to Parliament on 16 January 1581 in his father's barony as Lord St. John. On 24 November 1598, he succeeded his father as 4th Marquess of Winchester. Paulet experienced great financial difficulties arising from his magnificent style of living and his lavish entertainment of Elizabeth I at Basing House.
John Webster (1610–1682), also known as Johannes Hyphastes, was an English cleric, physician and chemist with occult interests, a proponent of astrology and a sceptic about witchcraft. He is known for controversial works.
Elizabeth Norris, 3rd Baroness Norreys of Rycote, suo jure was an English noblewoman and a baroness. She was the wife of Edward Wray, Groom of the Bedchamber to King James I of England, with whom she eloped in 1622, and incurred the king's displeasure as she was his ward. Elizabeth and her elopement was allegedly the inspiration for Orlando Gibbons Fantazies.
Joseph Duchesne or du Chesne (c.1544-1609) was a French physician. A follower of Paracelsus, he is now remembered for important if transitional alchemical theories. He called sugar toxic, saying: “Under its whiteness, sugar hides a great blackness.”
