Baedeker in English. "The Rhine" appeared in 1861. The Scottish brothers James Francis Muirhead (1853−1934) and Findlay Muirhead (1860−1935) played a significant role in popularising the English guidebooks worldwide. James, the elder brother, had been taken on as editor of the English editions by Fritz Baedeker in 1879, at age 25; Findlay joined him later as joint editor. They were responsible for all the Baedeker editions in English for almost forty years. James Findlay is given the credit for two-thirds of the content in the "Canada" guidebook, first published in 1894. The "Canada" guide is the sole classic Baedeker to have
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
