The Lancet 1823-2023: the best science for better lives

The Lancet celebrates its 200th anniversary in 2023. In this survey of the journal's history, we explore how it has contributed to shaping medicine both in the UK and internationally, and how it has demonstrated a commitment to "The best science for better lives". For two centuries, the journal has published pioneering articles on key developments in medical science and the organisation of health care. We explore the campaigning and advocacy work of the journal through several indicative areas where science and policy meet, balancing national and global themes over the 19th and 20th centuries. Themes include the raising of professional standards; environmental health in urbanising Britain; the transformation of surgery; the emergence of tropical medicine; the science and politics of vaccination; the advance towards universal health coverage; and the transition from international to global health. In the imperial era, both the journal's research reports and editorial stance were sometimes inflected with colonial attitudes, although it consistently presented medicine as an international endeavour. The Lancet's blend of science and advocacy demonstrates a track record of campaigning for medicine in the cause of social betterment.
