Happy Birthday Johannes Gutenberg! 🎉 To celebrate, watch how Gutenberg’s printing press works. Gutenberg introduced several new elements that helped mechanize the process of printing using metal movable type. He devised a method to cast uniform metal type, innovated a durable oil-based ink, and modified a screw-operated wooden press (think a wine or olive press) that made printing faster and more efficient. The result was revolutionary. #OnThisDay #BibleImpact #Gutenberg | Museum of the Bible
