Top 10 Inventions Whose Credit Was Given to the Wrong People

While many are familiar with how Thomas Edison took credit for inventions that were actually just enhancements of others' creations, this list dives deeper—expanding to include figures and innovations you might not expect. Here, we highlight remarkable devices that greatly impacted modern history, but whose inventors often remain unrecognized.

10. Computer Desktop and Graphical User Interface

Claimed Inventor: Microsoft (with Windows) True Inventor: Xerox PARC

The idea of a graphical user interface (GUI) and desktop metaphor (controlled with a mouse) is most commonly associated with Microsoft’s Windows operating system. This has led many to mistakenly think Microsoft invented it. The story, however, is more intricate: Xerox created the system (Xerox Alto personal computer) inspired by Doug Engelbart’s earlier work and shared it with Apple. Apple was impressed and developed its own version, clearly influenced by Xerox's design, launching the first successful commercial version on January 24, 1984 – the Macintosh. Microsoft, on the other hand, didn’t release Windows until November 1985, and it lacked the ability for overlapping windows (except in dialog boxes) because Apple owned the patent. Microsoft’s system wasn’t an operating system either, but rather an interface that ran on top of MS DOS.

9. Automobile

Claimed Inventor: Henry Ford True Inventor: Karl Benz

While several other German engineers, including Gottlieb Daimler, Wilhelm Maybach, and Siegfried Marcus, were also working on the idea around the same time, Karl Benz is generally recognized as the creator of the modern automobile. His four-stroke cycle gasoline engine-powered automobile was built in Mannheim, Germany in 1885 and received a patent in January of the following year through his company, Benz & Cie., founded in 1883. This was a complete, innovative design incorporating several new technological features, making it worthy of a patent. Benz began selling production models in 1888, while Henry Ford didn’t build a self-propelled vehicle until 1896—over ten years after Benz.

8. X-Ray Photography

Claimed Inventor: Thomas Edison True Inventor: Wilhelm Röntgen

Although Edison's Fluoroscope became the standard tool in medicine, it wasn’t the first instance of x-ray photography. On December 22, 1895, Wilhelm Röntgen, a German physics professor, observed an image of his wife’s hand on a photographic plate created by X-rays. This image (shown above) was the first-ever photograph of a human body part using X-rays. Röntgen's groundbreaking work in X-rays and X-ray photography was so influential that X-rays are also known as Röntgen rays in his honor.

7. Moving Pictures

Claimed Inventor: Thomas Edison (though his own moving pictures concept was developed by one of his employees, William Dickson) True Inventor: Louis Le Prince

The clip above, which holds the distinction of being the first moving picture, was captured at a rate of 12 frames per second by French inventor Louis Le Prince. It was filmed at the home of Joseph and Sarah Whitley in Roundhay, Leeds, West Yorkshire, England, on October 14, 1888. The people appearing in the footage are Adolphe Le Prince (Louis’s son), Sarah Whitley, Joseph Whitley, and Harriet Hartley. Tragically, Sarah Whitley passed away just ten days after the filming. Two years later, Le Prince mysteriously disappeared from a train traveling between Dijon and Paris. Another two years after that, his eldest son, Alphonse, was found shot dead in New York after testifying against Edison in a patent trial involving the American Mutoscope Company. Edison’s first moving picture, *Monkeyshines*, would not be released until 1889 or 1890.

6. Telescope

Claimed Inventor: Galileo True Inventor: Hans Lippershey

The first functional telescopes, dating back to 1608, are credited to Hans Lippershey. Other figures such as Zacharias Janssen, a spectacle-maker in Middelburg, and Jacob Metius of Alkmaar, also claimed to have invented the device. These early telescopes were refracting designs, utilizing a convex objective lens and a concave eyepiece. Galileo adopted this design the following year. By 1611, Johannes Kepler proposed a new design, using both a convex objective and eyepiece lenses. By 1655, astronomers like Christiaan Huygens began crafting larger and more powerful Keplerian telescopes, although they were still cumbersome and difficult to handle.

5. Recorded Audio

Claimed Inventor: Thomas Edison True Inventor: Édouard-Léon Scott de Martinville

Thomas Alva Edison conceptualized the idea of recording and playing back sound between May and July of 1877, during his work to automate telegraph messages and transmit speech for the telephone. He introduced his invention, the phonograph, on November 21, 1877. However, 17 years earlier, in 1860, the French inventor Édouard-Léon Scott de Martinville had already created the phonautograph, which could record sound on a visible medium but lacked the capability to play it back. The recordings, known as phonautograms, were first successfully played back using computer technology in 2008, and the result is the voice of a woman singing “Au clair de la lune,” recorded 149 years ago when James Buchanan was the U.S. President and Napoleon III ruled France.

4. Lightbulb

Claimed Inventor: Thomas Edison True Inventor: Sir Humphry Davy

In 1802, Sir Humphry Davy, using what was then the most powerful electrical battery in existence at the Royal Institution of Great Britain, created the first incandescent light. He passed an electrical current through a thin platinum strip, a metal chosen for its very high melting point. While this light was too dim and short-lived to be practical, it laid the foundation for future advancements, paving the way for numerous inventors over the next 75 years, culminating in Thomas Edison’s development of the first commercially viable incandescent lamp in 1879.

3. The Internet

Claimed Inventor: Al Gore (although he never claimed to have 'invented' the internet, he did state: 'During my service in the United States Congress, I took the initiative in creating the Internet.') True Inventors: The real pioneers of the Internet, specifically the creators of ARPANET from which the Internet evolved, are Vinton Cerf, along with Lawrence Roberts, Leonard Kleinrock, and Robert Kahn.

Vinton Cerf (born June 23, 1943) is an American computer scientist widely regarded as one of the primary figures in the development of the Internet, often referred to as 'the father of the Internet.' His work has earned him numerous honors, including the National Medal of Technology, the Turing Award, and the Presidential Medal of Freedom. As a graduate student, Cerf studied under Professor Gerald Estrin and worked with Professor Leonard Kleinrock on a data packet networking project that connected the first two nodes of ARPANET, the precursor to the Internet. It was here that he helped develop a host-to-host communication protocol. While at UCLA, he also met Robert E. Kahn, who was working on ARPANET’s hardware architecture. Cerf has served as Google’s Vice President and Chief Internet Evangelist since 2005.

2. Powered Flight

Claimed Inventor: The Wright Brothers True Inventor: Richard Pearse

While the Wright Brothers are often credited with being the first to achieve a powered, sustained, heavier-than-air flight, it was actually Richard Pearse from New Zealand who accomplished the feat nine months earlier, on March 31, 1903, in Timaru, New Zealand. Pearse's machine, though lacking an aerofoil wing, was much closer in design to modern aircraft than the Wright brothers' plane. It featured a monoplane design instead of a biplane, a tractor propeller instead of a pusher, rear stabilizers and elevators rather than those at the front, and ailerons for banking control instead of the Wrights’ wing-warping technique. Pearse’s flying machine closely resembled today’s microlight aircraft.

1. Radio

Claimed Inventor: Guglielmo Marconi True Inventor: Nikola Tesla

In 1895, Marconi presented a device to the public in London, claiming it as his own invention. However, despite his assertions, the device closely resembled the designs described by Tesla in his widely published articles. Marconi’s later four-tuned system was actually preceded by the works of Nikola Tesla, Oliver Lodge, and J. S. Stone. Marconi’s transmission in late 1895 reached a distance of approximately one mile. Nikola Tesla, the electromechanical engineer often credited as the father of wireless telegraphy, was one of the first to patent a reliable method for generating radio frequency waves. Between 1895 and 1899, Tesla reported receiving wireless signals over long distances, though independent evidence to support these claims is lacking. As Tesla explained, 'The popular impression is that my wireless work was begun in 1893, but as a matter of fact I spent the two preceding years in investigations, employing forms of apparatus, some of which were almost like those of today...'
