The Hainzel crater was named after the Augsburg patrician Paul Hainzel. Hainzel had in the second half of the 16th century astronomer Tycho Brahe to support the construction of the first large-scale precision instrument of modern astronomy history, one made ​​of wood quadrant. He allowed Brahe, in the garden of their estate Augsburg the quadrant a radius of 19 feet ( about 5.5 meters) had to build. With this instrument, the zenith distance and position of heavenly bodies could be accurately measured. The accuracy of the machined brass quadrant was 10 seconds of arc. Brahe, however, has never conducted himself with the quadrant measurements. As of the date he left Augsburg for some time.
