Archival Overview

Renowned Norwegian physician who discovered the bacterium Mycobacterium leprae in 1873, identifying leprosy as an infectious disease rather than a hereditary curse.

Biographical Record

Gerhard Henrik Armauer Hansen was born on July 29, 1841, in Bergen. After medical studies at the Royal Frederick University in Christiania, he joined the staff of the Pleiestiftelsen for Spedalske (Leprosy Hospital) in Bergen in 1868 under Daniel Cornelius Danielssen.

Hansen challenged the prevailing consensus that leprosy was hereditary or caused by miasmas. In 1873, through meticulous microscopic examination of unstained skin nodules, he observed rod-shaped microorganisms—becoming the first scientist to identify a specific bacterium as the cause of a chronic human disease. His isolation laws and hygiene measures drastically reduced leprosy in Norway and inspired modern global eradication efforts.
