Perfect for kids who are fascinated by insects and American history, here is the story of Nan Songer, a little-known hero of World War II, who collected and bred spiders in her home and found new ways to use their silk to help the United States win the war.
Venomous spiders, delicate silk, and science experiments filled Nan Songer’s days and nights—her home in California overflowed with many-legged critters. With inspiration from a friend, Nan began to study how spider silk could be harvested. The finely woven material spiders used to create webs was much stronger than it looked, and Nan was eager to unlock its potential and hopefully help her country at the same time. At the height of WWII, she studied different spiders before landing on the poisonous black widow as the perfect spider to experiment with. Their strong silk could be used for crosshairs on rifles, which Nan used to fill massive orders for the US military. Despite the danger posed by black widows, Nan wasn’t deterred—she wanted to play her part. Using a device she built for extracting silk, Nan humanely used it on the deadly spiders to get both extra fine and super heavy silk.
"A self-taught scientist rose to the challenge when World War II increased demand for spider silk. Klostermann’s brief, engrossing text eschews typical biographical information (Nan’s birthplace, education), focusing instead on her subject’s fascinating work. Lambelet’s meticulously detailed sepia and teal art vividly depicts Nan in pursuit of her passionate vocation. Weaves an impressive story of arachnid accomplishment."—Kirkus Reviews
"With a palette plucked from nature, this educational picture book spins the tale of an unsung hero of WWII."—Foreword Reviews
"The prospect of using spider silk for anything but weaving webs will fascinate young readers, and Songer's creative efforts to collect the silk with homemade contraptions will easily hold their attention... An intriguing snapshot of the intersection of human invention and the natural world, perfect for STEM collections."—Booklist
"Neither my son nor I had any idea that one could farm spiders for their silk, let alone that this silk could be useful for military operations, so this book piqued our attention. Songer's story turned out to be so unusual and fascinating that we were left wondering why it is not better known today... Gorgeous illustrations by Anne Lambelet are very helpful for conveying the natural beauty of various spider types as well as complicated concepts, such as the various devices Songer designed to farm her spiders, immobilize them, and safely extract their precious silk. Once my second grader started reading the book, he couldn't put it down and concluded that it was interesting and 'very cool.' This adult reviewer concurs and also couldn't help secretly wondering whether it might be fun to have some arachnid pets."—Science
