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.
