Anthony Martin Halliday (19 August 1926 – 18 March 2008) was a British physician and consultant in clinical neurophysiology.
His family history included numerous ancestors working in the field of medicine.
His research was valuable as British pilots at times fell asleep while flying round the clock for the Berlin airlift.
As such, it was noticed by Arnold Carmichael, the director of the neurophysiology unit of the National Hospital.
With Ian McDonald he developed a technique which led to laboratory tests for the diagnosis of multiple sclerosis.
