Editing The Katzenjammer Kids (section)

== Characters and story ==
''The Katzenjammer Kids'' (three brothers in the first strip but soon reduced to two) featured Hans and Fritz, twins who rebelled against authority, particularly in the form of their mother, Mama; der Captain, a sailor who acted as a surrogate father; and der Inspector, a long-bearded school official. Other characters included John Silver, a pirate sea captain; the Herring Brothers, John Silver's three-man crew; and King Bongo, a primitive-living but sophisticated-acting [[Black people|Black]] jungle monarch who ruled a tropical island.

As originally created, Mama's husband was Papa Katzenjammer, her brother was the bungling sailor Heinie, and der Captain–introduced in 1902—was Heinie's boss. After a short while, Papa was dropped from the strip without explanation, with der Captain taking over his function. By the 1940s, der Captain and Mama were often presented as a de facto couple.

The immediate Katzenjammer family usually spoke stereotypical German-accented English. When first introduced, der Captain and der Inspector did not, but within months adopted the accent as well. During World Wars I and II, when the United States was at war with Germany, the Katzenjammer family were temporarily presented as Dutch.

The defining theme of the strip was Hans and Fritz pranking der Captain, der Inspector, Mama, or all three, for which the boys were often spanked, but sometimes shifted the blame to others. Other stories involved der Captain taking the Katzenjammers on treasure hunts or cargo voyages, sometimes aided by or competing with John Silver. Still other stories involved King Bongo enlisting the Katzenjammers to run errands or go on missions related to his kingdom; in both strips, by the mid-1930s, the family lived on Bongo's island—usually called Squee-Jee—and were readily at hand.

Knerr's version of ''The Katzenjammer Kids'' introduced several major new characters in the 1930s. Miss Twiddle, a pompous tutor, and her brainy niece Lena came to stay permanently with the Katzenjammers in early 1936. Later in the year, Twiddle's ex-pupil, "boy prodigy" Rollo Rhubarb joined them. The ever-smug Rollo is always trying to outwit Hans and Fritz, but his cunning plans often backfire.

''The Captain and the Kids'' also introduced some new characters. Ginga Dun is a snooty Indian trader who can outsmart almost anyone and only talks in verse. Captain Bloodshot is a pint-sized pirate rival of [[Long John Silver|John Silver]].

Notable features of the later strips, at both syndicates, included a more constructive relationship between the Captain and the boys, who sometimes bickered like friendly rivals rather than pranking each other outright. The King and his people, also in both strips, were now Polynesian rather than African.
