I started working years ago at a daily newspaper that still used linotype machines. It was thrilling to watch the muscled print-setters pour heavy vats of molten lead into the printing plates, page by page.
I think it was A&E's Biography a few years ago that gave the nod to Gutenberg as the most influential person (besides Christ) in history.
All things work for the glory of God.
Just recently a wide group of historians were polled for the top technological advancement with the most impact on the world, and Gutenburg's printing press was the landslide winner.
