Biography:
Cartographer and hydraulic engineer. Cruquius was born in 1678, either on Vlieland or in Delft. His father was a mathematician and surveyor, who worked for the VOC chamber in Delft. In 1698, Nicolaas completed his education as a surveyor and started to make topographical maps, his most important work being a large wall map of Delfland in twenty-five parts. In 1716, he matriculated at Leiden University, where he worked with Herman Boerhaave. He was also active in meteorology. On 19 December 1705, he started to make meteorological measurements in Delft. First, he measured only atmospheric pressure, but soon he expanded his measurements to temperature and wind. From 1733 until his death in 1754, he continued these measurements as employee of the 'Hoogheemraadschap van Rijnland'. His main task for this organization was to manage the hydrology of the polders. Cruquius used his meteorological measurements to persuade the policy makers. He submitted a plan to the States of Holland to establish a meteorological institute. In this he was supported by three professors from Leiden University: Wittichius, 's Gravesande and Lulofs. Although the plan was rejected, Cruquius still played an important role in Dutch meteorology, by being the first to make a sustained and consistent series of meteorological observations. Another novelty was that Cruquius presented his data in graphs. He was also the first one to use symbols to present weather phenomena, such as wind and rain. He also made scientific instruments, such as a standard foot measure (the 'Rijnlandse voet'), made together with Jacob van Werven. In 1724 he was elected Fellow of the Royal Society of London.

Biography:
Christian Gottlob Heyne was born in 1729 and started his academic career in 1748 at the University of Leipzig. During these years and in the first years of his career he lived in poverty.. He first came to scholarly notice with his 1755 edition of Tibullus, written in Dresden while he worked in the library of Count von Bruhl (Graf Heinrich von Bruhl). In the following year, as the Seven Year War broke out, he published an edition of Epictetus. Heyne's academic career is most closely identified with the University of Gottingen. He went there in 1763 as both professor (of eloquence) and director of the university's library. During those years, he published numerous essays, trnaslations and other writings on classical literature, art and archeology. Of Heyne's numerous writings, the following may be mentioned. Editions, with copious commentaries of Tibullus (ed. SC Wunderlich, 1817), Virgil (ed. GP Wagner, 1830-1841), Pindar (3rd ed. by GH Schafer, 1817), Apollodorus, Bibliotheca Graeca (1803), Homer, Iliad (1802), Opuscula academica (1785-1812), containing more than hundred academical dissertations, of which the most valuable are those relating to the colonies of Greece and the antiquities of Etruscan art and history. His Antiquarische Aufsatze (1778-1779) is a collection of essays connected with the history of ancient art. Under his directorship the University Library became one of the leading academic libraries in the world, its collection growing from 60.000 to 200.000 volumes. This was mostly because of Heyne's extensive international network and zealous acquisition of works.

Biography:
Frits Zernike attended the HBS and from 1905 onwards studied chemistry at Amsterdam. At the age of nineteen, in 1907, he answered a prize question of the University of Groningen on probability theory, for which he was awarded a gold medal. He won a second gold medal for a prize question in optics issued by the Hollandsche Maatschappij van Wetenschappen in Haarlem (1912). In that year, he passed his doctoral examinations and started work on his dissertation, for which he used his prize winning essay of 1912 as a starting point. In 1913 he was appointed assistant to the astronomer J.C. Kapteyn at the University of Groningen. In 1915 he took his degree in chemistry at Amsterdam with a dissertation L'opalescence critique, théorie et experiments.
Shortly after obtaining his degree, also in 1915, Zernike succeeded Ornstein as lecturer in mathematical physics and theoretical mechanics in Groningen and in 1920 he became full professor. In the 1920's Zernike mainly worked in statistical physics. Together with Ornstein, and later with J.A. Prins, Zernike wrote a number of articles on fluctuation phenomena. In molecular statistics he introduced the concept of a radial distribution function, giving the mean number density of molecular centers around an arbitrary molecular center. For the Handbuch der Physik he wrote a chapter on probability theory and mathematical statistics (1928). In the 1930s, while not neglecting his work in statistical mechanics altogether, Zernike became more and more interested in physical optics. He had always been a very skillful instrument-maker: as early as 1921, he had constructed a very precise galvanometer and during the 1930s he worked on the construction of the so-called phase contrast microscope. He studied errors in telescope mirrors and discovered that there is a phase difference in the diffraction of light in different substances. By finding ways to increase the phase contrast, Zernike was able to construct a much more powerful microscope, with which one could study living material (staining usually kills the cells). In 1936 he obtained a patent on his invention. Zernike long remained a bachelor. In the 1920s he lived with his sister, Elisabeth Zernike, who was an author, and with his mother. Finally, only in January 1930, he married Theodora Willernina van Bommel van Vloten. They had one son (from an earlier marriage his wife already had one daughter). In February 1945, shortly before the liberation of Groningen, Zernike's wife died.
After the war Zernike, whose chair had been redefined as including mathematical and technical physics and theoretical mechanics in 1941, further refined his phase contrast microscope. In 1946 he was elected to the Royal Netherlands Academy of Arts and Sciences. In 1947-1948 he was visiting professor at Johns Hopkins University. Especially after 1950 he received honors all over the world, including in 1953 the Nobel Prize in physics for his phase contrast microscope. In 1956 he became a fellow of the Royal Society. In the year after receiving the Nobel Prize Zernike married to Lena Baanders, with whom he had no children. He retired in 1958 and in 1961 moved to Naarden (near Amsterdam). His interests were wide ranging, including secondary teaching, natural philosophy and religion. During the last years of his life he was ill and in 1953 he entered a hospital in Amersfoort, where he died on 10 March 1966.

In 1766, Banks made a botanical expedition to Labrador and Newfoundland to collect plants and other specimens with his friend Lieutenant Constantine Phipps. He took part in Captain James Cook's first expedition (1768-1771) on the Endeavour which explored the unchartered lands of the South Pacific and recorded observations on the Transit of Venus. The expedition circumnavigated the globe, enabling Banks to visit South America, Tahiti, New Zealand, Australia and Java, and New Zealand (1769-1770), where he collected specimens. Later Banks and Solander visited the Hebrides and Iceland together (1772). His collections and library were donated to the then British Museum after his death.

Banks was elected president of the Royal Society of London in 1778, a position he held for 41 years until his death in 1820.

Dissertation: Onderzoek der trillende platte vliezen

Highest degree: doctor

Fields of interest:
Biography:
Kapteyn was born in Barneveld, and grew up in a boarding school run by his parents, Gerrit Jacobus Kapteyn and the former Elisabeth Cornelia Koopmans. He was the ninth of fifteen children and family life was minimal because of his parents' running of the school. Whereas Kapteyn's older brother, Albertus Philippus (1848-1927) was judged by his father not to be suited for a higher education and was sent to a trade school (he became a well-known engineer, who ran Westinghouse Airbrake Europe), Jacobus showed his talents early and went to the University of Utrecht in 1868, at the age of 17. He took his Ph.D. in 1875 with a dissertation on Onderzoek der trillende platte vliezen (A Study of Vibrating Flat Membranes).
Kapteyn's first position was as observer at the Leiden Observatory (which because of Kaiser had become one of the foremost institutions for position measurements), but in 1877 he accepted the appointment to the new chair of astronomy at the university of Groningen. Had he remained at Leiden, he would undoubtedly have made his career as an observer. At Groningen, however, this was not an option: his requests for a well-equipped observatory fell on deaf ears because of opposition from the existing observatories at Leiden and Utrecht. Instead, he entered an arrangement with David Gill at the Cape Observatory: in Groningen, Kapteyn would measure the plates made by Gill's staff in their photographic Durchmusterung of the southern skies. For this work, Kapteyn designed precision instruments and organized an astronomical laboratory. The work began in 1885 and the positions of 450,000 southern stars thus measured appeared in three volumes between 1896 and 1900.
But stellar positions and brightnesses were only a means to an end. Like many other astronomers of his day, Kapteyn was interested in the distribution of stars and the structure of the Milky Way. By 1906, he had organized the international cooperative 'Plan of Selected Areas', in which the work of cataloguing the stars in 206 sample areas was divided among 30 observatories, a work that was not finished until almost half a century after Kapteyn's death. The information obtained was: apparent brightness, proper motion, radial motion, color, etc. Since the correlation of apparent brightness with distance had already been proven erroneous by William Herschel toward the end of his life, Kapteyn took a statistical approach: although the correlation was false for individual stars, it should apply for representative groupings of stars. By about 1920, as Kapteyn's career neared its end, enough information was becoming available to reveal a disk-like structure of the Milky Way, about six times as wide as thick, with the Sun near the center. Kapteyn was aware of the problem of extinction absorption of starlight by interstellar matter, but all his efforts to measure this were negative. The 'Kapteyn Universe' was therefore altered when absorption was demonstrated: its size had to be increased (although not as much as Harlow Shapley advocated) and the position of the Sun was determined, as argued by Shapley, to be eccentric. Kapteyn's program, however, retained its validity and was pursued by his successors. His study also showed that there were preferred motions of stars in the solar neighborhood, which showed relative motions of two groups of stars: this was important evidence that the Milky Way had a spiral structure and that our Sun was in one of the spiral arms.

After World War I, Kapteyn was one of a handful of scientists (see also Lorentz) who opposed the exclusion of German and Austrian scientists from international bodies and cooperative research, a practice not stopped until after his death. Kapteyn retired in 1921
