On This Day in Medical History
On This Day (OTD) in medical history is LITFL’s day-by-day index of key milestones: landmark publications, pivotal procedures, major public health moments, and the people behind eponymous syndromes and signs. Each date links to a curated timeline designed to be quick to scan, easy to cite, and simple to expand as new sources are verified.
Use the dropdowns to jump straight to a specific day, or browse the month tables below. Wherever dates are debated (event vs publication vs presentation), we aim to label what the date actually represents and point you to the best available references in “Further reading”.
