Origins
The word 'ambulance' preserves a now-inverted history.βββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββββ It originally named a hospital that walked β a mobile surgical unit that moved toward the wounded β before it became the vehicle that carries the wounded toward a fixed hospital. This reversal encodes a significant shift in medical strategy over two centuries.
The term was coined during the Revolutionary and Napoleonic Wars. Dominique Jean Larrey (1766β1842), Napoleon's chief surgeon and one of the most innovative military physicians of any era, observed that wounded soldiers left on the battlefield for hours or days β the standard practice, since surgeons operated only after engagements ended β were dying of injuries that prompt care could have treated. He proposed bringing the surgeons to the soldiers. His solution was the 'ambulance volante' (flying ambulance): a specially designed horse-drawn carriage equipped with surgical instruments and driven directly behind the lines, collecting and treating wounded men while the battle was still in progress. The 'ambulance' was the whole rolling institution β surgeons, orderlies, equipment β not merely the wagon.
The French word 'ambulance' was derived from the phrase 'hΓ΄pital ambulant' (walking hospital), from the Latin participial stem 'ambulant-' (going, walking), from 'ambulΔre' (to walk, to go about). Latin 'ambulΔre' is of uncertain but probably Indo-European ancestry, connected to PIE roots meaning to go or wander. Related Latin words include 'ambΔ«re' (to go around) and the productive suffix '-ambulate.' The English word 'amble' comes from Old French 'ambler,' from the same Latin root, originally describing the easy gait of a horse. 'Perambulate' (to walk through or about) and 'preamble' (that which walks before, an introduction) share the root.
Development
English borrowed 'ambulance' during the Napoleonic period, initially in the military sense of a mobile field hospital. The word entered civilian use gradually through the nineteenth century. As cities grew and hospitals multiplied, the need arose for vehicles to transport patients to fixed facilities. The horse-drawn ambulance wagon appeared in New York City in 1869 at Bellevue Hospital β the first civilian ambulance service in the United States. By this time, 'ambulance' had shifted from naming the whole mobile hospital to naming just the conveyance.
The word 'ambulatory' (relating to walking; able to walk; also, an outpatient clinic) shares the root and retains a ghost of the original concept: ambulatory care is care that walks β care that does not require admission to a fixed bed. 'Somnambulism' (sleepwalking) combines 'somnus' (sleep) with 'ambulΔre.' The covered walkway of a cloister β the 'ambulatory' β was so called because monks walked there in procession.
Larrey's invention was so admired that the Duke of Wellington, his enemy at Waterloo, ordered British guns not to fire on Larrey's ambulances. The humanitarian impulse at the root of the word has not changed, even if the direction of travel has reversed.
