and from The Writer's Almanac:
It was on this day in 1456 that the first edition of the Gutenberg Bible was bound and completed in Mainz, Germany. The Gutenberg Bible was the first complete book printed with movable type. The press produced 180 copies of the Bible. Books had been printed on presses before, in China and Korea, with wood and bronze type; but Gutenberg used metal type, and made a press that could print many versions of the same text quickly. His contributions to printing were huge: he created an oil-based printing ink, he figured out how to cast individual pieces of type in metal so that they could be reused, and he designed a functioning printing press. But others before him had come up with similar ideas. Probably the most important thing that Gutenberg did was to develop the entire process of printing — he streamlined a system for assembling the type into a full book and then folding the pages into folios, which were then bound into an entire volume — and to do it all quickly. The techniques that Gutenberg refined were used for hundreds of years, and
the publication of the Gutenberg Bible marked a turning point in the availability of knowledge to regular people.
and from the Composers Datebook:
On this day in 1968, Czech conductor and composer Rafael Kubelik launches an appeal to world musicians to boycott performances in the five nations which invaded Czechoslovakia on August 20-21 until their military forces evacuate the country. The appeal was joined by Igor Stravinsky, Arthur Rubinstein, Yehudi Menuhin, Otto Klemperer, Bernard Haitink, Claudio Arrau, and others.
