The Paper Bag Machine Genius: Margaret Knight

By Michael Webster

We use it every day, but few know its story. The flat-bottomed paper bag, a simple and indispensable part of modern life, was the revolutionary invention of Margaret E. Knight.

Born in a 19th-century mill town, Knight was a mechanical prodigy who defied a world that believed a woman's place was not in the workshop. This book tells the gripping story of her most famous invention and the landmark legal battle that followed when a man tried to steal her genius, claiming a machine so complex could not have been created by a woman.

The Invisible Genius is a powerful account of perseverance, intellectual property, and a quiet revolutionary who built a better world, one invention at a time. Approx.160 pages, 28000 word count
