Christian René, viscount de Duve (2 October 1917 - 4 May 2013) was a Nobel Prize-winning cytologist and biochemist. De Duve was born in Thames Ditton, Surrey, Great Britain, as a son of Belgian refugees. They returned to Belgium in 1920. De Duve was educated by the Jesuits at Onze-Lieve-Vrouwecollege in Antwerp, before studying at the Catholic University of Leuven, where he became a professor in 1947. He specialized in subcellular biochemistry and cell biology and discovered peroxisomes and lysosomes, cell organelles. De Duve chose to end his life through legal euthanasia.
In 1962 de Duve joined the faculty of what is now Rockefeller University in New York City, dividing his time between New York and Leuven. He took emeritus status at Université catholique de Louvain in 1985 and at Rockefeller in 1988, though he continued to conduct research. Among other subjects, de Duve studied the distribution of enzymes in rat liver cells using rate-zonal centrifugation. De Duve's work on cell fractionation provided an insight into the function of cell structures.
In 1960, de Duve was awarded the Francqui Prize for Biological and Medical Sciences. He was awarded the shared Nobel Prize for Physiology or Medicine in 1974, together with Albert Claude and George E. Palade, for describing the structure and function of organelles (lysosomes and peroxisomes) in biological cells. His later years have been mostly devoted to origin of life studies, which he admits is still a speculative field (see thioester).
His work has contributed to the emerging consensus that the endosymbiotic theory is correct; this idea proposes that mitochondria, chloroplasts, and perhaps other organelles of eukaryotic cells originated as prokaryote endosymbionts, which came to live inside eukaryotic cells.
De Duve proposed that peroxisomes may have been the first endosymbionts, which allowed cells to withstand the growing amounts of free molecular oxygen in the Earth's atmosphere. Since peroxisomes have no DNA of their own, this proposal has much less evidence than the similar claims for mitochondria and chloroplasts.
De Duve died May 4, 2013, at his home in Nethen, Belgium. He decided to end his life by legal euthanasia. He had been suffering from cancer and atrial fibrillation, and his health problems were exacerbated by a recent fall in his home. He was 95. De Duve is survived by two sons, Thierry and Alain; two daughters, Anne and Francoise; two brothers, Pierre and Daniel; seven grandchildren; and two great-grandchildren.
