Inspiring Inventors and Their World-Changing Innovations

Johannes Gutenberg (ca. 1400–1468) revolutionized the world with the invention of the printing press using movable metal type. This innovation enabled books and writings to be reproduced much faster and cheaper. As a result, knowledge became accessible to a wide public, driving education and scientific progress decisively forward.
What was invented?
- Printing press with movable type
World-changing impact:
- Beginning of the era of mass communication
- Promotion of Enlightenment, science, and education
Fun Fact: The first major book Gutenberg printed was the so-called Gutenberg Bible.
Quote: "It is a press, certainly, but a press that does not oppress the people, but lifts them."

Thomas Alva Edison (1847–1931) was one of the most prolific inventors in history with over 1,000 patents. His best-known invention is the practical light bulb, but he also developed the {Phonograph}{A phonograph is an old device that could play music. Music wasn't stored digitally, but as waves etched into grooves on a round disk or cylinder. Similar to a record player.} and the first commercial electricity grid.
Famous inventions:
- Light bulb
- Phonograph (first sound recording device)
- Improved telegraph and electricity grid
World-changing impact:
- Electrification of cities
- Beginning of sound recording and playback
Fun Fact: Edison experimented with over 6,000 plant species to find a suitable filament for the light bulb.
Quote: "Genius is one percent inspiration and ninety-nine percent perspiration."

Nikola Tesla (1856–1943) was a Serbian-American inventor and visionary whose inventions still shape our world today. He is particularly known for the {Alternating current system}{Alternating current is electric energy where the current constantly changes direction – sometimes it flows forward, sometimes backward. This makes it easier to transport the current over long distances into homes and schools.}, which revolutionized the worldwide power supply.
Major inventions:
- Alternating current (AC) and the associated motor
- Tesla coil
- Wireless energy transmission
Impact on the world:
- Foundation of today's electricity grids
- Enabling electrical energy transmission over large distances
Fun Fact: Tesla claimed to have a memory like an elephant and could work out many of his inventions in his head without drawing them.
Quote: "The present is theirs; the future, for which I really worked, is mine."

Marie Curie (1867–1934) was a trailblazing scientist who was the first woman to win a Nobel Prize – and the only person to win it twice in different scientific fields (Physics and Chemistry). She researched radioactivity, discovered the elements polonium and radium, and developed new treatment methods against cancer.
Outstanding discoveries:
- Radioactivity
- Polonium and radium
Importance for the world:
- Foundations for modern cancer treatments
- New insights in physics and chemistry
- Encouraged women worldwide to study sciences
Fun Fact: During World War I, Curie developed mobile X-ray units ("Petites Curies") for medical care at the front.
Quote: "Nothing in life is to be feared, it is only to be understood."

Leonardo da Vinci (1452–1519) was not only a famous artist but also an outstanding inventor. He designed visionary machines, including early models for helicopters, tanks, and diving equipment. Many of his ideas were far ahead of their time and inspired subsequent generations of engineers and researchers.
Amazing inventions and designs:
- Flying machines
- Mechanical knight (robot)
- Inventions in anatomy and engineering
Influence on the world:
- Inspired generations with his sketches and discoveries
- Connection of art, science, and technology
Fun Fact: Leonardo's famous notebooks were written in mirror script, presumably to protect his ideas.
Quote: "Unique simplicity is the highest goal of art and science."
