Paul Nipkow

Paul Nipkow invented the Nipkow disk, a mechanical rotating device with a spiral of holes. This invention became the foundational technology used in the development of early mechanical television systems.

The spinning disk allowed light to pass through its holes in a scanning pattern, breaking an image down into individual lines. A receiver with a synchronized spinning disk could then reassemble these lines back into a moving image.

No, Nipkow's technology was strictly mechanical, whereas modern television relies on electronic scanning. However, Nipkow is still considered a vital television pioneer because his disk was the only way to broadcast images before electronic tubes were perfected.

Yes, Nipkow was still alive when Nazi Germany utilized early mechanical-electronic televisions to broadcast the 1936 Berlin Olympics. He was honored as the father of television by the regime during these early public broadcasts, though he reportedly disliked the medium.
