Gray was born in Belgravia, London, in 1827 and lived most of his life in London. In 1842, he entered as a student at St. George’s Hospital, London (then situated in Belgravia, now moved to Tooting), and he is described by those who knew him as a most painstaking and methodical worker, and one who learned his anatomy by the slow but invaluable method of making dissections for himself.
While still a student, Gray secured the triennial prize of Royal College of Surgeons in 1848 for an essay entitled The Origin, Connexions and Distribution of nerves to the human eye and its appendages, illustrated by comparative dissections of the eye in other vertebrate animals. In 1852, at the early age of 25, he was elected a Fellow of the Royal Society, and in the following year he obtained the Astley Cooper prize of three hundred guineas for a dissertation “On the structure and Use of Spleen.”
In 1858, Gray published the first edition of Anatomy, which covered 750 pages and contained 363 figures. He had the good fortune of securing the help of his friend Henry Vandyke Carter, a skilled draughtsman and formerly a demonstrator of anatomy at St. George’s Hospital. Carter made the drawings from which the engravings were executed, and the success of the book was, in the first instance, undoubtedly due in no small measure to the excellence of its illustrations. This edition was dedicated to Sir Benjamin Collins Brodie, Bart, FRS, DCL. A second edition was prepared by Gray and published in 1860. The book is still published under the title Gray's Anatomy and widely appreciated as an authoritative textbook for medical students.
Gray was struck by an attack of confluent smallpox, the most deadly type of the disease where individual lesions become so numerous that they join as a continuous, "confluent" sheet. He is assumed to have been infected due to his extended and meticulous caring for his ten-year-old nephew, Charles Gray, who did eventually recover. On the day he was to appear for an interview as a final candidate for a prestigious post at the St. George's Hospital, he died in London - 13 June 1861 - at the age of 34. He was buried at St James, Pancras and Highgate Cemetery. Gray had been vaccinated against smallpox as a child with one of the early forms of the vaccine.
Gray held successively the posts of demonstrator of Anatomy, curator of the museum and Lecturer of Anatomy at St. George’s Hospital and was in 1861 a candidate for the post of assistant surgeon.
