A. E. H. (Alfred Edwin Howard) Tutton

Born in 1864, Alfred Edwin Howard Tutton was a British inspector of schools who built an impressive second career as a crystallographer. He studied at Oxford and became known for exceptionally careful work on the physical and optical properties of crystals, especially double sulfates and selenates.

His research was widely respected in Britain and abroad, and he was elected a Fellow of the Royal Society in 1899. The mineral tuttonite and the class of compounds often called Tutton's salts reflect the lasting influence of his work.

Tutton died in 1938, but his name remains closely tied to the development of crystallography at a time when exact measurement was transforming the field. He is remembered as a meticulous experimental scientist whose most important discoveries were made alongside a demanding public career in education.
