1827–1902
A Victorian chemist with a gift for careful measurement, he helped connect chemistry with optics and spectroscopy at a time when those fields were rapidly expanding. He was also a prominent scientific organizer, leading both the Physical Society and the Chemical Society.

by J. H. (John Hall) Gladstone
Born in Hackney, London, on 7 March 1827, John Hall Gladstone became one of the notable British chemists of the nineteenth century. He studied at University College London and later earned a doctorate at Giessen, a major center for chemical research in Germany.
Gladstone is remembered for work that linked chemistry with light and measurement. His research ranged across physical chemistry, spectroscopy, and the optical properties of substances, and he also published on topics such as the chemistry of rubber. Alongside his laboratory work, he played an important part in the scientific world of his day, serving as president of the Physical Society and later of the Chemical Society.
He was elected a Fellow of the Royal Society in 1853 and remained active in science for decades. Gladstone died in London on 6 October 1902, leaving behind a reputation for steady, wide-ranging research and for helping shape the scientific institutions of Victorian Britain.
