During the first phase, in the 1780s, the claimants to the discovery (Antoine Lavoisier, Henry Cavendish, and James Watt) produced the work on which their claims were based.
Universal Gravitational Constant EX-9908 Page 2 of 13 Re-Written by Geoffrey R. Clarion the Earth to be determined. Cavendish's experiment was so well constructed that it was a hundred years before more accurate measurements were made. The gravitational attraction between a 15 gram mass and a 1.5 kg mass when their centers are
The English chemist and physicist Henry Cavendish, b. Oct. 10, 1731, d. Feb. 24, 1810, was the first to recognize hydrogen gas as a distinct substance. He also described the composition of water and made the first accurate measurement of the density of the Earth. Cavendish-Bentinck married, in 1882, Lady Olivia Caroline Amelia, daughter of Thomas Taylour, Earl of Bective, and granddaughter of the 3rd Marquess of Headfort.She was known as Lady Henry Bentick, and was mentioned in despatches (29 November 1900) by Lord Roberts, Commander-in-Chief, for civilian services during the Second Boer War. The English physicist and chemist Henry Cavendish determined the value of the universal constant of gravitation, made noteworthy electrical studies, and is credited with the discovery of hydrogen and the composition of water.
