Edwin Ruud (9 June 1854 – 9 December 1932) was a Norwegian-American mechanical engineer and inventor who immigrated to the United States where he designed, sold, and popularized the tankless water heater.
John Wright (1808–1844) was a surgeon from Birmingham, England who invented a process of electroplating involving potassium cyanide. The process was patented in 1840 by Wright's associate George Richards Elkington. He was born on the Isle of Sheppey, Kent and was apprenticed to a Dr Spearman in Rotherham, Yorkshire.

V&A Museum no. 481&A-1901 George Richards Elkington (17 October 1801 – 22 September 1865) was a manufacturer from Birmingham , England.
A water heater is still sometimes called a geyser in the UK and South Africa. Maughn's invention influenced the work of a Norwegian mechanical engineer named Edwin Ruud. The first automatic, storage tank-type gas water heater was invented around 1889 by Ruud after he immigrated to Pittsburgh, Pennsylvania (US). The Ruud Manufacturing Company ...
Mr. Baker claims that the particular mode of power used in creating the friction is not essential. It may be wind, water, gasoline, or any other source of energy. The most difficult part of the inventor's assertions to prove is that his system will light or heat a house at about half the cost of methods now in use. [5]
In 1802, Brugnatelli successfully carried out the first gilding electroplating experiments [4] with the coating of carbon electrodes by a metallic film, finally refining the process in 1805 for which he used his colleague Volta's invention of five years earlier, the voltaic pile, to facilitate the first electrodeposition. He hypothesized that ...
1869 Birdsill Holly fire-hydrant. Birdsill Holly Jr. (November 8, 1820 – April 27, 1894) was an American mechanical engineer and inventor of water hydraulics devices. He is known for inventing mechanical devices that improved city water systems and patented an improved fire hydrant that is similar to those used currently for firefighting.
Much of his work involved magnetic materials, reflective displays, and copper plating. While working for IBM, the inventor developed magnetic thin-film storage heads (co-invented with David Thompson in the 1970s), a revolutionary technology for recording and reading information on hard drives. [ 7 ]
