Barry Commoner (May 28, 1917 – September 30, 2012) was an American cellular biologist, college professor, and politician. He was a leading ecologist and among the founders of the modern environmental movement. He was the director of the Center for Biology of Natural Systems and its Critical Genetics Project. He ran as the Citizens Party candidate in the 1980 U.S. presidential election. His work studying the radioactive fallout from nuclear weapons testing led to the Nuclear Test Ban Treaty of 1963. Early life Commoner was born in Brooklyn, New York, on May 28, 1917, the son of Jewish immigrants from Russia. He received his bachelor's degree in zoology from Columbia University in 1937 and his master's and doctoral degrees from Harvard University in 1938 and 1941, respectively. Career in academia After serving as a lieutenant in the US Navy during World War II, Commoner moved to St. Louis, Missouri, and he became an associate editor for Science Illustrated from 1946 to 1947. He became a professor of plant physiology at Washington University in St. Louis in 1947 and taught there for 34 years. During this period, in 1966, he founded the Center for the Biology of Natural Systems to study "the science of the total environment". Commoner was on the founding editorial board of the Journal of Theoretical Biology in 1961. In the late 1950s, Commoner became known for his opposition to nuclear weapons testing, becoming part of the team which conducted the Baby Tooth Survey, demonstrating the presence of Strontium 90 in children's teeth as a direct result of nuclear fallout. In 1958, he helped found the Greater St. Louis Committee on Nuclear Information. Shortly thereafter, he established Nuclear Information, a mimeographed newsletter published in his office, which later went on to become Environment magazine. Commoner went on to write several books about the negative ecological effects of atmospheric (i.e., above-ground) nuclear testing. In 1970, he received the International Humanist Award from the International Humanist and Ethical Union. Environmental books The Closing Circle In his 1971 bestselling book The Closing Circle, Commoner suggested that the US economy should be restructured to conform to the unbending laws of ecology. For example, he argued that polluting products (like detergents or synthetic textiles) should be replaced with natural products (like soap or cotton and wool). This book was one of the first to bring the idea of sustainability to a mass audience.
