The Inventions and Discoveries in 1947

1947 was indeed a year of great significance for history, as it marks the beginning of a new era of technological advancements and numerous innovations. The year was marked by numerous notable inventions that revolutionized various industries and fields. In this article, we take a closer look at some of the most crucial inventions and discoveries that took place in 1947.


The invention of the transistor has been described as the greatest invention of the 20th century, and it is undoubtedly one of the most significant inventions to have emerged from 1947. The transistor was invented by John Bardeen, William Shockley, and Walter Brattain at Bell Laboratories on December 23, 1947. The invention of the transistor marked the emergence of the modern electronics industry and paved the way for the development of numerous electronic devices used today, including computers, radios, and televisions.

Before the transistor came into existence, vacuum tubes were used to amplify and control electrical signals. However, vacuum tubes were large, fragile, and consumed a lot of energy, making them impractical for use in portable devices. The transistor was smaller, faster, and consumed less power, making it perfect for use in electronics products, especially portable ones. As such, this invention was a crucial invention that influenced the growth of the technology industry.

Polaroid Camera

The Polaroid camera was invented in 1947 by Edwin Land. The camera allowed users to take instant photos without the need for film processing. It was one of the first examples of instant gratification technology in photography. When you took a photo, it would be printed out immediately on the spot, using Polaroid film.

The Polaroid camera was a significant invention for various reasons, not just because of its ability to produce prints instantly. It gave birth to a new form of photography called instant photography, which was a game-changer at that time. It allowed users to take photos on the spot, a luxury that was not previously available unless you had access to a darkroom. This invention made photography more accessible to everyone, and it paved the way for modern instant photography. Today, instant cameras are smaller, lighter, and better quality, but without Edwin Land's invention, they would not exist.

Sound Barrier Broken

On October 14, 1947, Chuck Yeager became the first person to break the sound barrier. At the time, this was a significant milestone in the history of aviation and technology. Yeager attained the supersonic speed of Mach 1.07, which is equivalent to about 700 miles per hour. The accomplishment was significant because scientists were not sure if it was even possible to fly that fast without facing grave consequences. Yeager's achievement represented a significant breakthrough that revolutionized aviation technology, making supersonic travel a possibility.

Yeager's journey exemplified the importance of scientific experimentation and the willingness to push boundaries and take risks. His achievement influenced the development of faster aircraft, and it was instrumental in shaping the world of aviation as we know it today.


1947 was indeed a remarkable year for technology and innovation. The inventions and discoveries that emerged in that year laid the foundation for many modern technologies we use today. The invention of the transistor revolutionized the electronics industry, while instant photography was made possible by the invention of the Polaroid camera. Yeager's accomplishment in breaking the sound barrier paved the way for supersonic travel. These inventions and milestones prove that human ingenuity knows no bounds, and that we should always strive to think outside the box, push boundaries and make history with our inventions.


In 1947, a small electronic device called the transistor was invented by scientists John Bardeen, Walter Brattain, and William Shockley. This small but powerful device was able to amplify electrical signals, and it replaced the bulky and unreliable vacuum tubes that had been used previously. With this invention, the groundwork was laid for modern electronics as we know it today.

Invention and Development

The invention of the transistor was a major breakthrough for the electronics industry. Prior to its invention, vacuum tubes were commonly used to amplify electronic signals, but they were bulky, fragile, and consumed a lot of power. They also produced a lot of heat, which made them unreliable for use in more complex electronic devices.

In 1945, Bardeen, Brattain, and Shockley began experimenting with materials such as germanium, a metal-like element that was semiconducting in nature. They developed a small device that was able to amplify electrical signals without the need for vacuum tubes, and it was called the transistor.

The first patent for the transistor was filed in June 1948, and it was not until the early 1950s that it was put into commercial use. The transistor was seen as a breakthrough invention, and it quickly replaced vacuum tubes in electronic devices such as radios, televisions and computers.


The invention of the transistor revolutionized the electronics industry and paved the way for the development of modern electronics. It was smaller, more reliable, and more affordable than vacuum tubes and enabled electronics to become smaller and more portable. The transistor also enabled new technologies such as satellite communication and space exploration.

The invention of the transistor also laid the groundwork for the development of microelectronics. It enabled the miniaturization of electronic circuits, and has led to the development of modern computer chips, smartphones, and other electronic devices.

Overall, the invention of the transistor has had a profound impact on society and has transformed the way we live, work, and communicate.


The invention of the transistor earned Bardeen, Brattain, and Shockley the Nobel Prize in Physics in 1956. This invention made them pioneers in the field of semiconductor electronics and inspired countless other scientists and engineers to push the boundaries of technology and innovation.

The transistor also paved the way for the development of other semiconductor technologies such as integrated circuits and microprocessors. These technologies have revolutionized the world of computing and electronics, and they continue to shape our lives today.

Overall, the transistor is one of the most important inventions in the history of electronics and has had a profound impact on our lives. It serves as a reminder of what can be accomplished through scientific research and innovation.



In 1947, Walter Frederick Morrison invented a plastic flying disc that he named the "Pluto Platter." It was designed to be thrown and caught, mimicking the motion of a UFO. Morrison's prototype was made of a cake pan and drew inspiration from the Frisbie Pie Company, whose empty pie tins were often used as toys. His flying disc was later renamed by the Wham-O toy company to the Frisbee. The Frisbee's initial popularity came from college students who discovered it to be a fun and easy recreational activity. The use of the disc caught on and within a few years, people of all ages were throwing it around in parks and on beaches. Wham-O's ownership of the patent made it the most commercially successful flying disc in history.
