Timothy Lane
Timothy Lane (June 1734–5 July 1807) was a British inventor and scientist. His father was an apothecary, and Timothy followed in his footsteps, becoming a member of London’s Society of Apothecaries in 1757. His scientific interests were far-reaching; he was as curious about natural philosophy and chemistry as he was about medicine and botany. He was particularly interested in experiments and research on the uses of electricity that were being conducted by colleagues like Joseph Priestley. In the 1760s, Lane invented an instrument that could measure the strength of the electricity discharged from a Leyden jar. Benjamin Franklin Benjamin Franklin ( April 17, 1790) was an American polymath who was active as a writer, scientist, inventor, statesman, diplomat, printer, publisher, and political philosopher.

Joseph Priestley
Joseph Priestley (; 24 March 1733 – 6 February 1804) was an English chemist, natural philosopher, separatist theologian, grammarian, multi-subject educator, and liberal political theorist. He published over 150 works, and conducted experiments in electricity and other areas of science. He was a close friend of, and worked in close association with Benjamin Franklin involving electricity experiments. Priestley is credited with his independent discovery of oxygen by the thermal decomposition of mercuric oxide, having isolated it in 1774. During his lifetime, Priestley's considerable scientific reputation rested on his invention of carbonated water, his writings on electricity, and his discovery of several "airs" (gases), the most famous being what Priestley dubbed "dephlogisticated air" (oxygen). Priestley's determination to defend phlogiston theory and to reject what would become the chemical revolution eventually left him isolated within the scientific community. ...

Leyden Jar
A Leyden jar (or Leiden jar, or archaically, sometimes Kleistian jar) is an electrical component that stores a high-voltage electric charge (from an external source) between electrical conductors on the inside and outside of a glass jar. It typically consists of a glass jar with metal foil cemented to the inside and the outside surfaces, and a metal terminal projecting vertically through the jar lid to make contact with the inner foil. It was the original form of capacitor (also called a ''condenser''). Its invention was a discovery made independently by German cleric Ewald Georg von Kleist on 11 October 1745 and by Dutch scientist Pieter van Musschenbroek of Leiden (Leyden), Netherlands in 1745–1746. The Leyden jar was used to conduct many early experiments in electricity, and its discovery was of fundamental importance in the study of electrostatics. It was the first means of accumulating and preserving electric charge in large quantities that could be discharged at the ...

Henry Cavendish
Henry Cavendish ( ; 10 October 1731 – 24 February 1810) was an English natural philosopher and scientist who was an important experimental and theoretical chemist and physicist. He is noted for his discovery of hydrogen, which he termed "inflammable air". He described the density of inflammable air, which formed water on combustion, in a 1766 paper, ''On Factitious Airs''. Antoine Lavoisier later reproduced Cavendish's experiment and gave the element its name. A shy man, Cavendish was distinguished for great accuracy and precision in his researches into the composition of atmospheric air, the properties of different gases, the synthesis of water, the law governing electrical attraction and repulsion, a mechanical theory of heat, and calculations of the density (and hence the mass) of the Earth. His experiment to measure the density of the Earth (which, in turn, allows the gravitational constant to be calculated) has come to be known as the Cavendish experiment. Early life ...

Royal Society
The Royal Society, formally The Royal Society of London for Improving Natural Knowledge, is a learned society and the United Kingdom's national academy of sciences. The society fulfils a number of roles: promoting science and its benefits, recognising excellence in science, supporting outstanding science, providing scientific advice for policy, education and public engagement and fostering international and global co-operation. Founded on 28 November 1660, it was granted a royal charter by King Charles II as The Royal Society and is the oldest continuously existing scientific academy in the world. The society is governed by its Council, which is chaired by the Society's President, according to a set of statutes and standing orders. The members of Council and the President are elected from and by its Fellows, the basic members of the society, who are themselves elected by existing Fellows. , there are about 1,700 fellows, allowed to use the postnominal title FRS ( Fellow of ...

Edward Nairne
Edward Nairne (1726 – 1 September 1806) was English optician and scientific instrument maker. Biography Nairne was born in Sandwich, England. He was apprenticed to the optician Matthew Loft in 1741 and established his own business at 20 Cornhill in London after Loft's death in 1748. In 1774 he took his apprentice Thomas Blunt into partnership, a relationship that lasted until 1793 when Blunt opened his own shop at 22 Cornhill. Nairne patented several electrical machines, including an electrostatic generator consisting of a glass cylinder mounted on glass insulators; the device can supply either positive or negative electricity, and was intended for medicinal use. In the eighth edition of the instruction manual for this device he claimed that "electricity is almost a specific in some disorders, and deserves to be held in the highest estimation for its efficacy in many others". He recommended its use for nervous disorders, bruises, burns, scales, bloodshot eyes, toothache, sci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Philosophical Society
The American Philosophical Society (APS), founded in 1743 in Philadelphia, is a scholarly organization that promotes knowledge in the sciences and humanities through research, professional meetings, publications, library resources, and community outreach. Considered the first learned society in the United States, it has about 1,000 elected members, and by April 2020 had had only 5,710 members since its creation. Through research grants, published journals, the American Philosophical Society Museum, an extensive library, and regular meetings, the society supports a variety of disciplines in the humanities and the sciences. Philosophical Hall, now a museum, is just east of Independence Hall in Independence National Historical Park; it was designated a National Historic Landmark in 1965. History The Philosophical Society, as it was originally called, was founded in 1743 by Benjamin Franklin, James Alexander, Francis Hopkinson, John Bartram, Philip Syng, Jr. and others a ...

Society Of Apothecaries
The Worshipful Society of Apothecaries of London is one of the livery companies of the City of London. It is one of the largest livery companies (with over 1,600 members in 2012) and ranks 58th in their order of precedence. The society is a member of the London Museums of Health & Medicine and its guild church is the Church of St Andrew-by-the-Wardrobe. The Society's modern roles include educational, charitable and social activities, in addition to supporting the City of London, its governance and the Lord Mayor of the City of London. History Prior to the foundation of the Society in 1617, London apothecaries were in the Grocers' Company (founded 1345, and whose trade was described in 1365 as the "Mistery of Grossers, Pepperers and Apothecaries"). In the 14th and 15th centuries, the Grocers, Pepperers, Spicers and Apothecaries were the trades constituting the Fraternity of St Anthony. Before that, apothecaries had been Spicer-Apothecaries or Spicers since the 12th century. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hampstead
Hampstead () is an area in London, which lies northwest of Charing Cross, and extends from the A5 road (Roman Watling Street) to Hampstead Heath, a large, hilly expanse of parkland. The area forms the northwest part of the London Borough of Camden, a borough in Inner London which for the purposes of the London Plan is designated as part of Central London.
