RIP Donella Meadows (1941-2001), a founder of the sustainability movement in environmental thinking and lead author of the seminal ecological tract, The Limits to Growth (1972). Trained as a chemist and biophysicist, she taught global trend analysis and system dynamics at Dartmouth and was no stranger to information science; the Limits to Growth project was in no small part a computer modelling effort. She was a recipient of a MacArthur ‘genius grant’ for her work, and participated in an international group of scientists which “built early and critical avenues of exchange between scientists on both sides of the Iron Curtain at the height of the Cold War.”
