William Nicholson

Died 21 May 1815 (born 1753).English chemist who discovered the electrolysis of water (2 May 1800), the first observation of a chemical reaction caused by electricity. In his life, he was a hydraulic engineer, inventor, translator, and scientific publicist. He invented a hydrometer, an instrument for measuring the density of liquids (1790). In 1800, while he and Anthony Carlisle were investigating Volta's new voltaic pile battery, they stumbled upon the effect of electric current passing through water. Bubbles formed at the submerged ends of the wires. The gases turned out to be oxygen at the positive wire, and hydrogen at the negative. Water was broken down by electricity. This has become an important process with other compounds in the chemical industry.«
