He graduated from the University of Edinburgh in 1838.
He recognized that the "poisons" involved in infectious diseases multiplied in the intestines of the sick, were present in their excretions, and could then be transmitted to the healthy through their consumption of contaminated water. He particularly understood this about the transmission of cholera (as he learned from the work of the physician John Snow) and typhoid fever. In 1841 Budd moved to Bristol, where he started a practice and became part of the city"s health department.
Using his theory and reading John Snow"s essay about cholera in London (1849), he took measures to protect the Bristol"s water supply.
He is credited with decreasing the incidence of deaths from epidemics of cholera from 2000 (out of a population of 140,000) in 1849 to 29 in 1866. The medical and scientific communities did not identify the role of microorganisms in infectious disease until the work of Louis Pasteur.
His obituary is found in the Lancet 1880;i: 148.
