Margaret "Mattie" Knight
Machinery Safety
-
Margaret "Mattie" Knight invented a device
to shut down machinery in a mill when something malfunctions to
avoid injury when she was just 12 years old.
-
She witnessed a
worker injured at the factory where her brother worked and
invented this device to prevent further injury.
- She did not receive her first patent until she was 30 when she invented
a machine to make flat bottoms for paper bags. This was Mattie's
first invention of many to follow.
- Mattie was a great girl inventor who became a
great woman inventor. You could do it too!
