Francis John Worsley Roughton FRS (6 June 1899 – 26 April 1972) was an English physiologist and biochemist.
Along with Hamilton Hartridge, he developed continuous monitoring approaches to study liquid-gas binding reactions and enzyme kinetics.
At Cambridge he decided not to follow the family line and began to study physiology after being influenced by Joseph Barcroft.
Another student of Barcroft, Hamilton Hartridge, developed an experimental apparatus consisting of a mixing chamber for two liquids where inflows and outflows could be controlled and studied.
[5] In 1927 Roughton became lecturer in physiology and he moved on to the study of chemical kinetics involved in haemoglobin binding.
