When Lamm was a medical student in 1930, he first carried out the transfer of images by assembling a bundle of optical fibers. Lamm first invented enough flexible fiber optics to reach this remarkable goal - transmitting optic images around curves.
His initial purpose was to check those inaccessible parts inside human body. He reported his experiments, but the imaging quality was poor. Lamm's effort to file a patent was failed due to a British patent already filed by Clarence Hansell.
