Dalziel Llewellyn Hammick FRS[1] (8 March 1887 in West Norwood, London, England – 17 October 1966) was an English research chemist. His major work was in synthetic organic chemistry. Along with Walter Illingworth he promulgated the Hammick-Illingworth rule, which predicts the order of substitution in benzene derivatives.[2] He also developed the Hammick reaction which generates ortho-substituted pyridines.[3][4][5]

The son of L. S. H. Hammick, Dalziel Hammick was educated at Whitgift School, Magdalen College, Oxford (where he was a demy), and at the University of Munich. He graduated Bachelor of Arts degree in Natural Sciences in 1910 and MA in 1921.[6]
At Oxford, he was a Cadet in the university's Officers' Training Corps, and in July 1911 he was commissioned as a second lieutenant for service with the Gresham's School OTC.[7]
After some ten years as a schoolmaster at Gresham's and Winchester, in 1920 Hammick was elected to a fellowship of Oriel College, Oxford, where he remained until his death in 1966. For most of his time at Oriel, he was also a lecturer in natural sciences at Corpus Christi College.
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.[8] It was not until the 1960s that this polymer was to be used commercially.
He also translated scientific books from French into English.
