Leslie Reginald Cox

Leslie Reginald Cox FRS (22 November 1897, Islington – 5 August 1965) was an English palaeontologist and malacologist.

Cox was born to parents who worked as government servants, in the Post Office telephone engineers' department. When he was still young, the family moved to Harringay, where he at age six started attendance at the South Harringay County School. In 1909, he entered Owen's School in Islington, one of the old London grammar schools.

Cox was elected a Fellow of the Royal Society in 1950. His nomination reads:

Dr. L.R. Cox is one of the leading authorities on fossil Lamellibranchiate and Gastropoda. His work at the British Museum has enabled him to study material from almost all parts of the world, and the results of his researches have been published in the transactions of learned bodies in at least ten countries. Although his contributions to Mesozoic and Cainozoic Palaeoconchology are widely recognised as important and sound, his work on the Jurassic Lamellibranchiata is outstanding. In addition to his systematic studies, he has made illuminating researches of an historical kind, especially in respect of the life and work of William Smith.

He was elected president of the Geologists' Association for 1954–56.

In August 1916, Cox began his war service.
