The British author who harvested mutant, jumbo peanuts from her atomic garden
In 1948, Muriel Howorth was living a relatively ordinary life in the seaside town of Eastbourne on the south coast of England when she received a letter that would completely change the trajectory of her life.
From an early age, she had wanted to take part, or as she put it, “be of use” in international affairs. During World War II, she was employed by the Ministry of Information, the government office primarily responsible for wartime publicity and propaganda in the UK.
Howorth must have been talented at promotion and publicity, because the letter that arrived in 1948—“out of the blue,” according to her personal papers—inquired if she would like to apply her talents to making atomic energy seem more friendly.
She was well-educated, but not terribly knowledgeable about atomic science, so she borrowed a book by the radiochemist Frederick Soddy, who was born in Eastbourne, titled The Interpretation of Radium. Within a few chapters, she found herself a true believer in the promise of the atom. She would devote the rest of her life to sharing the wonders of atomic science with anyone who would listen.
Nuclear energy gets a rebrand after WWII
The United States dropped atomic bombs on the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, a key factor in the end of World War II. The scale of the destruction and the ongoing damage from nuclear fallout after these attacks was vast. Despite the devastation, when a Gallup poll was released in mid-August of 1945, 85 percent of Americans approved of the bombing.
The atom was more or less a mystery to the average American, and was seen both as something to be feared and a source of hope. The potential for nuclear energy seemed endless, and although the Soviet Union was America’s ally, establishing a lead over the Soviets in nuclear technology seemed prudent.
Muriel Howorth’s pro-nuclear children’s book and atomic gardening
In the years after World War II, American and European scientists and heads of state agreed that there should be a focus on more productive and peaceful uses for atomic power. The letter that Howorth received in 1948 was part of this effort. She threw herself into projects that combined science education and entertainment.
Notable among these was an elaborately choreographed pantomime titled Isotopia: An Exposition on Atomic Structure. Howorth also self-published a children’s book featuring Daddy Proton, Mummy Neutron, and their electron children. Her greatest impact as an early science communicator, though, was her work in atomic gardening.
Irradiated peanuts and other miracles of atomic gardens
Applying radiation to agricultural plants was, in part, a response to wartime scarcity. Restricted rations had made people acutely aware of the possibility of food insecurity. Researchers hoped that exposure to gamma radiation might induce mutations that resulted in higher-yielding or disease-resistant crop varieties. Perhaps some of those crops might be more dense in nutrients, too.
As atomic ambassador, Howorth founded the Atomic Gardening Association and recruited hundreds of members—or, as she called them, “atomic mutation experimenters.” Soon, atomic gardening kits were available to the public. One could send away for packets of seeds from an irradiated plant. By planting these seeds and propagating multiple generations of the plants, home gardeners could test whether any useful-seeming mutations had arisen.
Howorth herself served a mutated variety of Carolina peanuts to some of her scientist friends in 1959. Their response was underwhelming, so she planted the rest of the peanuts in her garden, where they grew remarkably quickly and produced extremely large peanuts. She usually kept a handful of these extra-large peanuts tucked away in her handbag in case the opportunity arose to recruit a new member to the Atomic Gardening Association.
Howorth’s lasting legacy to citizen science
It’s tempting to view Howorth as a kooky eccentric. Contemporary newspaper reports of her various events and projects were certainly dismissive in tone. More accurately, she represents an early effort at addressing the gap between scientific research and public understanding.
The world was far less interconnected in her day, with no internet, no omnipresent news media, and no social media platforms. Not only that, but the idea of women as integral parts of scientific research was slow to catch on, despite pioneering work by scientists like Marie Curie and Rosalind Franklin.
Today, the same gulf exists between what scientists publish in their fields and what the average person understands. The same challenge of translating scientific language for public consumption exists for science communicators, but the tools available to them have evolved beyond recognition. You can find videos and posts by scientists explaining everything from how blimps work to what various chemical reactions look like, or from how fossils form to why black holes are so dark.
If Howorth were around today, her atomic choreography might have gone viral. As it stands, she was a wonderful example of the love of sharing knowledge with the public, and of the excitement and joy that comes with learning new things about how our world works.
