Waksman would win the Nobel Prize in Physiology or Medicine in 1952 for his discoveries in antibiotics. Corwin Hinshaw and William Feldman took the streptomycin samples and cured tuberculosis in four guinea pigs with it. Hinshaw followed these studies with human trials that provided a dramatic advance in the ability to stop and reverse the progression of tuberculosis.[21][22] Mortality from tuberculosis in the UK has diminished from the early 20th century due to better hygiene and improved living standards, but from the moment antibiotics were introduced, the fall became steep so that by the 1980s mortality in developed countries was effectively zero.[23]
