222:, the idea that atomic weights are multiples of hydrogen. However, he remained more disposed than the Belgian chemist to consider the possibility that it may have some degree of validity. By establishing well-defined values for a wide variety of elements, he seriously contributed to the underlying basis of inorganic chemistry.

Marignac's name is well known for the careful and exact determinations of atomic weights. Whenever possible, he used at least two independent methods to assess a sample. He carried these out for long-identified elements and for newly proposed elements. In undertaking this work he had, like

On his return, Marignac became in 1841 a professor of chemistry at the
Academy of Geneva. In 1845 he was appointed professor of mineralogy as well. He held both chairs until 1878, when he resigned due to poor health. He was able to continue working in a laboratory at his house until 1884, when he
