#AnonymousGenius: Mary Elizabeth Walton

The Nightingale-Bamford School celebrates 7 Days of Genius by sharing work from their Anonymous Project. As part of the Open Doors Leadership Program, every girl from Kindergarten through Class XII has researched, studied, and created a project celebrating the life and work of a female leader whose achievements have been elided by history.  In the lead up to 92Y’s Genius Festival, we’ll highlight some of these overlooked and anonymous female geniuses.

Check out Mary Elizabeth Walton. In 1879, she invented a method that helped cut down the amount of pollution emitted through the chimneys of locomotives, automobiles, and residences.  Later, she invented a method for reducing noise produced from the elevated railway.
