George P. Seiler

Project Gutenberg lists a single work by this author: At Hotel On-de-Blink: An entertainment in two parts. The text is also preserved in digitized library copies, which identify it as a play published in Boston by Walter H. Baker & Co. in 1916.

From the surviving editions, George P. Seiler seems to have written light theatrical entertainment rather than a novel—something designed for performance, with comic situations centered on the bustle of a quirky hotel. Beyond that, reliable biographical details are scarce in the sources I could confirm, so it is safest to let the work itself stand in the spotlight.
