With the start of the Nederlandse Instrumenten Compagnie (Nedinsco) in Venlo, Carl Zeiss Jena was able to design and produce high-quality optical equipment in the 1920s and 1930s. For example rangefinders, periscopes, signal lamps, measurement and fire-control systems and medical equipment. Nedinsco moved into Venlo’s first skyscraper, popularly – and still today – known as the Nedinsco Tower. After World War II, the 34-meter tower was taken over by the former Nederlandse Beheersinstituut (Dutch State Management Institute). The surrounding factory buildings had been extensively damaged by the heavy bombing of the Maasbrug bridge in Venlo.
