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.
Baedeker Blitz dropped 2,480 tons, more than the entire German effort. Furthermore, the report pointed out that these raids were confined to towns on or near the coast, and that fires caused by bombing only accounted for one-thirtieth of all the incidents dealt with by the Fire Service. The Baedeker-type raids ended in 1944, as the Germans realized they were ineffective; unsustainable losses were being suffered for no material gain. January 1944 saw a switch to London as the principal target for retaliation; on 21 January the "Luftwaffe" mounted Operation Steinbock, an all-out attack on London employing all of its available bomber
