1776-1844. British chemist, the first in
modern times to propose the existence of
atoms, which he considered to be the
smallest parts of matter. He produced the
first list of relative atomic masses,
Absorption of Gases 1805. He was also the
first scientist to note and record
colour-blindness. From experiments with
gases he noted that the proportions of two
components combining to form another gas
were always constant. From this he suggested
that if substances combine in simple
numerical ratios then the macroscopic weight
proportions represent the relative atomic
masses of those substances.
