Michael S. Hart, American author, founded Project Gutenberg (born 1947)

Michael Stern Hart was an American author, best known as the inventor of the e-book and the founder of Project Gutenberg (PG), the first project to make e-books freely available via the Internet. He published e-books via ARPANET years before the Internet existed, and later on BBS networks and Gopher servers.

Project Gutenberg (PG) is a volunteer effort to digitize and archive cultural works, as well as to "encourage the creation and distribution of eBooks." It was founded in 1971 by American writer Michael S. Hart and is the oldest digital library. Most of the items in its collection are the full texts of books or individual stories in the public domain. All files can be accessed for free under an open format layout, available on almost any computer. As of 13 February 2024, Project Gutenberg had reached over 75,999 items in its collection of free eBooks.
