Narinder Singh Kapany coined the term 'fiber optics' in 1960, a word now fundamental to modern digital communication, yet he remains largely unknown outside scientific circles.

The Story

1
🎇 In 1953, in a cramped lab at Imperial College London, Narinder Singh Kapany and Harold Hopkins shattered the belief that light travels only in straight lines by transmitting clear images through bundles of glass fibers, laying the groundwork for the digital age.
2
Born in 1926 in Moga, Punjab, Kapany’s family traced their ancestry to Guru Amar Das, the third Sikh Guru, embedding a legacy of resilience and intellect that fueled his journey from rural India to global scientific acclaim.
3🛠️ After earning his Ph.D. in 1955, Kapany didn’t just stay in academia; he founded Optics Technology Inc. in 1960, pushing fiber optics from theory into commercial reality and pioneering the Silicon Valley startup model long before it became famous.
4Despite offers to serve India’s Defense Ministry as a scientific adviser in the 1950s, Kapany chose the uncertain path of innovation abroad, eventually holding over 120 patents spanning lasers, medical instruments, and pollution sensors.
