Michael Stern Hart (March 8, 1947 – September 6, 2011)[1] 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.[1][2][3][4] He published e-books via ARPANET years before the Internet existed,[5][6] and later on BBS networks[7] and Gopher servers.[8]
Hart devoted his life after founding PG in 1971 to digitizing and distributing literature from works in the public domain with free and expired copyrights. The first e-books[5][9] were typed in plain text format[6][7] and published as text files; other formats were made available later. Hart typed most of the early e-books himself; later, volunteers expanded the project.[5][10][11]
