Before the Battery: Dreaming of the Digital Page
The idea is older than the internet. In 1949, Spanish teacher Ángela Ruiz Robles patented a "mechanical encyclopedia" — spools of text, a magnifying lens, and a tiny light so students could carry their lessons in one slim case. It never went to market, but it imagined the e-reader decades early.
Then in 1971, university student Michael S. Hart typed the U.S. Declaration of Independence into a mainframe and launched Project Gutenberg — the first effort to make books free, digital, and forever. Content arrived long before the hardware to read it comfortably.
