Unser Lehrer Doktor Specht is a series of family author Kurt Bartsch, directors Werner Masten, Vera Loebner and Karin Hercher, shooting starting in 1991 in Germany. The episodes had a length of 52 or 46 minutes. For subsequent repetitions of the episodes of the first season, the episodes were cut to about 45 minutes.
