He spent most of his life living and working in the Valley of Four Drafts as a mechanical instructor at the V.F.D. Headquarters. It is said that the one thing that could put him in a good mood was a "particularly promising mechanical student." Mr. Kornbluth was a quiet and mysterious man, and no one had ever known who he was, where he came from, or what the "C" or the "M" stood for. He always carried a paper bag of pistachios in his pocket and spent much of his spare time holed up in his dormitory room, writing strange stories, or gazing sadly out the windows of the kitchen. He is said by Lemony Snicket to have died in a fire.
- Both his name and his hobby of "writing strange stories" are references to science fiction writer Cyril Michael Kornbluth.

- The Slippery Slope (Mentioned only)
- Mr. Snicket says in The Slippery Slope that Kornbluth and his pistachios were burned
