Stretton. Claude was known to be a bit of an eccentric and had close friendship with painters, including Diego Rivera and Paul Delvaux, and musicians such as Edgard Varèse. After his retirement in 1971 from the Université libre de Bruxelles and from the directorship of the Institut Jules Bordet, he continued his research at the University of Louvain with his collaborator Dr. Emil Mrena, who ended up resigning in 1977 due to decreasing activity of the Laboratory, moving to other research works. It is said that he continued his research in seclusion until he died of natural causes, at his home in Brussels, on Sunday night on 22 May 1983, but he had stopped visiting his own laboratory in Louvain already in 1976 due to his weak health.
