Diemerbroeck, Isbrand, De

, was born at Montfort, in the neighbourhood of Utrecht, Dec. 13, 1609. After taking his degree of doctor in medicine at Angers, he went to Nimeguen in 1636, and continued there, through that and the following years, practising during the plague, which all that time raged with greatviolence. This furnished him with observations on the nature and treatment of that disease, which he published at Amsterdam, in 1644, 4to; but as he pursued the injudicious plan of keeping the patients in close apartments, and gave them heating medicines, his practice was probably not so successful as his book, which has passed through many editions. In 1642 he went to Utrecht, ar>d was made professor extraordinary in medicine. His lectures in medicine, and in anatomy, procured him great credit, and were no less useful to the university, drawing thither a great conflux of pupils. In 1651, he was made ordinary professor; he was also twice appointed rector of the university, and continued in high esteem to the time of his death, which happened Nov. 17, 1674, when his funeral oration was pronounced by the learned Graevius. Although an Arminian in his religious tenets, the magistrates dispensed in his case with the laws which excluded persons of that persuasion from attaining academical honours. In 1649 he published “O ratio de reducenda ad Medicinam Chirurgia;” and in 1664, Disputationum practicarum pars prima et secunda, de morbis Capitis et Thoracis,“12mo, in which Haller says, there are some curious and useful observations. His” Anatoine | Corporis Humani,“which has passed through numerous editions, was first published in 1672, 4to, a compilation, interspersed with some original observations; but the plates are neither very elegant nor very correct. In 1G85, his works were collected and published tog-ether, at Utrecht, under the title of” Opera Omnia,“by his son Timanis de Diemerbroeck, in folio. This was reprinted in two volumes, 4to, and published at Geneva in 1687. It contains, besides the works above named,” A treatise on the Measles and Small-pox, a century of observations in medicine and surgery, and a third part of disputations containing accounts of diseases of the lower belly." ¹
