# Pediatrician
## Overview
A **pediatrician** is a physician who specializes in the medical care of infants, children, and adolescents. The specialty encompasses preventive care (vaccinations, developmental screening), acute illness management, and chronic disease treatment for patients from birth through age 18.
## Etymology
From **pediatrics** + **-ian** (agent suffix). *Pediatrics* was coined in 1884 from Greek *pais* (genitive *paidos*, 'child') and *iatrikos* ('of healing'), from *iatros* ('healer, physician'), from *iasthai* ('to heal'). The Greek healing root traces to PIE **\*yeh₂-** ('to be vigorous, to cure').
Greek *iatros* ('healer') and *iatreia* ('healing, medical treatment') combine with various prefixes to name medical specialties:
- **Pediatrics**: *pais/paidos* ('child') + *iatreia* — child medicine - **Psychiatry**: *psychē* ('soul, mind') + *iatreia* — mind-healing - **Geriatrics**: *geras* ('old age') + *iatreia* — old-age medicine - **Podiatry**: *pous/podos* ('foot') + *iatreia* — foot medicine - **Iatric**: relating to medicine or physicians generally - **Iatrogenic**: *iatros* + *-genēs* ('born from') — caused by medical treatment itself
The distinction between **pediatrics** (*paidos*, 'child') and **podiatry** (*podos*, 'foot') is a common source of confusion, as the English forms sound similar. The Greek roots are entirely different.
## Historical Development
Before pediatrics emerged as a distinct specialty, children were treated by general practitioners using adult medical models. Dosages were scaled down roughly by size, children's developmental differences were poorly understood, and many childhood diseases were not recognized as distinct from their adult equivalents.
Key milestones:
- **1745**: The Foundling Hospital in London began providing dedicated medical care for children - **1802**: Hôpital des Enfants Malades (Hospital for Sick Children) opened in Paris — the first pediatric hospital - **1852**: The Hospital for Sick Children (Great Ormond Street) opened in London - **1860**: Abraham Jacobi established the first children's clinic in the US at New York Medical College - **1884**: The term 'pediatrics' was coined - **1930**: The American Academy of Pediatrics was founded
Jacobi, a German-born physician who emigrated to the United States, argued that children were not merely small adults but physiologically distinct organisms requiring specialized medical knowledge. This insight — now obvious — was revolutionary in its time.
## British vs. American Spelling
British English spells it **paediatrics** and **paediatrician**, preserving the Greek diphthong *ai* from *paidos*. American English simplified the spelling to **pediatrics** in the 19th century, dropping the *a*. Both spellings are correct in their respective conventions.
## Related Forms
The family includes **pediatrics** (the specialty), **pediatric** (adjective), **pediatrician** (American) / **paediatrician** (British), and **neonatology** (the sub-specialty focused on newborns — from Greek *neos* 'new' + Latin *natus* 'born').
