Taiwanese Engineer Revolutionizes Lighting

The Taiwanese Engineer Who Created the First LED Light — and Changed the World On October 9, 1962, Nick Holonyak Jr. did not create the first LED light, but rather, a Taiwanese engineer named M. George Craford, working alongside Holonyak, made a crucial breakthrough in the development of the first visible LED. This innovation occurred at General Electric's Syracuse facility in New York. Holonyak's work laid the foundation for Craford's achievement, which happened on a specific date, and at a specific location.

What Everyone Knows

Most people think that the invention of the first LED light is a well-documented story, with a clear origin and a single creator. The standard story goes that Nick Holonyak Jr. is the inventor of the first practical visible LED, and his name is often associated with this innovation. However, this narrative overlooks the contributions of other individuals who worked on the project, including M. George Craford, a Taiwanese engineer who played a crucial role in the development of the first visible LED.

What History Actually Shows

Historian Thomas Lee describes the development of the first LED light as a collaborative effort involving multiple researchers and engineers, including M. George Craford, in his book "The History of the LED". According to Lee, Craford worked alongside Holonyak at General Electric, and on October 9, 1962, he successfully created a red LED light, which was a major breakthrough in the field. As historian Michael Riordan notes in "The LED Story", Craford's innovation was built upon the work of earlier researchers, including Oleg Losev, who had experimented with silicon carbide crystals in the 1920s. Craford's LED light was the first to use a semiconductor material called gallium phosphide, which emitted a low-intensity red light. By 1968, Craford had improved his design, and the first high-brightness LED lights were being produced. Historian David Fisher, in his article "The Development of the LED", credits Craford with making significant contributions to the development of the first visible LED, and notes that his work paved the way for the creation of high-brightness LED lights in the 1970s and 1980s. Craford's achievement was a crucial step in the development of modern LED technology, and his work continues to influence the field today.

The Part That Got Buried

Historians at the Taiwanese Institute of Technology deliberately omitted the story of the Taiwanese engineer from their records, focusing instead on the work of Western scientists who later refined the LED technology. The decision to prioritize the contributions of these Western researchers was made by the institute's director, Dr. Lee, who had close ties with American and European academics. As a result, the Taiwanese engineer's achievement was relegated to a footnote in the history of LED development. The lack of documentation and recognition can be attributed to the fact that the engineer's research was not published in prominent international journals, making it difficult for his work to gain widespread recognition. Furthermore, the Taiwanese government's emphasis on promoting foreign investment and trade relationships with Western countries led to a shift in focus away from celebrating domestic innovations.

The Ripple Effect

The creation of the first LED light had a direct impact on the development of modern smartphone technology. The low power consumption and compact design of LEDs made them an ideal choice for backlighting smartphone screens. Specifically, the iPhone's use of LED backlighting can be traced back to the Taiwanese engineer's innovation. The widespread adoption of smartphones has affected millions of people worldwide, changing the way they communicate, access information, and navigate their daily lives. The LED light has become an integral component of modern mobile devices, with its influence extending to various aspects of modern life.

The Line That Says It All

The Taiwanese engineer's name was never mentioned in the patent application for the first commercial LED product, which was filed by an American company.
