London, 1954 — A narrow beam of light bounced through a twisted glass strand and emerged, still intact, at the other end. Watching it closely was a young Sikh scientist from Punjab, Narinder Singh Kapany, unaware that this single experiment would eventually power the global internet, high-speed medical imaging, and modern communication.
Today, we call it fibre optics — the backbone of our digital world. But few know that the man who first demonstrated it was not from Silicon Valley, but from Moga, Punjab.
Narinder Singh Kapany: The Boy from Punjab Who Followed the Light
Born in 1926 in Moga, British India, Narinder Singh Kapany showed an early fascination with physics and light. After earning his degree from Agra University and training at the Indian Ordnance Factories, he moved to London to pursue a PhD at Imperial College under the guidance of Harold Hopkins.
There, in 1954, Kapany conducted the historic experiment that led to the first successful transmission of an image through a bundle of optical fibers — a feat once believed to be impossible due to light scattering.
Inventing Fibre Optics Before It Was a Buzzword
Though fibre optics became a commercial phenomenon decades later, it was Kapany who first coined the term “fibre optics” in a 1960 Scientific American article. Over the next two decades, he published over 100 scientific papers, secured more than 120 patents, and developed technologies that would later revolutionize endoscopy, internet infrastructure, and high-speed data transmission.
While many engineers earned recognition for commercializing the technology, Kapany’s son, Raj Kapany, shared a more personal truth:
“Dad knew he was destined to start a company of his own. He got no greater pleasure than developing products and commercializing them.”
Indeed, Kapany wasn’t just a researcher; he was a doer — blending curiosity with entrepreneurship long before it became a startup cliché.
His story is also a reminder of how some of the most influential figures in tech history remain hidden in plain sight. Just like the mystery surrounding the true identity of Bitcoin’s creator, Satoshi Nakamoto, continues to spark global intrigue — with some even linking Twitter founder Jack Dorsey to the theory — Kapany’s documented genius was overshadowed by those who commercialized his vision.
Life in America: Innovation, Identity, and Impact
After moving to the U.S., Kapany worked at institutions like Bell Labs and later founded Optics Technology Inc. in 1960. He also served as a professor at Stanford and UC Santa Cruz, mentoring generations of physicists.
Outside the lab, he built one of the world’s largest private collections of Sikh art and founded the Sikh Foundation in 1967, aiming to preserve and promote Sikh heritage worldwide.
In a heartfelt tribute, former Prime Minister Dr. Manmohan Singh wrote:
“I think our best tribute to Dr. Kapany would be to finish some of the projects that he had envisaged and promote Sikh studies among the diaspora.”
Those words echoed not just scientific legacy, but cultural responsibility — a call to action for future generations.
Recognition Came Late — But It Came
In 2021, the Indian government posthumously awarded Narinder Singh Kapany the Padma Vibhushan, India’s second-highest civilian honor — almost 70 years after his ground-breaking discovery.
Kapany passed away on December 4, 2020, in California at the age of 94. His death was mourned across scientific, academic, and Sikh communities worldwide, with tributes pouring in for a man who quietly revolutionized communication technology.
His legacy now lives in every video call, every fiber-powered surgery, every data center, and every beam of light that carries your voice across continents.
