British physician Edward Jenner develops first-ever successful vaccine
In the West, Jenner is often called “the father of immunology”, and his work is said to have “saved more lives than the work of any other human”.
Public health & disease
From disease eradication efforts to advances in vaccination and maternal health, this archive tracks real progress in public health. Stories here focus on what’s working — policies, interventions, and research that are improving and extending lives around the world.
Hanaoka Seishū performs the first documented surgery under general anaesthesia
In October 1804, a Japanese surgeon named Hanaoka Seishū removed part of a 60-year-old woman’s breast while she slept peacefully under an herbal anesthetic he had spent two decades perfecting. His formula, tsūsensan, drew on Chinese pharmacology and Dutch medical texts. It stands as the first reliably documented surgery under general anesthesia, nearly four decades before ether.
William Cullen demonstrates the world’s first artificial refrigeration machine
Artificial refrigeration began in a Scottish laboratory in 1755, when physician William Cullen used a vacuum pump over a flask of ether to coax a thin crust of ice into existence. It had no practical use in his lifetime. But the principle he glimpsed — cold as a human act, not a gift of weather — would eventually reshape how and where people live.
Jacob Nufer performs the first recorded cesarean birth with both mother and baby surviving
Cesarean birth survival entered medical memory around 1500 C.E., when a Swiss pig gelder named Jacob Nufer reportedly opened his wife’s abdomen after days of failed labor — and both lived. The story, written down 82 years later by a surgeon with an agenda, may be embellished, but it gave European medicine something powerful: proof that survival was even imaginable.
Ibn Sina completes the Canon of Medicine, reshaping global healthcare
The Canon of Medicine was completed in 1025 C.E. by Ibn Sina, a physician working across Central Asia and Persia who pulled together Greek, Persian, Indian, and Chinese medical knowledge into one five-volume synthesis. Translated into Latin in 12th-century Toledo, it became a standard textbook in European universities for roughly seven centuries.
Ancient Greek physicians set the foundations of medical ethics
The Hippocratic Oath, written sometime in the fourth or fifth century B.C.E. by an unknown author in the Greek medical tradition, bound physicians to their patients through a code of care, confidentiality, and restraint. Though the famous phrase “first, do no harm” came later, the spirit endured — shaping how societies have thought about medical duty for roughly 2,500 years.
Chinese scholar records earliest known use of toilet paper
Toilet paper first appears in the historical record around 589 C.E., when Chinese scholar Yan Zhitui mentioned, almost in passing, that he wouldn’t use paper bearing sacred texts for hygiene. The offhand tone suggests the practice was already ordinary. A small line in a personal essay, quietly marking one of the longest arcs in everyday human comfort.
Sushruta Samhita becomes one of history’s most advanced medical texts
The Suśrutasaṃhitā, a Sanskrit medical compendium likely completed between 300 and 500 C.E., catalogs more than 300 surgical procedures and 120 instruments, including a rhinoplasty technique European surgeons would independently rediscover centuries later. Built by many hands across generations, it stands as one of the foundational works of Ayurveda.
The Edwin Smith Papyrus records the first known written cancer diagnosis
The Edwin Smith Papyrus, written around 2650 B.C.E., contains what historians recognize as the oldest known written diagnosis of cancer. In a surgical text methodically working through 48 cases, an Egyptian scribe described hard, cool tumors of the breast and offered an unflinching verdict: “There is none.” Naming a disease honestly, it turns out, is itself ancient medicine.
