John Hall Gladstone

John Hall Gladstone (* March 7, 1827; † October 6, 1902 ) was a British chemist.

Gladstone was educated at University College London and at the University of Giessen. In 1850 he was a lecturer in chemistry at St Thomas' Hospital and in 1853 appointed at the age of 26 years as a Fellow of the Royal Society.

In 1858, he began with Thomas Pelham Dale, after the process of Marcelin Berthelot ( cf. Berthelot equation of state ), the work on the refractivity of liquid substances. Replace the expression of Newton ( from 1666) by the simpler formula ( n - l ) / d, which is influenced by the temperature slightly, but failed to change the physical state of the substance.

He was from 1874 to 1877 Fullerian Professor of Chemistry at the Royal Institution and 1874-1876 President of the Physical Society. From 1877 to 1879 he was President of the Chemical Society.

In 1897 he was awarded the Davy Medal.
