William Guy FRSE FRCS BDA FDS LLD (1859-1950) was a British pioneer of modern dentistry and the widespread use of anaesthesia.
The final 5 years (1935-1939) were in a transition period with Arthur Cyril William Hutchison, who eventually replaced him fully in 1939.
From October 1899 (prior to its customary use in clinical surgery) he was the first person to employ permanent anaesthetists in the UK.

His proposers included William Spiers Bruce and Thomas Smith Clouston.
