William Prout (1785–1850) was an English chemist and physician known for his contributions to the field of chemistry, particularly in the study of atomic theory. He is best known for Prout's hypothesis, which suggested that all atomic weights are whole-number multiples of the weight of the hydrogen atom, proposing hydrogen as the fundamental building block of all matter.
