The Woman Who Made Science Beautiful

Andrea Wulf:

It was silkworms that first captured 13–year–old Maria Sibylla Merian’s attention. She would later graduate to a wider set of creatures, watching caterpillars, pupae, butterflies, and moths for days, weeks, and months. Paintbrush in hand, Merian recorded each stage of their life cycles, noting every change and movement. She depicted the silkworm moth from eggs, hatching larvae, molts, cocoons, all the way to adult moths. She distinguished between male and female, and showed a silkworm feeding on a mulberry leaf. Unlike many other girls her age, Merian was not disgusted by hairy crawling creatures or by tightly cocooned ‘date pits’ as she called the chrysalis. She pocked, squeezed, and prodded them to note how they ‘roll up,’ ‘twist and turn violently,’ or ‘lie there as if dead.’
