Georg Will studied physics and crystallography a the Technische Hochschule M�nchen. In 1961 he moved to the USA, where he worked at the Brook National Laboratory, where in collaboration with Walter Hamilton the idea was born to analyse crystal structure from powder diffraction data using a POWLS program. A decisive step forward came in the 1980's when he worked with Bill Parrish at the IBM Research Laboratory in San Jos�, California. At that time the "two stage method" was developed to its present state, beginning the analysis of computer based profile fitting followed by least squares refinements and Fourier methods. He returned to Germany in 1965 and to Bonn in 1969, where he concentrated on neuron diffraction for the study of crystal and magnetic strucutres using the "two stage method".The "Rietveld method" was also applied, although it was only useful for limited and some well defined problems. Later he extended his interest to in-situ high pressure diffraction with synchroton radiation. In 1990 with the newly developed position-sensitive detector JULIOS, diffraction experiments were started at the spallation source ISIS in England. Through the simultaneous recording of angles and energies, this detector in combination with the "two stage method" gave a specific advantage in studying powders as well as single crystals (Laue diffraction) with spallation source neutrons.
