He was born at North Tawton, Devon, on 23 February 1808, the third son of Samuel Budd, a surgeon there, and with six brothers entered the medical profession.
[1][2] Budd pursued medical studies in Paris and at the Middlesex Hospital, London, and was elected a Fellow of the Royal Society in 1836.
Here with George Busk he researched cholera, scurvy, and the pathology of the stomach and liver.
[1] Budd first came to notice by writing on the stethoscope as an acoustic instrument (Medical Gazette, 1837).
His report on cases of cholera in the Dreadnought during 1837, written with Busk, and his statistical account of cases collected from the records of the same hospital in the epidemic of 1832, were also standard works, summarised in "Cholera", which Budd contributed to Alexander Tweedie's Library of Practical Medicine, vol.
