Father Gregor (Bernhard Helms; b. 1946) is a Benedictine monk of the abbey Sankt-Stephan in Augsburg, Germany. As a physics-astronomy teacher, he followed tradition by building his own observatory and school planetarium. The abbey's museum exhibits precious historical instruments of J. Fraunhofer and G. F. Brander.
