Henry Littlejohn was born in Edinburgh in 1826 to Thomas Littlejohn, a confectioner of 33 Leith Street, and Isabella Duncan. He began his studies at the Perth Academy and the Royal High School, and continued them at the University of Edinburgh where he studied medicine, graduating with distinction in 1847. He was taught surgery by Prof Monro and Dr Robert Halliday Gunning.

Littlejohn served as Edinburgh's first Medical Officer of Health (1862–1908), introducing model sanitation improvements and the legal requirement to notify cases of infectious diseases. He contributed significantly to the public health movement in Edinburgh and to public health administration and also to urban management. He was assisted in later years by Dr Thomas William Drinkwater FRSE. Littlejohn also co-founded the Royal Hospital for Sick Children in Edinburgh.

Long a lecturer for the Royal College of Surgeons of Edinburgh at Surgeons' Hall, he was appointed to the Chair of Medical Jurisprudence at the University of Edinburgh in 1897.

Serving as Edinburgh's Police Surgeon from 1854 and as Medical Advisor to the Crown in Scotland in criminal cases, he was often called upon as an expert witness. From 1862 he was Edinburgh's first Medical Officer of Health.

A kirk elder at the High Kirk of Edinburgh, Littlejohn filled several prominent posts in public life, including nine years on the board of the Royal Infirmary of Edinburgh, president of the Royal College of Surgeons of Edinburgh (1875–76), president of the Medico-Chirurgical Society of Edinburgh (1883–85), and president of the Royal Institute of Public Health (1893).

Although Arthur Conan Doyle primarily credited Joseph Bell as being the source of inspiration for his character Sherlock Holmes, he also cited Henry Littlejohn as being a contributing influence. Henry Littlejohn, as a forensic expert involved in police investigations, appears to have been joined by Joseph Bell on several investigations; furthermore, Sir Henry taught Arthur Conan Doyle forensic medicine when Doyle was studying at the medical school of the University of Edinburgh.

Henry Littlejohn was knighted in 1895 by Queen Victoria.

In his later life he lived at 24 Royal Circus in Edinburgh's Second New Town.

He died at Benreoch, near Arrochar in Argyll in 1914, and was interred at the Dean Cemetery in Edinburgh. His grave is on the edge of the southern path towards the west end. He is buried with his wife, Isabella Jane Harvey, and their children.

Henry Harvey Littlejohn

Sir Henry was the father of Henry Harvey Littlejohn (1862-1927) (normally just called Harvey Littlejohn during his life but posthumously largely called Henry) who followed in his father's footsteps and continued his adoption of tangential thinking to resolve investigations. His early years were spent at the family home, then at 40 York Place.

H.H.Littlejohn adopted unusual methods of study. This included mapping instances of typhoid across Edinburgh in 1891 in conjunction with the noted map-maker, J. G. Bartholomew. The purpose of this was to track down the source of the outbreak. This technique is now common practice in police techniques to observe patterns in pursuit of crime detection.

The results, published in the Edinburgh Medical Journal in March 1891, proved the outbreak centred upon a property at Gardners Crescent, in the west of the city, with almost all neighbouring houses becoming infected. He then tracked the original source to a batch of milk from one individual farm, tracked down all the shops which he supplied, and had all milk destroyed (compensating the shop-owners).

In 1902 he was elected a Fellow of the Royal Society of Edinburgh. His proposers were Sir William Turner, Alexander Crum Brown, and Sir Thomas Richard Fraser.

He was one of the first persons in the world to be appointed as Chief Police Surgeon for a city (1906).

In later life Harvey lived at 1 Atholl Crescent in Edinburgh's West End.

He died at a nursing home in Edinburgh on 15 August 1927. Henry Harvey is buried in his father's plot at Dean Cemetery.
