“If people would think more of fairies, they would soon forget the atom bomb,” Walt Disney quipped in 1948. President Dwight D. Eisenhower agreed: public fear of the atom bomb was growing, and in 1953 he assured Americans in his “Atoms for Peace” speech that war was not imminent and that nuclear technology had enormous potential for peacetime activity as well. Eisenhower then recruited Disney to produce a television program promoting the “peaceful atom.” In 1957, “Our Friend the Atom” aired on ABC, featuring animated cartoons and narration by Heinz Haber, a scientist who had worked in Nazi Germany and later became a technical consultant for Disney’s Tomorrowland theme park.

Amphetamine salts became popular among soldiers during World War II as a stimulant to counteract fatigue. One study estimates that up to sixteen million Americans had been exposed to Benzedrine by the end of the war. Civilian use increased rapidly after that, especially among upper-middle-class women, who used the drug for appetite suppression and as an antidepressant. In 1962 the pharmaceutical company Smith, Kline & French ran an advertisement targeted toward physicians and featuring a photograph of a female patient. “With your encouragement and Dexedrine Spansule,” the ad proclaims, “she’s losing weight.”

Muscle Shoals, Alabama, site of a huge munitions plant during World War II, had a surplus of ammonium nitrate in 1946. The U.S. Department of Agriculture suggested that the chemical, a primary ingredient in explosives, be used as fertilizer. Industrial production of the resulting synthetic fertilizer led to an explosion in corn yields in the 1950s. A Tennessee Valley Authority representative recounted that “as soon as the need for nitrate explosives fell off, we were ready to convert that to agricultural nitrate.” “We are eating the leftovers of the Second World War,” the environmental activist Vandana Shiva said in a 2005 speech.
