Barry Commoner (1917–2012) was an American cellular biologist who became one of the earliest and most public figures of the modern environmental movement. His research on radioactive fallout, gathered through the St. Louis Baby Tooth Survey, helped bring about the 1963 Partial Nuclear Test Ban Treaty, and his 1971 book The Closing Circle introduced a wide readership to the idea that human and natural systems are bound together. Time put him on its cover in 1970 as "the Paul Revere of Ecology" (NPR).
Barry Commoner was born on 28 May 1917 in Brooklyn, New York, to Russian Jewish immigrants (Wikipedia). He studied zoology at Columbia University, graduating in 1937, then continued at Harvard, where he earned a master's degree in 1938 and a doctorate in 1941. During the Second World War he served as a lieutenant in the US Navy. In 1947 he joined Washington University in St. Louis as a professor of plant physiology, a post he held for more than three decades until 1981 (WashU). His laboratory work on the biochemistry of living cells shaped how he later described the environment, as a web of connected systems rather than a set of separate parts.
In the late 1950s Commoner turned his attention to nuclear fallout. Working through the Greater St. Louis Citizens' Committee for Nuclear Information, he helped launch the Baby Tooth Survey in 1958, in which parents mailed their children's shed teeth for analysis (St. Louis Magazine). The study found that children born in the early 1960s carried far more radioactive strontium-90 in their teeth than those born before large-scale atmospheric testing. The findings reached President John F. Kennedy and added public weight to the 1963 Partial Nuclear Test Ban Treaty, which halted above-ground testing by the United States, United Kingdom, and Soviet Union (Baby Tooth Survey).
Commoner founded the Center for the Biology of Natural Systems at Washington University in 1966 to study the links between organisms and their surroundings. His 1971 book The Closing Circle set out four plain statements he called the laws of ecology: everything is connected to everything else; everything must go somewhere; nature knows best; and there is no such thing as a free lunch (Wikipedia). He argued that postwar industrial technology was the main driver of pollution, a position that put him at odds with the biologist Paul Ehrlich, who stressed population as the central problem.
His politics grew from that argument. Commoner held that ecological harm was tied to social and economic inequality, and he described himself as a socialist. In 1980 he ran for president as the candidate of the Citizens Party, with LaDonna Harris as his running mate; the ticket won 233,052 votes, about a quarter of one percent of the total, but carried environmental questions into a national campaign. When he left Washington University in 1981, he moved the center to Queens College in New York, directing it until 2000 (Wikipedia).
Commoner is often called a founder of modern ecology (WashU). His four laws remain a short, memorable way to teach how ecosystems respond to interference, and the Baby Tooth Survey is an early case of ordinary citizens gathering scientific data to change public policy. He was also an early voice for what became known as environmental justice, arguing that pollution falls hardest on poor and marginalized communities. He kept writing and campaigning into his nineties and died in Manhattan on 30 September 2012, at the age of 95.
Commoner is easy to flatten into a single slogan about connection. Confinity keeps the fuller record, the laboratory science, the fallout study, the books, and the campaigns, so the reasoning behind the slogans stays legible to anyone who reads on.
