When Narinder S. Kapany was in high school in the 1940s in Dehradun, an Indian city in the Himalayan foothills, his science teacher told him that light travels only in straight lines. By the time he entered graduate school at Imperial College London in 1952, he realized he wasn’t alone. For decades researchers across Europe had been studying ways to transmit light through flexible glass fibers. Professor Hopkins, a formidable theoretician, provided the ideas; Dr. Kapany, more technically minded, figured out the practical side. In 1954 the pair announced a breakthrough in the journal Nature, demonstrating how to bundle thousands of impossibly thin glass fibers together and then connect them end to end.
