G.R. Emlin by Peter Adams.

Ficticious employee G.R. (Grace) Emlin with her genuine Bell Labs employee badge.

GR Emlin makes numerous appearances throughout the history of UNIX at Bell Labs. The fictitious employee was conveniently used as a scapegoat for pranks perpetuated by residents of the UNIX lab. For example, GR Emlin allegedly signed a requisition for spray paint that was used to stencil Peter Weinberger’s face on a nearby water tower.

An inside joke, GR Emlin was also thanked and acknowledged in various documents and books including the manual for the Plan 9 operating system as well as in “C Programming Language” by Brian Kernighan and Dennis Ritchie.
