Sophus Mads Jørgensen

Sophus Mads Jørgensen was a Danish chemist. He is considered one of the founders of coordination chemistry, mainly by being one of the pioneers of chain theory, and is known for the debates which he had with Alfred Werner during 1893–1899. While Jørgensen's theories on coordination chemistry were ultimately proven to be incorrect, his experimental work provided much of the basis for Werner's theories. Jørgensen also made major contributions to the chemistry of platinum and rhodium compounds.
