Henry Lewis Halliday (29 November 1945 – 12 November 2022) was a British-Irish paediatrician and neonatologist. In 2021, Halliday was awarded the James Spence Medal for research into neonatology, for coordinating two of the largest neonatal multicentre trials for prevention and treatment of a number of neonatal respiratory illnesses and for a breakthrough in the development of a new lung surfactant that brought relief to very small babies suffering from infant respiratory distress syndrome (RDS).
