Marvelous Mattie: How Margaret E. Knight Became an Inventor

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.

"Mattie's story is told in a style that is not only easy to understand, but that is also a good read-aloud. The watercolor-and-ink illustrations capture the spirited inventor and support the text in style and design. Their sketchy quality works well with the pen-and-ink drawings of inventions at the bottom of the pages. While most of these are simulated, the actual drawings from the 1871 patent for the paper-bag machine are included....An authors note gives additional biographical information about this creative woman." – Carolyn Janssen, School Library Journal
