Johannes van Keulen was a scientific and navigational instrument maker, book seller and chart maker in Amsterdam, he was admitted to the booksellers guild in 1725. Johannes was the son of Gerard van Keulen, and the father of Gerard Hulst van Keulen. Johannes joined his father's firm 'In de Gekroonde Lootsman' in the Nieuwe Brugsteeg, in 1724. A year later, after his father's death Van Keulen took over the firm. From 1743 onwards he was the official chart maker of the Dutch East India Company (VOC), the following year he started making octants, and called himself mathematical instrument maker. Until his death in 1755 Johannes continued as cartographer, publisher, compass, backstaff and cross-staff maker. After his death in 1755, his wife (Catharina Buijs) took over the firm, together with their two sons, Gerard Hulst van Keulen and Cornelis Buijs van Keulen.

Biography:
Abraham de Casseres was born in Amsterdam. He was the son of a Portuguese clockmaker and received his training from Andreas Hohwü sr. and later from Asmus Johannsen in London. Around 1855, De Casseres started a clockmaker's workshop at the Rapenburg no.33 in Amsterdam with his partner Kiek. Business went well and soon he had so many customers (Royal Netherlands Navy, observatories and the merchant navy) that he had to hire seven craftsmen to get all the work done. After 1905, De Casseres bought his chronometers in London from Johannsen on which he placed his own dial. The firm of De Casseres was continued by his son J. de Casseres first also in Amsterdam and it existed in Rotterdam until 1939.

Klaas (or Claes) Jansz Vooght was a prominent mathematical practitioner. On 3 April 1662 he was admitted as surveyor by the Council of Holland and from about 1675 onward he was active as an instructor of navigation at Amsterdam. He was the author of a large number of works of navigation, including 'De dopgudze, ofte Een klare uytbreydingh des zons verscheynsichts' (Amsterdam 1676). He also published a translation of Euclid (1695) and a set of trigonometric tables. He designed a 'Quadrans Astromomicus', published in 1681. He contributed a translation of a Latin poem by Jeremiah Horrox to Dirck Rembrantsz entitled 'By-voeghsel op de Nederduytse Astronomia en sonne stilstant' (Amsterdam 1677), together with some poetry of his own. Moreover, in Dirck Rembrantsz' 'Antwoort op den brief van Jacobus Coccaeus' (Amsterdam 1661) there is a poem signed C. I. V.

Dirk van den Bosch was a mathematic and nautical instrument maker in Rotterdam, in the first half of the nineteenth century. His trade label was signed: 'Mathematische Instrumentmaker, op de Leuven Haven over de Leuvenbrug, oostzyde, te Rotterdam'. Another trade label depicts a sextant and an azimuth compass. A wooden measuring rod by Van den Bosch was made around 1850 for G.A. Escher, a civil engineer who just graduated from Delft University.

Johannes Loots was a cross-staff maker in Amsterdam, from 1691-1726, on the Zeedijk, and in the Nieuwe Brugsteeg, 'In de Jonge Lootsman'. He was an apprentice to cross-staff maker Hendrick Doncker. In 1691 Loots was recorded as mathematical instrument maker. In 1693 he was admitted to the booksellers guild and in 1695 he started selling charts, Johannes' oldest preserved cross-staff also dates from that year. After Loots' death, his widow Sara Swigters, and her brother Isaac Swigters, continued the firm until 1743 and 1750 respectively. She advertised as 'Weduwe van wijlen Johannes Loots konst- en kaartverkoopster'. After 1750 Hendrik Mooy purchased the remaining cross-staffs and continued that branch of the firm 'In de Jonge Lootsman'.

Biography:
Benjamin Ayres was an English scientific instrument maker who worked in Amsterdam, from about 1743 to about 1751. He was apprenticed to Jonathan Sisson between 1724-1731. In 1743 he published a description of his universal sundial, in Amsterdam. He collaborated with Mordechay Semah Aboab, also in Amsterdam, with whom he made an azimuth compass. In 1749, Ayres was appointed instrument maker to the Admiralty of Amsterdam, the VOC,and the WIC, and made responsible for introducing new techniques and standards to improve the quality of the navigating instruments, especially octants. He was appointed official instrument maker to the Dutch Stadholder, Prince Willem IV, but was dismissed a few years later. Following this Ayres left Amsterdam. Some years later, he worked for the King of Denmark. In 1757, Ayres returned to London where he was imprisoned, presumably for debt. After his release, he began working as an instrument maker, but he died soon afterwards.

Biography:
Jan Marten Kleman started making mathematical, optical, physical, nautical and astronomical instruments from his workshop on the Bergstraat in Amstyerdam, in 1781. In 1800 he moved his firm to the Nieuwendijk, first in 'In de Blauwe Bril' and later to 'In de Groene Bril'. In 1801 his fame had risen even more, and when others started imitating his instruments, Kleman started signing all his instruments. He was a member of the Felix Meritis Society since 1802, and appointed Instrument maker to the Royal Netherlands Navy in 1808. In 1809 his son Bernard joined the firm. In the same year, Kleman won a gold medal at an industrial exhibition ("Nijverheidstentoonstelling") in Amsterdam and his firm received the title Royal ("Koninklijk"). In 1820 Bernard died at a young age. Ten years later, in 1830, the business was taken over by Carel Swebilius, who in 1847 moved it to the Bantammersteeg no.16. In 1840 Kleman made a silver sextant for Prince Willem Frederik Hendrik.

Biography:
Jan van Musschenbroek was a physical, mathematical, anatomical and surgical instrument maker in Leiden. After the death of his father, Johan van Musschenbroek, Jan took over the workshop. Under his management it reached an absolute top. An unprecedented variety of instruments were offered in a series of priced catalogues. He was a nephew of Samuel van Musschenbroek, and brother of Petrus van Musschenbroek. Jan van Musschenbroek made a large number of instruments for Willem 's Gravesande, who used the instruments for lecture-demonstrations in experiments. He was the first to sell octants in the Dutch Republic.
