Dalziel Hammick

Dalziel Llewellyn Hammick FRS (born 8 March 1887, West Norwood, London, England, died 17 October 1966, was an English research chemist. His major work was in synthetic organic chemistry. He promulgated Hammick's rule, which predicts the order of substitution in benzene derivatives, while the Hammick reaction is used in the synthesis of larger molecules.

Overview

Hammick was educated at Oxford University and the University of Munich in Germany. After some years as a schoolmaster, in 1920 he was elected to a fellowship of Oriel College, Oxford.

His early research was on inorganic substances. He studied sulphur and its compounds and suggested structures for liquid and plastic sulphur. In 1922 he showed that the polymer polyoxymethylene results from the sublimation of trioxymethylene. It was not until the 1960s that this polymer was to be used commercially.

He also translated scientific books from French into English.

His work was honoured by election as a Fellow of the Royal Society in 1952.
