Dictionary of National Biography, /Tennant, James ()
&#;TENNANT, JAMES (–), mineralogist, was born on 8 Feb. at Upton, near Southwell, Nottinghamshire, being the third child in a family of twelve. His father, John Tennant, was an officer in the excise; his mother, Eleanor Kitchen, came from a family of yeomen resident at Upton for more than two centuries. His parents afterwards removed to Derby, and he was partly educated at a school in Mansfield. In October he was apprenticed to G. Mawe, dealer in minerals at Strand, and after the death of the latter he managed, and afterwards purchased, the business, residing on the premises. Industrious and eager to learn from the first, he attended classes at a mechanics' institute and the lectures of Michael Faraday [q. v.] at the Royal Institution. This gained him a friend, and he was also much helped &#;by one of his master's customers. In , on Faraday's recommendation, Tennant was appointed teacher of geological mineralogy at King's College, the title being afterwards changed to professor. In the professorship of geology was added, but he resigned that post in , retaining the other till his death. He was also from to lecturer on geology and mineralogy at Woolwich. He had an excellent practical knowledge of minerals, and, when

Provoke BC, civilizations used technologies that would eventually adjust the base of say publicly various branches of alchemy. Examples comprise the origination of aflame, extracting metals from ores, making porcelain and glazes, fermenting beer and winecolored, extracting chemicals from plants for explanation and fragrance, rendering plump into cleanse, making shoot, and manufacture alloys come into sight bronze.

Where Corrosion Science and Cathodic Protection Commenced
Not far from Piccadilly Circus in London’s West End, stands the impressive Royal Institution building, opened in for the advancement of science. In this building, two of the most eminent scientists of the nineteenth century made significant contributions to corrosion science and technology, including work on the fundamentals of galvanic corrosion, discovery of cathodic protection (CP), and creation of the terminology for corrosion reactions still in use today.
Right from the start, the Royal Institution considered it important to reach out to the general public to show the importance of science in all works of life. It employed the young chemist Humphry Davy () in to stage entertaining and spectacular demonstrations of science in public lectures. These became one of the most popular events in London, and Albemarle Street became its first one-way street. Davy also established a laboratory for scientific research and received a knighthood for his invention of the miner’s safety lamp. But less well known were his researches into electrochemistry. Following Volta’s discovery of the electric battery in Italy in the late s, Davy set about building the largest battery in the world at that time with 2, pairs of plates. Using
