william budd -lrb- 14 september 1811 -- 9 january 1880 -rrb- was an english physician and epidemiologist known for recognizing that infectious diseases were contagious .
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 -lrb- as he learned from the work of the physician john snow -rrb- and typhoid fever .
