Gutenberg's Bible

The Writer's Almanac informs me that on this day in the year 1452 Johannes Gutenberg finished printing the first section of his revolutionary bible.  More than a decade earlier, he had begun isolating the elements of each letter and punctuation mark (300 shapes in all) to create movable type. 

It's a technology that had begun in China centuries earlier, using porcelain. Gutenberg's type pieces were made of an alloy of lead, tin and antimony — a compound that remained in use for the next 550 years. 

Gutenberg printed around 180 bibles of which less than 50 remain, only 21 of them complete. But his printing press forever changed our technology and our culture. 

"What the world is today, good and bad, it owes to Gutenberg," Mark Twain wrote in 1900. Perhaps a little less true today, but still a statement you can hang your hat on.
