The first "planisphere" star chart was made in 1625 by the son-in-law of Johannes Kepler, Jacob Bartsch. Planispheres are generally composed of two adjustable disks that rotate on a common point and can be moved to display the visible stars for any given time and date. Its predecessor is the astrolabe. Friedrich Anton Frank was a Slovenian mathematician and professor, and authored several books on astronomy.
