Angela Ruiz Robles

Angela Ruiz Robles (March 28, 1895 Villamanín, Leon - October 27, 1975, Ferrol, A Coruña) was a Spanish teacher, writer, pioneer and inventor of the mechanical precursor to the electronic book.

In 1949, Ruiz was awarded Spanish patent 190,698 for the "Mechanical Encyclopedia" (Spanish: la Enciclopedia Mecánica).

Ruiz Robles wanted to lighten the weight of the books carried by her students, so she devised a device consisting of a series of text and illustrations on reels, all under a sheet of magnifying glass with a light for reading in the dark, and was to incorporate spoken descriptions of each topic. Her device was never put into production but a prototype is kept in A Coruña National Science and Technology Museum.
