Ángela Ruiz Robles (Villamanín, March 28, 1895-Ferrol, October 27, 1975) was a Spanish teacher, writer and inventor.
She was the inventor of a mechanical encyclopedia that could well be considered the first electronic book in history, being twenty years ahead of the device designed in 1971 by the American Michael Hart and more than half a century ahead of current e-books.
In 1944 he carried out the scientific-grammatical atlas project, with the aim of making Spain known with grammar, syntax, morphology, spelling and phonetics. Later he carried out the project for the shorthand typing machine. In 1949 he developed the first mechanical encyclopedia proposal.
