Marvelous Mattie: How Margaret E. Knight Became an Inventor  (F,S&G, 2006)

by Emily Arnold McCully

Overview

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.”
