All tools or technology that exist today, of course, have their first inventor. For example 4 great inventions that have changed this world.
Printing Press
Initially, printing techniques began on the Asian continent, to be precise in China and Korea. Printing techniques were first discovered in China in the 11th century. Then, Korea further developed the printing technique.
Well, in Europe, the printing technique was popularized by Johannes Gutenberg, a German who was born in 1398. Gutenberg invented printing technology in the 1450s. He introduced the printing press using wooden blocks to press ink onto paper. The printing press he made could produce prints in large quantities, around 1,000 pages per day. Well, since then, the printing press began to spread in Europe, even in the world. Thanks to the invention of the printing press, newspaper and book publishing has grown rapidly all over the world.
Typewriter
You are certainly familiar with the term qwerty. Yes, the term is usually used on the keyboard. Well, Christopher Latham Sholes is the person behind the development of the typewriter. In fact, he is called the Father of The Typewriter.
When he was young, Christopher Latham Sholes worked as a reporter for a newspaper. Every day he wrote the news with pen and ink. Tired of that, he finally tried to design a machine that made it easier to write. Since then, he began to develop the machine he invented.
After many experiments, in 1867 the first typewriter appeared. In 1878, he succeeded in inventing the shift key to tap capital and lowercase letters. It was found after he found the arrangement of letters with the qwerty formation on a typewriter.

Airplane
On December 17, 1903, Orville and Wilbur Wright made their first successful flight in an airplane. This event marked the birth of the modern aviation era. Orville and Wilbur Wright were born and raised in Dayton, Ohio, United States. The brothers became very interested in aviation after learning about glide flight from a German engineer named Otto Lilienthal in the 1880s.
Orville and Wilbur did not go to college, but both had excellent technical abilities. After doing various research on airplanes, the Wright brothers made their first trials in 1900. Then, in 1901, they used a new design and the results were better than before.
Their glider is equipped with a rudder system that can be moved. Finally, in December 1903, the airplane managed to stay in the air for 12 seconds and flew 120 feet. Since then, Orville and Wilbur have continued to experiment. In 1909, the United States Army Corps purchased this special aircraft made by the Wright brothers and marketed it.
Steam Train
The steam train locomotive was first built in 1804 by Richard Trevithick. The train was propelled by a high-pressure steam engine. February 21, 1804, became the first steam train trip created by Richard Trevithick, which was made on the tram line owned by the iron factory.
However, when steam trains operate, people are afraid to ride them. They are afraid of the shaking. However, because the cost is cheap and the travel time is short, trains have finally become a much-loved means of transportation.
The discovery of the steam train cannot be separated from the services of James Watt, the inventor of the steam engine. The steam engine invented by James Watt could drive train wheels. Since then, rail transportation in the world has been growing.
