Baedeker work involved in preparing the city guides titled Baden-Baden, Constance, Strasbourg and Wiesbaden, published in the mid-1970s. He also produced several short city guides. Basel, the Swiss city which was first covered in a Baedeker guidebook by Karl Baedeker himself in his most celebrated guidebook "Schweiz", first published in 1844, was the title of Florian's own guide, published in 1978. It is considered by many to be one of his best city guides. Florian Baedeker. a keen parachute jumper, was killed in a parachuting accident on October 26, 1980. He was 36. Following the death of Florian, his mother, Karl
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
