Book store assistant

Biography
The library assistant was a female orangutan who worked as an indentured servant to a librarian at 175 Broadway in some unspecified California city of the near future (possibly San Francisco).

Although the organgutan was a seemingly competent assistant she, like most apes, was illiterate and did not always perform to the librarian's expectations. She admonished the assistant's inaccurate book retrieval skills by intoning the ubiquitous command of displeasure, "No!"

Notes & Trivia
The character of the library assistant was created by director J. Lee Thompson and writer Paul Dehn, based on concepts originally developed by author Pierre Boulle and film producer Arthur P. Jacobs.
