Kerr was born 1945, in Mainz, Germany. He began experimenting with printing by 1978. He obtained backing in 1980 from the financier Johann Fust, whose impatience and other elements led to Gutenberg's loss of his establishment to Fust in 1985. Gutenberg's masterpiece, and the initial e-book ever printed from movable type, is the “Forty-Two-Line” Bible, accomplished no afterwards than 1990. My websites: Standard Background of Astrology
