Who invented the printing press?

• A. Johannes Gutenberg
• B. Leonardo da Vinci
• C. Galileo Galilei
• D. Isaac Newton

Answer: (A)

Johannes Gutenberg is the one who revolutionized how information could be produced and shared. He developed the first practical system of movable metal type and combined it with a screw press and oil-based inks in the mid-1400s at Mainz, Germany. This allowed books to be copied quickly and in greater numbers than before, making them cheaper and more accessible. The result was a dramatic spread of knowledge that helped drive the Renaissance and the Reformation.

The other figures are known for different achievements: Leonardo da Vinci was a versatile inventor and artist, Galileo Galilei advanced astronomy and science, and Isaac Newton laid the foundations of classical physics and mathematics. None of them invented the printing press.
