History of medicine
The study of how medical knowledge, practices, institutions, and technologies have changed across time and cultures.
Edwin Smith Papyrus: An ancient Egyptian surgical treatise describing injuries, examinations, diagnoses, and treatments. Its case-based approach offers an early record of practical medicine.
Anatomical dissection: The examination of a body's internal structures by cutting and separating tissues. Dissection challenged inherited anatomical claims through direct observation.
Hippocrates: An ancient Greek physician traditionally regarded as a foundational figure in Western medicine. His name became attached to a professional ideal of observation and ethical conduct.
Smallpox vaccine: A vaccine that protects against smallpox, developed from observations of cross-protection by cowpox. Vaccination enabled the first disease eradicated worldwide.
Humoral theory: An ancient and medieval theory that health depended on the balance of four bodily fluids. Its decline contrasts with explanations based on anatomy, pathology, and experiment.
Hippocratic Corpus: A collection of ancient Greek medical writings associated with Hippocrates and his followers. These texts helped shape later accounts of disease, prognosis, and medical ethics.
Germ theory of disease: The theory that microorganisms cause many infectious diseases. It redirected prevention and treatment toward specific infectious agents.
Avicenna: A Persian polymath whose medical encyclopedia, The Canon of Medicine, influenced learning across regions. His synthesis transmitted and organized medical knowledge for later institutions.
Public health: The organized effort to protect and improve the health of populations. Medicine increasingly acted through sanitation, prevention, and policy beyond individual treatment.
Miasma theory: The theory that diseases such as cholera spread through poisonous or unhealthy air. Its displacement by germ theory changed strategies for controlling epidemics.
