On July 11, 1871, she became one of the first women to receive a patent. Knight went on to patent at least 27 inventions (as well as many more that were never officially filed) and became something of a media sensation. She was one of the first women to be able to not only create a work of art or machinery but to also put her full name on it — though “M.E. Knight” appears on much of the official patent documentation, she also clearly wrote “Margaret” out in full. Knight was a rare role model for women who wanted careers in the male-dominated fields of mechanics and invention.
