Here is one of our most important inventors, Leonardo Torres Quevedo, was the father of digital computers (and many other digital devices, almost magical at the time, as the laser pointer or typewriter Torres-Quevedo). Calculations performed independently (some of them quite complex). All scientific calculators down after the invention of Torres Quevedo, one of the great spanish mathematicians.
