Harold Knerr - Dinglehoofer Und His Dog Adolph

On May 16, 1926, Knerr started Dinglehoofer und His Dog Adolph, a topper which accompanied The Katzenjammer Kids until two years after his death. By 1936, to avoid any association with Adolf Hitler, the dog's name was changed to Schnappsy.

Knerr never married. In New York during the 1940s, he lived in the Hotel Blackstone at 50 East 58th Street. On July 8, 1949, he died in Manhattan from heart disease, survived by a sister in Carmel, California and a brother in Philadelphia.
