Biography

James Lind was a Scottish naval surgeon who conducted the first controlled clinical trial in 1747, systematically testing treatments for scurvy aboard HMS Salisbury. His groundbreaking discovery that citrus fruits prevented the disease revolutionized maritime medicine and saved countless sailors' lives, establishing the foundation for modern evidencebased medicine.

Key Facts

Conducted the first randomized controlled experiment in medical history, testing six different scurvy treatments on 12 sailors under identical conditions
Served as surgeon on various naval vessels, witnessing scurvy kill more sailors than combat during the Age of Exploration
Published 'A Treatise of the Scurvy' in 1753, documenting his findings and advocating for citrus juice rations in the Royal Navy
It took 40+ years for the British Navy to officially adopt lemon juice rations fleet-wide, despite his conclusive evidence
His methodological approach to testing treatments—isolating variables and using control groups—became the blueprint for modern clinical trials

One sailor's radical idea: compare treatments fairly. Changed medicine forever.
