Around 1440, Johannes Gutenberg, a German goldsmith, invented the movable-type printing press. This innovation is considered one of the most influential events in human history. Before the press, books were painstakingly copied by hand by monks, making them incredibly expensive and accessible only to the clergy and the elite. Gutenberg’s press used metal alloys for the letters and an oil-based ink, allowing for the mass production of texts for the first time. The first major work produced was the 'Gutenberg Bible' in 1455. The printing press facilitated the rapid spread of ideas, leading to the Renaissance, the Reformation, and the Scientific Revolution. It democratized knowledge, increased literacy rates, and laid the foundation for the modern knowledge-based economy. Within decades, printing shops sprang up across Europe, transforming literature from a luxury for the few into a tool for the many, forever changing the way information is shared and preserved.
