With her sketchbook labeled "My Inventions and her father's

toolbox, Mattie could make almost anything - toys, sleds, and

a foot warmer. When she was just twelve years old, Mattie

designed a metal guard to prevent shuttles from shooting off

textile looms and injuring workers. As an adult, Mattie

invented the machine that makes the square-bottom paper

bags we still use today. However, in court, a man claimed the

invention was his, stating that she "could not possibly

understand the mechanical complexities." Marvelous Mattie

proved him wrong, and over the course of her life earned the

title of "the Lady Edison." With charming pen-and-ink and watercolor illustrations, this

introduction to one of the most prolific female inventors will

leave readers inspired.
