Baedeker Baedeker entered a new era. In 1974, the first post-war international guidebook appeared, financed largely by the German airline "Lufthansa"—the voluminous 872-page "Baedekers USA" in German, which had the look of traditional pre-war Baedekers. Florian Baedeker (1943−1980), the only son of Karl Friedrich Baedeker, succeeded him when he died in 1979. After completing his studies in Munich in 1971, he had devoted himself to matters relating to book publishing under the guidance of his father, and had helped him with the preparation of the "Munich" guide, released for the 1972 Munich Olympic Games. Florian also carried out most of the
Karl Baedeker (scientist) This was the first example of doping a semiconductor to change its properties and also the discovery of transparent conductive materials. He also observed a Hall effect in transparent copper iodide thin films that had the reverse sign to that in copper, an observation of what was later to be known as conduction by electron holes in semiconductors. This observation was critical in developing the theory of electron conduction in solids. Along with his graduate student Karl Steinberg, Baedeker studied the effect of varying concentration of iodine on the electrical properties of copper iodide. He also is credited with making
