From smallpox to sun lamps, the health of London and Londoners over 125 years is uncovered in over 5000 fully searchable reports, from 1848 to 1973, detailing the health of Londoners in intimate detail – borough by borough and often street by street - written by the people responsible for keeping the city healthy over a period of drastic social, economic and technological change. The reports also offer an unparalleled insight into Londoners’ lives. From weather reports to sanitary conditions, the MOHs covered a dizzying array of topics. They contain details of London’s lost trades, such as hair-merchants and pigeon-fatteners, provide reports on the conditions of child-workers in factories and families in slum housing, and trace Londoners’ changing tastes in fast-food from oysters to Chinese takeaways. The digitised pages allow for data mining, close reading, embedding and free downloading of all pages from the reports.
