  4. Theodore William Richards (born Jan. 31, 1868, Germantown, Pa., U.S.—died April 2, 1928, Cambridge, Mass.) was an American chemist whose accurate determination of the atomic weights of approximately 25 elements indicated the existence of isotopes and earned him the 1914 Nobel Prize for Chemistry.

  6. Theodore William Richards (1868–1928), the first American to be awarded the Nobel Prize in Chemistry, received it for the year 1914 for his accurate determinations of the atomic weights of a large number of chemical elements—25 in all, including those used to determine virtually all other atomic weights.

  7. Theodore William Richards (1868–1928) was born about one year before the periodic table emerged (Figure 1).[5–9] By then, reliable atomic weights of modest accuracy had been obtained for around 60 elements. Richards (Figure 2) was destined to redetermine the atomic weights for about 25 of those elements and train others who redid most of ...
