Bothe, << BOH tuh, >> Walther (1891-1957), a German physicist, shared with Max Born the 1954 Nobel Prize in physics for the “coincidence method and his discoveries made with it.” This method couples the electric circuits of two Geiger counters so that they register only when both are triggered by passing radiation. Among its uses in nuclear research is the determination of the direction from which cosmic rays come. Bothe was born on Jan. 8, 1891, in Oranienburg, Germany. He taught at the universities of Berlin, Giessen, and Heidelberg. Bothe died on Feb. 8, 1957.
