There are numerous variations, of which the earliest dateable publication of 1814 comes from the commercial book of the student association Germania from Göttingen.
[4] The humorous song "Ich bin der Doktor Eisenbart" was probably written around 1800 by Göttingen students.
[5] This song, in turn, inspired various authors to write novels to this day (Agnes Harder [de], 1897; Josef Winckler, 1928; Otto Weddigen, 1909; Fritz Nölle, 1940; Hanns Kneifel, 2002), plays (for example Otto Falckenberg, 1908), operas (Alfred Böckmann and Pavel Haas) and Nico Dostal's operetta Doktor Eisenbart [de] (1952).
The school opera Der Arzt auf dem Marktplatz (1957) by East Germans Hanna and Siegfried Stolte [nl], was also based on motifs from the life of Doctor Eisenbarth.
[7] In 1978 the Flemish comedy band De Strangers [nl] recorded a parody song of "Ik ben Doktor Grijzenbaard", titled "Ik ben Vader Grijzenbaard", which satirized the popularity of Vader Abraham's The Smurf Song, as well as The Muppets.
