Chester Carlson’s Spark

from Let's Rewind! - Heroes Who Changed Everything - Little Thinkers!

Meet Chester Carlson: a quiet inventor whose kitchen experiments turned light and dust into the copier we know today! This warm, true story is perfect for curious minds aged 7-13: long nights, small rooms, careful experiments and a simple first paper that changed offices forever. Follow the moment a glass plate, a sweep of light, and powdered toner made a clear page appear — a tiny miracle of science and patience. Historical Fun Fact: The very first dry copy carried the handwritten date Ten Twenty Two 1938 and was made in a rented room in Astoria, Queens. Did you know? Xerography comes from Greek words meaning dry writing, and Chester called his first method electrophotography before the name changed! Ben & Pia guide this gentle, inspiring adventure with warm storytelling and curiosity.
