Udo Knorr
Udo Knorr (born April 20, 1887 in Würzburg , † July 10, 1960 in Munich ) was a German mechanical engineer .
He studied at the TH Munich with Leo Kadrnozka and Walther von Dyck , who had been working with integraphs since the beginning of the 1890s . On January 13, 1922 Knorr received his doctorate with the thesis About an integraph for the mechanical integration of a very general group of differential equations . He had taken up the construction principle of the screw with variable pitch from Bruno Abdank-Abakanowicz .
After the First World War he was employed by the Supreme Building Authority in Munich. Around 1920 he had patented his driving diagram (an integrated system to determine the speed and travel time of a train along the route depending on the route profile ) and had it built by the precision mechanics workshops Starkl . The Fahrdiagraph was relatively widespread, because at that time the travel times of trains were very often determined graphically in terms of driving dynamics .
