Heinrich Lamm

Heinrich Lamm (January 19, 1908 – July 12, 1974), a Jewish German-American physician, was a pioneer in using optical fibers for image transmission, and was the first to make a fiber-optic endoscope.

When Lamm was a medical student in 1930, he developed the first flexible fiber-optic bundle capable of transmitting images around curves. His initial purpose was to check inaccessible parts inside the human body. He reported his experiments, but the imaging quality was poor. Lamm's effort to file a patent failed due to a British patent already filed by Clarence Hansell. Provided by Wikipedia
