A teacher in Galicia, Spain, Ángela Ruiz Robles invented the first mechanical book way back in 1949. She was looking for a way to allow her students to carry fewer books to and from classes, so she created a mechanical encyclopedia. It was described as “a mechanical, electric, and air-pressure driven method for reading books.” Although patented, Robles’s creation did not get the funding it needed to succeed, putting her among many on a list of lesser-known female inventors.
