Dominique-Jean Larrey established an ambulance service in 1792.
Edward Jenner pioneered vaccination against smallpox in 1796 using cowpox material.

Medicine in the 19th Century

Early views posited spontaneous generation and internal imbalances caused diseases.
Rapid advancements with the introduction of anesthesia and antiseptic techniques.
Public health improvements significantly reduced lethal diseases more than medical advances.
René Laennec invented the stethoscope to improve diagnosis of lung diseases in 1816.
John Snow linked cholera outbreaks to contaminated water, catalyzing the germ theory of disease.
Ignaz Semmelweis promoted hand disinfection in obstetrics, reducing puerperal fever rates.
Louis Pasteur established bacteriology through his experiments on fermentation and disease causation.
Vaccine development during this period included vaccine creation for anthrax and rabies by Pasteur.
Anesthesia revolutionized surgery, with significant advancements such as ether use in 1846.
Joseph Lister advanced antiseptic methods significantly, improving surgical outcomes.

Medicine in the 20th Century
