Nicholas Georgescu-Roegen

Nicholas Georgescu-Roegen (born Nicolae Georgescu, 4 February 1906 – 30 October 1994) was a Romanian mathematician, statistician and economist. He is best known today for his 1971 magnum opus The Entropy Law and the Economic Process, in which he argued that all natural resources are irreversibly degraded when put to use in economic activity. A progenitor and a paradigm founder in economics, Georgescu-Roegen's work was decisive for the establishing of ecological economics as an independent academic sub-discipline in economics.

In the history of economic thought, Georgescu-Roegen was the first economist of some standing to theorise on the premise that all of earth's mineral resources will eventually be exhausted at some indeterminate future point. Early in his life, Georgescu-Roegen was the student and protégé of Joseph Schumpeter, who taught that irreversible evolutionary change and 'creative destruction' are inherent to capitalism. Taken together, by the 2010s Georgescu-Roegen had educated, influenced and inspired at least three generations of people, including his contemporary peers, younger ecological economists, still younger degrowth organisers and activists, and others throughout the world.

Several economists have hailed Georgescu-Roegen as a man who lived well ahead of his time, and some historians of economic thought have proclaimed the ingenuity of his work. In spite of such appreciation, Georgescu-Roegen was never awarded the Nobel Prize in Economics, although benefactors from his native Romania were lobbying for it on his behalf.
