Adriaan Paets Van Troostwijk
Adriaan Paets van Troostwijk (4 March 1752 – 3 April 1837) was a Dutch businessman amateur chemist. He conducted experiments and theorized on the nature of substances, conduct some of the earliest experiments on the electrolysis of water in collaboration with physician Johan Rudolph Deiman (1743–1808). Troostwijk was born in Utrecht to cloth-merchant Wouter van Troostwijk and Johanna Dolphina Paets. He married Marie Cornelia Loten in 1770 and joined the business of his father-in-law in Amsterdam until 1816 and lived in Niewersluis subsequently. Here he became a member of the ''Felix Meritis'', an Amsterdam organization of polymaths founded in 1777. Along with his physician friend Jan Deiman, he conducted experiments and wrote 35 papers between 1778 and 1818. The director of the Haarlem Teylers museum Martinus van Marum also collaborated with Paets van Troostwijk. Using an electrostatic generator, he was able to split water with gold as an electrode (acting as a catalyst as exa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johan Rudolph Deiman
Jan Rudolph Deiman or Johann Rudolf Deimann (29 August 1743 – 15 January 1808) was a German-Dutch physician and chemist who was among the first to examine electrolysis of water, and examine the application of electricity for medical uses along with Adriaan Paets van Troostwijk. In 1791, they founded the De Bataafsche Societeit (The Batavian Society) which later became the ''Gezelschap der Hollandsche Scheikundigen'' (Society of Dutch Chemists). Deiman was the youngest child of solicitor Albertus Deiman and Volke Hiddes in Hage, East Friesland. His mother died when he was a year old, and after the death of his father around 1758 he lived with his older brothers and apprenticed as an apothecary in Leer before studying medicine and philosophy in Halle with Adolph Böhmer. In 1770 he graduated after writing a ''Dissertatio inauguralis de indicatione vitali generetium'' and soon moved to practice medicine in Amsterdam. He studied philosophy and participated in discussions of learne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Utrecht
Utrecht ( , , ) is the fourth-largest city and a municipality of the Netherlands, capital and most populous city of the province of Utrecht.

It has been the religious centre of the Netherlands since the 8th century. It was the most important city in the Netherlands until the Dutch Golden Age, when it was surpassed by Amsterdam as the country's cultural centre and most populous city. Utrecht is home to Utrecht University, the largest university in the Netherlands, as well as several other institutions of higher education. Due to its central position within the country, it is an important hub for both rail and roa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teylers Museum
Teylers Museum () is an art, natural history, and science museum in Haarlem, Netherlands. Established in 1778, Teylers Museum was founded as a centre for contemporary art and science. The historic centre of the museum is the neoclassical Oval Room (1784), which was built behind the house of Pieter Teyler van der Hulst (1702–1778), the so-called ''Fundatiehuis'' (Foundation House). Pieter Teyler was a wealthy cloth merchant and banker of Scottish descent, who bequeathed his fortune for the advancement of religion, art, and science. He was a Mennonite and follower of the Scottish Enlightenment. History In his will, Pieter Teyler stipulated that his collection and part of his fortune should be used to establish a foundation for their promotion: Teylers Stichting. The Teyler legacy to the city of Haarlem was split into two societies: Teylers First or Theological Society (Dutch: ''Teylers Eerste of Godgeleerd Genootschap''), intended for the study of religion and Teylers Second ...

Martin Van Marum
Martin(us) van Marum (20 March 1750, Delft – 26 December 1837, Haarlem) was a Dutch physician, inventor, scientist and teacher, who studied medicine and philosophy in Groningen. Van Marum introduced modern chemistry in the Netherlands after the theories of Lavoisier, and several scientific applications for general use. He became famous for his demonstrations with instruments, most notable the '' Large electricity machine'', to show statical electricity and chemical experiments while curator for the Teylers Museum. Biography Early career Born in Delft, Van Marum moved to Haarlem in 1776 ''because the Haarlemmers had more taste in the sciences than anywhere else in the Netherlands.'' After his arrival in Haarlem he began to practise medicine, but devoted himself mainly to lecturing on physical subjects and creating instruments to demonstrate physical theory. He must have made a big impression on Haarlem society, because he became a member of the Dutch Society of Science in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phlogiston Theory
The phlogiston theory is a superseded scientific theory that postulated the existence of a fire-like element called phlogiston () contained within combustible bodies and released during combustion. The name comes from the Ancient Greek (''burning up''), from (''flame''). The idea was first proposed in 1667 by Johann Joachim Becher and later put together more formally by Georg Ernst Stahl. Phlogiston theory attempted to explain chemical processes such as combustion and rusting, now collectively known as oxidation. It was challenged by the concomitant weight increase, and was abandoned before the end of the 18th century following experiments by Antoine Lavoisier and others. Phlogiston theory led to experiments which ultimately concluded with the discovery of oxygen. Theory Phlogiston theory states that ''phlogisticated'' substances contain phlogiston and that they ''dephlogisticate'' when burned, releasing stored phlogiston which is absorbed by the air. Growing plants then absor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cornelis Rudolphus Theodorus Krayenhoff
Corneli(u)s Rudolphus Theodorus, Baron Krayenhoff ( Nijmegen, 2 June 1758 – Nijmegen, 24 November 1840) was a physicist, artist, general, hydraulic engineer, cartographer and – against his will and for only a short time – Dutch Minister of War. Biography His father was a hydraulic engineer and soldier in Nijmegen, with brewing as a sideline. Krayenhoff was educated in Nijmegen, Arnhem and Harderwijk. In the latter city he met Herman Willem Daendels, later a fellow-revolutionary. He had been intended to study law, but began to study philosophy and medicine instead (1777–1783). He wrote his dissertations on the '' theory of the imagination'' and a medical survey of the dysentery epidemic that raged in Nijmegen in 1783. He established himself as a physician in Amsterdam, after he had declined an offer of a professorate in medicine at Franeker university. He was a member of the ''Concordia et Libertate'' genootschap and of '' Maatschappij tot Nut van 't Algemeen''. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Year 175 ( CLXXV) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Piso and Iulianus (or, less frequently, year 928 '' Ab urbe condita''). The denomination 175 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
