Tundra's Great Idea Series are early-reader biographies. The third book in the series introduces the fascinating Margaret Knight. Known as Mattie, she was different from most American girls living in 1850. She loved to make things with wood and made the best kites and sleds in town. Her father died when she was only three and by the time she was twelve she was working at the local cotton mill, alongside her two older brothers. One day she saw a worker get injured by a shuttle which had come loose from the giant loom, and the accident inspired her to invent a stop-motion device. It was to be the first of her many inventions. Margaret devoted her life to inventing, and is best known for the clever, practical, paper bag. When she died in 1914 she had ninety inventions to her name and over twenty patents, astounding accomplishments for a woman of her day. Monica Kulling deftly uses easy-to-read language and lots of dialogue to bring an amazing, inspiring woman to life. Color illustrations throughout. Paperback. 32 pgs.
