Hans Geiger - Major Accomplishments Geiger was awarded a Ph.D. by the University of Erlangen in 1906 and shortly thereafter joined the staff of the University of Manchester, where he became one of the most valuable collaborators of Ernest Rutherford. Rutherford's protege Hans Gieger would eventually become famous for the invention of a radioactive detector, the Gieger counter. Since alpha particles can penetrate thin walls of solids, Rutherford and Geiger presumed that they could also move through atoms. As a result of his efforts, he was able to discover bursts of radiation called cosmic-ray showers, and he concentrated on their study for the rest of his career. ."

Nuclear physicist Hans Geiger, whose surname is known all over the world for his invention of the radioactivity measuring device known as the Geiger counter, was born Johannes Wilhelm Geiger in Neustadt-an-der-Haardt, Germany on September 30, 1882.He was one of five children born to Wilhelm Ludwig Geiger, a philosophy professor at the University of Erlangen. Thus, the work of Rutherford, Geiger (who later became famous for his invention of a radiation detector)and Marsden helped to form the foundations of both quantum mechanics and particle physics. Hans Geiger - Simple English Wikipedia, the free encyclopedia Hans Geiger co-invented the Geiger Counter with Walther Muller in 1911. Even the label "atom" gives this impression, given that it's derived from the Greek word "atomos," meaning "indivisible.". He also helped Rutherford create the theory of the atom. That was done without my real involvement, he later told an interviewer [PDF]. Wilson noted Geiger's recollection that "One day Rutherford, obviously in the best of spirits, came into my [laboratory] and told me that he now knew what the atom looked like and how to explain the large deflections of the alpha-particles.
