George Herriman is of course most well known for his masterpiece of a comic strip, Krazy Kat, but prior to the Kat's kreation creation Herriman penned several other strips which lasted for varying amounts of time. Professor Otto and His Auto lasted less than a year, beginning in March 1902 and most likely not lasting into 1903. Today's comic is probably the last Professor Otto strip that ran.
The strip was, as the title suggests, about a professor and the various things he does while in his automobile. I guess one thing he really enjoys is running into things with it, so his resolution is to only run into snowmen from now on. It seems causing emotional trauma to children is preferable to causing physical harm to people, at least in his mind. Mistaking Henry for a snowman and plowing into him, causing Henry to beat him to a pulp, is possibly why Professor Otto did not return for another strip.
