LEAD – LEssons from the pAst is a digital platform and data hub for forgotten empirical knowledge about Swiss health history over the last 150 years.

LEAD is based on previously inaccessible historical archive and library sources containing demographic and epidemiological data from the 19th and 20th centuries. The thematic focus is on pandemics and epidemics, infectious diseases and mortality patterns.
