Karl Baedeker (scientist) Karl Baedeker (scientist) Karl Wilhelm Sali Baedeker (3 February 1877 – 6 August 1914) was a German physicist, and a professor at the University of Jena. He was the grandson of Karl Baedeker, the founder of the eponymous travel guide publishing house, and the son of Fritz Baedeker (1844 - 1925), who ran the same company from 1869 until his death in 1925 (see Baedeker). One of his scientific discoveries was that the resistivity of cuprous iodide (CuI) depended on its stoichiometry. Thin films of the material became much more conductive when exposed to iodine vapor; the effect was reversible.
Karl Baedeker Herbert Warren Wind, had spent a considerable amount of time at the contemporary Baedeker publishers in Germany, researching the history of the firm. He gave the following account, related by Gisbert von Vincke, a German Shakespearen scholar, of the famous "Milan Cathedral" story, which has acquired a legendary status of its own, because of its manifold variations: On descending from the roof, Baedeker reversed the pea-transferring process, thus ensuring that there was no error in his calculations. The number of peas multiplied by 20 plus any steps remaining had given him the correct count. A few years after Karl Baedeker
