* Johannes Gutenberg (c. 1400 - 1468) is widely credited with being the first to develop a practical and commercially successful system of printing with movable type in Europe. However, while he made significant advancements, he was not the first to use movable type.
* The Chinese were using movable type centuries before Gutenberg. Bi Sheng (990-1051) is credited with inventing clay movable type in China.
* The Koreans also developed their own system of metal movable type in the 13th century, before Gutenberg.
So, while Gutenberg is celebrated as the inventor of movable type in Europe, it's important to acknowledge the earlier advancements made in China and Korea.
