In 1847, 20 years before germ theory was popularised by Louis Pasteur, the Hungarian physician Ignaz Semmelweis famously reduced maternal mortality from post-partum sepsis from 16 to 1% simply by encouraging hand hygiene among his peers [ 1 ].

Aged just 47, he suffered a nervous breakdown, was committed to an asylum and died within 2 weeks, ironically and tragically, from a gangrenous wound.
