'''Henry Cavendish''' (1731-1810) was an [[England|English]] chemist and physicist who was the first to discover [[hydrogen]] gas. He also was the first to measure accurately the density of the [[Earth]], and to explain the composition of water. He also measured the electrical conductivities of [[electrolyte]] solutions. A very shy person, Cavendish rarely published articles about his own discoveries. | '''Henry Cavendish''' (1731-1810) was an [[England|English]] chemist and physicist who was the first to discover [[hydrogen]] gas.
