George Warwick Bampfylde Daniell (1864–1937) was medical practitioner and anaesthesiologist who practised in South Africa in the 19th and 20th centuries.
Daniell wrote a number of papers on the health benefits of the mineral waters there: He recommended both drinking and bathing in the hot mineral water, which he considered beneficial for anemia, rheumatism, gout, neuralgia, chronic diarrhoea, skin diseases, and many other complaints.
He used several agents in addition to ether and chloroform, such as ethyl chloride and a mixture of nitrous oxide and oxygen.
Some of his early modifications of apparatus and original designs were displayed in the anaesthetics Museum of the British Medical Association in 1910.
