Biography:
Bakhuys Roozeboom was the son of Jan Hendrik Bakhuys Roozeboom, who was a bookkeeper, and Maria Rensen. From 1868 to 1872 Bakhuys Roozeboom attended the HBS in Alkmaar and afterwards studied Greek and Latin, until in 1874 he passed the examination for admission to the university of Leiden. In the meantime, he had also assisted J.M. van Bemmelen, who was director of an HBS at Arnhem, in his chemical research on the soil of the new IJpolders near Amsterdam. Since Bakhuis Roozeboom did not have the financial means to study at Leiden, he became an analytical chemist in The Hague.
In 1878 however, Van Bemmelen, who had become professor of chemistry at Leiden, was able to appoint him as his research assistant and so offered him the opportunity to study chemistry after all. A year later Bakhuis Roozeboom married Catharina Elisabeth Wins, who gave birth to four sons and two daughters. In 1882 Bakhuys Roozeboom passed his doctoral examination and in 1884 received his doctorate with a dissertation of only 20 pages Over de hydraten van zwaveligzuur, chloor, broom en chloorwaterstof (On the Hydrates of Sulphurous Acid, Chlorine, Bromine and Hydrochloric Acid). In this dissertation he studied the relationship between the three states of matter at different temperatures and pressures. From 1881 to 1896 he earned a living as a teacher at an HBS for girls in Leiden.
In 1886 J.D. van der Waals drew his attention to the work of J. Willard Gibbs in thermodynamics, especially his phase rule of 1876, which defines the conditions of equilibrium as a relationship between the number of components of a system and the number of coexisting phases. This rule provided Bakhuys Roozeboom with a theoretical basis for his experimental work on heterogeneous equilibria, which he had begun to study in 1882. The first result was his article 'Sur les differentes formes de l'équilibre chimique hétérogène'(1887). Because of his admission as a privat-dozent in 1889 and his appointment as lecturer in physical chemistry in 1893 at Leiden, he had the opportunity to study all kinds of equilibria with his students, among whom F.A.H. Schreinemakers was the most important. In 1890 he was elected as a member of the Royal Academy Arts and of Sciences.
In 1896 Bakhuys Roozeboom succeeded Van 't Hoff as professor of chemistry at Amsterdam, where he continued the research on heterogeneous equilibria he had begun at Leiden. But he also continued the research school Van 't Hoff had founded at Amsterdam. As Van 't Hoff did before, Bakhuys Roozeboom stimulated his Ph.D. students to work out the details of his theory and each year two or three of them took their degree under his supervision. The results were summarized in Die heterogenen Gleichgewichte vom Standpunkte der Phasenlehre, the first and second volumes of which appeared in 1901 and 1904. After his death some of his pupils and collaborators (E.H. Buchner, A.H.W. Aten, F.A.H. Schreinemakers) continued this publication. In addition to his theoretical work, Bakhuys Roozeboom was also active in practical science: for example, he analyzed drinking water and developed a chemical method to clean paintings that were affected by vapours from the canals in Amsterdam. Since most scientists in the late nineteenth century separated science from religion, it was remarkable that Bakhuys Roozeboom openly confessed to be a Christian scientist. In 1895 he was one of the founders of the Christelijke Vereeniging van Natuur- en Geneeskundigen in Nederland (Christian Association of Scientists and Physicians in the Netherlands).

Biography:
Snellen enrolled at Leiden University in 1748 as a student in law. In 1750 he settled in Dordrecht, where he had inherited Develsteijn (a small castle outside the city), from his uncle Adam van Broeckhuysen (d. 1748), a skilled mechanic and clock maker. It was this uncle who probably had introduced the young Snellen in the craft of making time pieces and sundails. In 1758 Snellen became burgomaster of Dordrecht. In that capacity he was the head of the city clockworks. According to Schotel (1840) this was the reason he got interested in precision time pieces. He grew into a talented amateur instrument maker and designed chronometers and sundials. Again according to Schotel (1840) these instrument were (partly?) made by the horologist Steven Hoogendijk in Rotterdam and the Dordrecht watch maker of Italian decent Civati. In the 1770s Snellen presented a chronometer made by his own design to the Dutch stadholder, prince William V. This was the first chronometer ever made in the Netherlands. In 1791 Snellen bequeathed precision astronomical clocks to two Dutch institutions: (1) the Rotterdam Genootschap voor Proefondervindelijke Wijsbegeerte, and (2) the Leyden Astronomical Observatory. Only the latter has survived. A Snellen chronometer was auctioned in 2004 in New York as part of the inventory of the former Time Museum.

Biography:
Martinus van Marum was the son of Petrus van Marum and Cornelia van Oudheusden. The van Marum family stemmed from Groningen and belonged to the Reformed church. His father was land surveyor and agricultural specialist. From 1744 to 1764 he owned a delftware factory art Delft where he worked as master potter. Van Marum attended the primary school and Latin school at Delft. After the return of the family to Groningen, in 1664, he matriculated at Groningen university to study philosophy and medicine.
Among his teachers there were Petrus Camper (medicine and botany), Dionysius van de Wijnpersse (physics), Wouter van Doeveren (medicine, chemistry, and mineralogy), and Antonius Brugmans (philosophy, physics, and mathematics). Especially Camper was very influential, his views on botany aroused in van Marum a life-long interest in plants, and friendship with Camper until the latter's death in 1794. Contrary to the then common taxonomical studies, Camper advocated the study of the anatomy and physiology of the plant. In 1773 van Marum obtained the doctor's degree in philosophy on a highly praised thesis about the sap streams in plants. Later that year he graduated in medicine on a thesis in which he compared the physiology of sap streams in plants and animals.
Aspiring to a job as professor in botany van Marum was very disappointed when he was not elected to succeed Camper. He immediately turned his interests to the field of electricity. In 1776 he published a report on the technical improvements he introduced to the electrical machine. In the same year he went to Haarlem where he set up as a general practitioner (until 1780). The city of Haarlem appointed him as municipal lecturer in philosophy and medicine in 1776. Van Marum took this matter seriously: until 1780 he gave 52 public lectures on physical topics. In the context of Teyler's Foundation (see later) he would give another 163 lectures (until 1803). Until 1797 his subjects were mainly of a physico-chemical and technical nature, later he treated geological, mineralogical, and palaeontological issues.
In 1781 van Marum married the extremely wealthy printer's daughter Joanna Bosch (1739-1821), which made his possible for him to devote his life fully to the propagation and popularization of science. Thanks to his continuous and efficient activities, van Marum was able to make Haarlem a very important centre of Dutch science at the end of the eighteenth and the beginning of the nineteenth century. Van Marum used two institutions to reach his goals: the Dutch Society of Sciences (Hollandsche Maatschappij der Wetenschappen, founded in 1752), and Teyler's Foundation (founded in 1778 by the wealthy menist merchant Pieter Teyler van der Hulst).
Van Marum was appointed director of the Cabinet of Curiosities of the Dutch Society in 1777, he became its perpetual secretary in 1794. In 1784 he was appointed director of Teyler's Cabinet of Physical and Natural Curiosities and Library. All these functions he combined until his death. The personal and institutional wealth of both van Marum and the institutions made it him possible to expand the collections and libraries to a scale that made them famous all over Europe. From 1782 to 1802 he made a number of journeys abroad that brought him much fossil material and minerals. His most famous acquisitions were J.J. Scheuchzer's 'homo diluvii testis', actually a fossil salamander, the fossil Mosasaurus camperi, and Beringer's Lügensteine.
Apart from these activities van Marum was involved in scientific research too. His scientific ideas rested on two pillars: physico-theology, and utility. During the first half of his scientific life physico-theological interests prevailed, especially in his chemical research, his later works were mainly motiviated by utilitarian goals. In the Verhandelingen of Teyler's Foundation Van Marum published the results of many electrical and chemical experiments he had carried out with the largest electrical machine of the time. This spectacular machine was installed in 1784 in Teyler's Museum by its maker, the British instrument maker John Cuthbertson. It had two large, round glass plates each 1.65 metres in diameter. With this electrical machine he tried to discover the relationship between electricity and magnetism. Van Marum was a life long supporter of Benjamin Franklin's one fluid theory of electricity. The new Voltaic pile was quickly adopted by Van Marum, who named it after its Italian inventor.
His most important experiments, however, lay in the field of chemistry. In 1785 was the first to recognize a peculiar odour of electricity, which we now call ozone. Together with Adriaan Paets van Troostwijk he did experiments in the winters of 1785-1786 and 1786-1787 which were concentrated on the new combustion theory of the French chemist Antoine Laurent Lavoisier. These convinced him of the correctness of the new chemisty, and he became a staunch advocate of the Frenchman's ideas. In 1787 he published a summary of this oxidation theory, even before Lavoisier did so himself. With his newly developed gazometer he discovered carbon monoxide.
From 1802 onwards Van Marum's attention shifted to botany, concentrating on South African plants. For the prince of Salm-Dyck he compiled a systematic catalogue of his aloe collection, which reflected his renewed interest in plant systematics and taxonomy. However, his interest in the relation between electricity and magnetism caused him to repeat Oersted's famous experiments in 1822.
Van Marum was always interested in the practical and organisational aspects of science. He issued many competitions to write essays on scientific topics and took care of the publication of the prize-winning ones. During the French reign, king Louis Napoleon asked him, among others, to draft a constitution for a new national scientific institution, the Royal Institute of Science, Literature, and Arts (Koninklijk Instituut van Wetenschappen, Letteren en Schoone Kunsten), which was established in 1808. Until 1836 Van Marum was one of the most active members of this scientific institution. In 1814, the new king of the Netherlands, William I, appointed Van Marum to a commission for the restructuring of higher education, and in 1821 to a commission charged with the exploration of the possibilities of active control of the Dutch rivers.
As a physician Van Marum was a typical representative of the 'Aufklärungsarzt' (Enlightenment physician), who strived to make science and medicine subservient to the interests of society at large. In Van Marum's case this attitude was also stimulated by his belief in a practical form of christianity. Examples are his propagation of the use of pure oxygen to revive drowned persons, the use of steam baths for cholera patients, artificial ventilation in houses, factories and aboard ships, and the improvement of the digestor, originally invented by Denis Papin, to provide the poor with nutritive soups.
Van Marum maintained a large network of scientific contacts and correspondents throughout his life. He was a (corresponding) member of no less than 37 scientific societies in Europe and the United States. Van Marum died on 26 December 1837, honoured by Dutch and French societies, and leaving as his heir a natural son born in 1829.
Designed an electrostatic generator, with the help of Gerhard Kuyper from Groningen. Participated in development of the largest electrical machine of his time, designed by John Cuthberson.

Biography:
Optical instrument maker and natural philosopher, who invented the screw-barrel simple microscope in circa 1694. First to observe spermicide through a microscope. Hartsoeker worked most of his life in France. In 1699, when he returned to the Dutch Republic, he was elected member of the Academie Royale des Sciences and in 1704 of the Königlich-Preußische Akademie der Wissenschaften, in both cases as one of the first foreign members. When Czar Peter the Great visited Amsterdam, he was offered the chair of mathematics in St Petersburg. Hartsoeker rejected this offer, but later, in 1704, Hartsoeker accepted the position of "first mathematician and honorary professor of philosophy" at the University of Heidelberg, offered to him by Johann Wilhelm, Elector the Palatine. He returned to the Netherlands around 1720. The last years of his life were spent in Utrecht.
