Ford Prefect
From Memory Alpha, the free Star Trek reference
Ford Prefect was the product manager for the artificial intelligence division of the Sirius Cybernetics Corporation.
Prefect's signature was on a certificate naming Ira Graves as "humanoid of the year" in gratitude for his contributions to the Proxima Centauri Interplanetary Bowling League (and also their marching band). (TNG: "The Schizoid Man")
Prefect's name was only visible on a piece of background artwork decorating the set of Graves's office. The certificate, as it appeared on-screen, is printed in The Continuing Mission, a reference work
The name Ford Prefect is an obvious reference to The Hitchhiker's Guide to the Galaxy.
