"John Jacob Jingleheimer Schmidt" is a traditional children's song of obscure origin. The same verse is sung more and more softly in repetition. Its lyrics depend on who is singing. For example, sometimes they are this version:
John Jacob Jingleheimer Schmidt, That's my name too. Whenever we go out, The people always shout, "John Jacob Jingleheimer Schmidt!" Da da da da da da da da (or other folderol)
John Jacob Jingleheimer Schmidt, His name is my name too. Whenever I go out, The people always shout, "There goes John Jacob Jingleheimer Schmidt!" Da da da da da da da da
The mock German name celebrated in the song suggests that English-speaking children find long northern-European names to be inherently funny words. The surname "Schmidt" and the surname suffix "-heimer" are of Germanic origin. Schmidt is one of the most common surnames in German heritage.
While the origins of the song are obscure, some evidence places its roots with vaudeville and theatre acts of the late 19th century and early 20th century popular in immigrant communities. Some vaudeville acts during the era, such as the work of Joe Weber and Lew Fields, often gave voice to shared frustrations of German-American immigrants and heavily leaned on malapropisms and difficulties with the English language as a vehicle for its humor. Further, "John Jacob Jingleheimer Schmidt" shares many characteristics with "My Name is Jan Jansen", a song that can trace its origin to Swedish vaudeville in the late 19th century.
