When I get a little money I buy books; and if any is left I buy food and clothes.And remember, when he said this books were as new and revolutionary as the Internet is to us today.
--Desiderius Erasmus, 1466-1536
So today especially, let us salute Johannes Gutenberg who made all these books possible by inventing movable type and the printing press. (Wikipedia's entry on Gutenberg gives a brief, fascinating look at his life and his influence on the Renaissance, in the context of that amazing time.)
On the other hand, his inventions probably cost the jobs of many scribes who had been painstakingly copying every book by hand until then. I wonder if their guild transitioned them into making movable type and running the new printing presses.
Gutenberg. The first union buster?
