Ebenezer Kinnersley
Ebenezer Kinnersley (30 November 1711 – 4 July 1778]) was an English scientist, inventor and lecturer, specializing in the investigation of electricity. Life and Scientific Studies Ebenezer Kinnersley was a son of Rev. William Kinnersley, an assistant pastor of the Lower Dublin Baptist church. Ebenezer became a member of this church while young, and in 1743 was ordained as a minister, but he never served as a pastor. He travelled to America with his parents in 1714. His early life was passed at Dublin, and then he went to Philadelphia, where he gave evidence of his genius as a scholar and mechanician. It is supposed that he taught a school there and associated with Benjamin Franklin, who soon learned to appreciate young Kinnersley, whom he designates as "an ingenious neighbor." When Franklin saw Dr Spence, a Scotsman in Boston, experiment with a glass tube and silk, and observed the effects that were produced, he communicated the fact to his associates in Philadelphia, and ...

Gloucester, England
Gloucester ( ) is a cathedral city and the county town of Gloucestershire in the South West of England. Gloucester lies on the River Severn, between the Cotswolds to the east and the Forest of Dean to the west, east of Monmouth and east of the border with Wales. Including suburban areas, Gloucester has a population of around 132,000. It is a port, linked via the Gloucester and Sharpness Canal to the Severn Estuary. Gloucester was founded by the Romans and became an important city and ''colony'' in AD 97 under Emperor Nerva as '' Colonia Glevum Nervensis''. It was granted its first charter in 1155 by Henry II. In 1216, Henry III, aged only nine years, was crowned with a gilded iron ring in the Chapter House of Gloucester Cathedral. Gloucester's significance in the Middle Ages is underlined by the fact that it had a number of monastic establishments, including: St Peter's Abbey founded in 679 (later Gloucester Cathedral), the nearby St Oswald's Priory, Gloucester fo ...

Charles François De Cisternay Du Fay
Charles François de Cisternay du Fay (14 September 1698 – 16 July 1739) was a French chemist and superintendent of the Jardin du Roi. He discovered the existence of two types of electricity and named them "vitreous" and "resinous" (later known as positive and negative charge respectively). He noted the difference between conductors and insulators, calling them 'electrics' and 'non-electrics' for their ability to produce contact electrification. He also discovered that alike-charged objects would repel each other and that unlike-charged objects attract. He also disproved certain misconceptions regarding electric charge, such as that of Dr. Stephen Gray who believed that electric properties of a body depended on its colour. Du Fay's observations on electricity were reported in a paper written in December 1733 and printed in Volume 38 of the Philosophical Transactions of the Royal Society in 1734. He became a member of the French Academy of Sciences The French Acade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archibald Spencer
Archibald Spencer (January 1, 1698 – January 13, 1760) was a businessman, scientist, doctor, clergyman, and lecturer. He did seminars on science and for a while made a living at this. His lecture demonstrations were on medicine, light, and electricity. He is noted for introducing the phenomenon of electricity to Benjamin Franklin. As a businessman, he made investments in and helped form Anne Arundel County, Maryland. Early life Spencer was born on January 1, 1698, in Edinburgh, Scotland. Adam, his given name at birth, later changed to Archibald. Some writers on Benjamin Franklin's life have stated that Spencer was a medical doctor, and a male midwife. He specialized in diseases of the eye. Historian Nick Bunker claims he obtained his medical degree from the University of St Andrews of Scotland in 1739 by providing testimonials from two reputable physicians. Career Spencer was a businessman in the British Colonies of America. From 1743 to 1751 he professionally conducted sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Master Of Arts
A Master of Arts ( la, Magister Artium or ''Artium Magister''; abbreviated MA, M.A., AM, or A.M.) is the holder of a master's degree awarded by universities in many countries. The degree is usually contrasted with that of Master of Science. Those admitted to the degree have typically studied subjects within the scope of the humanities and social sciences, such as history, literature, languages, linguistics, public administration, political science, communication studies, law or diplomacy; however, different universities have different conventions and may also offer the degree for fields typically considered within the natural sciences and mathematics. The degree can be conferred in respect of completing courses and passing examinations, research, or a combination of the two. The degree of Master of Arts traces its origins to the teaching license or of the University of Paris, designed to produce "masters" who were graduate teachers of their subjects.

Giovanni Battista Beccaria
Giovanni Battista Beccaria (; 3 October 1716 – 27 May 1781), Italian physicist, was born at Mondovì, and entered the religious Order of the Pious Schools or Piarists, in 1732, where he studied, and afterward taught, grammar and rhetoric. At the same time, he applied himself with success to mathematics. He became professor of experimental physics, first at Palermo and then at Rome, and was appointed to a similar position at Turin in 1748. He was afterwards made tutor to the young princes de Chablais and de Carignan, and continued to reside principally at Turin during the remainder of his life. In May 1755 he was elected a fellow of the Royal Society of London, and published several papers on electrical subjects in the '' Phil. Trans.''. In 1759, King Charles Emmanuel III of Sardinia, who had invited him to Turin, employed him to measure the degree of meridian arc in Piedmont. Beccaria did much, in the way both of experiment and exposition, to spread a knowledge of the elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Prie ...
