Today, the wide variety of modern endoscopes allows routine diagnostic examinations. Precise observation is possible because of excellent optical and light transmission. Surgery can be performed while viewing a television screen, and video documentation and intraoperative photography are possible with outstanding quality. The invention of a rod-lens optical system by Harold H. Hopkins, PhD, in 1959 and the addition of fiberoptic light transmission by Karl Storz in 1960 marked a breakthrough in modern endoscopy. This article summarizes an interview with the instrument maker, Karl Storz.
