Baedeker having 10,000 copies printed by the "Bibliographisches Institut." However, after some 1000 copies had been sold, the Russians said the guidebook contained military secrets in the form of a map showing the site of their "Kommandantura", and confiscated the remaining copies. New English titles during this time were 1927's "Tyrol and the Dolomites", 1931's "The Riviera" (including South Eastern France and Corsica), an edition of "Germany" for the 1936 Olympic Games, and 1939's "Madeira, Canary Islands, Azores, Western Morocco". 1948−1979: Karl Friedrich Baedeker (1910−1979) was the son of Karl Baedeker III, who was killed in action at the Battle of
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
