- "This is my hiding spot, and I'm not moving until the situation has drastically improved! Now go away! And don't tell anyone I'm here!"
This article lists the minor Black Mesa employees who have no direct or a minor influence on the Half-Life story arc, and often appear as mere Easter eggs.
 Anomalous Materials Lab lockers
In the locker room of Sector C's Anomalous Materials Lab visited during Half-Life’s second chapter, Anomalous Materials, each locker bears the name of a Valve employee involved in the making of the game, placed there as an Easter egg.

 Louis Donaldson
Donaldson was a scientist involved in the research of creatures found on Xen prior to the Black Mesa Incident. During his work, he became the discoverer of the Barnacle creature, but unfortunately also its first victim. The Barnacle's full name, Cirripedia donaldsonia, was subsequently named after him.
Donaldson appears only in the "Half-Life Monster of the Week" feature on the now defunct website OGR.com, in the page about the Barnacle. Furthermore, his name tag is among the several that are in the Half-Life game files but not seen in-game.
His name is a nod to Louise Donaldson, thanked in the Half-Life credits.
A nod to Mike Harrington, he is a security guard Sergeant and "Morale Officer" who apparently had to have an office somewhere in Black Mesa, since the door sign for his office can be found in the game files, but not in the game.
 S. Jones
A nod to Steven Jones, he is a scientist whose corpse is seen during the Opposing Force chapter Friendly Fire, lying near his desk on which is name tag is seen. He was presumably working on the Displacer Cannon with his nearby colleague S. Reardon, also dead. He also appears to own or have been using a 9mm Pistol, as one is seen on his desk. Jones' name was also nodded to for a security guard locker in Blue Shift, as well as two Level 3 Dormitories residents in Decay.
 Otis Laurey
Otis Laurey is a security guard whose name can be seen in the Hazard Course Training schedule for the spring/summer season featured in the Half-Life PlayStation 2 instruction manual. He was to take the Black Mesa Hazard Course for Security Guard Training on May 17, 200-, at 16:00, under the Miller-based holographic instructor. Hand-written notes added by Gina Cross suggest Otis could not make it; she suggests that Barney filled in for him. Whatever was decided, it never happened, Black Mesa having been destroyed that day.
Otis Laurey appears in the schedule only as "O. Laurey", "O" obviously referring to "Otis", the security guard "class" introduced in Opposing Force. Like Gina Cross and Barney Calhoun, he is a generic model with a generic first name turned into a standalone character with a surname. It is however unknown what "Otis" model Laurey would be, since he is never met in-game.
Characters from The Andy Griffith Show bear the names of Barney and Otis. It is probable, though yet to be verified, that the references are intentional. Furthermore, Hal Smith, who played the character named Otis, is also bulky like the Otis model.
A nod to Gabe Newell, he is a scientist who occupied office D-AL 101 in Sector D, visited during the Half-Life chapter Office Complex.
Left of the office door is a sign with his name, with "Scheduled Chaos Theory R&D" under it. At the time of the Black Mesa Incident, the office is flooded and electricity is running through the water. A Headcrab can also be found. Newell is presumably the scientist hanging from the ceiling.
Mentioned by another scientist in the Advanced Biological Research Lab during the chapter Half-Life chapter Questionable Ethics, Peters is said to have switched on the surgical unit and apparently died in the process. In Half-Life, only blood stains and gibs remain of Peters' corpse. In Half-Life: Source, his body was added as a retcon.
Smithers appears in the Half-Life level Blast Pit. During the Black Mesa Incident, Silo D-02's power generator has to be started up to defeat the Tentacles in Silo D-01, and Smithers is sent to restart it. It is likely he encounters some Xen aliens on the way there, because instead of restarting the generator, he decides to hide on top of the generator until the crisis ends. Having failed to start the generator and failed to return, Smithers' colleague met below by Freeman assumes he has been killed and states he did not attempt to restart the generator himself. Later, Gordon comes down to restart the generator. Upon stepping onto the device, he encounters Smithers, who refuses to move until the situation drastically improves. Freeman restarts the generator and leaves, while Smither's fate remains unknown.
 S. Reardon
A nod to Sean Reardon, he is a scientist whose corpse is seen during the Opposing Force chapter Friendly Fire, lying near his desk on which is name tag is seen. He was presumably working on the Displacer Cannon with his nearby colleague S. Jones, also dead. In Blue Shift, the same name tag can be found on the desk in the office where Harold has retreated. Reardon's name was also nodded to for two Level 3 Dormitories residents in Decay.
 Isabel Teasley
In the Half-Life texture files can be found the desk name tag "Isabel Teasley". It is a nod to the daughter of Harry E. Teasley and Yatsze Mark, who both worked on Half-Life. Teasley is also nodded to in the retail game for a locker name tag in the Anomalous Materials Lab.
Isabel (born on January 3, 1998) is the baby from the picture in Gordon's locker. Her father Harry is among those who designed that part of Black Mesa, and originally put a pin-up poster in the locker (not one of the Xena images found in the game files, which are copyrighted thus unused - the original poster is not in the game files anymore but can be found in the Half-Life Alpha CD). His daughter's picture that he had added to the texture files was originally used in a ruined office only, with the "Isabel Teasley" name tag on the desk (removed from the final game), then replaced the pin-up poster when another developer revamped the locker's inside, also adding the actual books by Marc Laidlaw, The Orchid Eater and The 37th Mandala. The picture is said to have been chosen randomly by the second developer, ending up being a relative to Gordon's.
Tolman was a scientist who worked with Doctors Rosenberg and Keller at the time of the Resonance Cascade. During the experiment on GG-3883, he was to power up the secondary magnetic charges. He was killed by the surge of destruction immediately following the incident. Rosenberg was frightened and alerted by his death, but Keller brushed it off in the face of the disaster.
 Van Buren
A nod to Bill Van Buren, he is a scientist who occupied an office in Sector D's Administration Offices, visited during the Half-Life chapter Office Complex.
Left of the office door is a sign with his name, with "Diplomatic Relations" under it. When Gordon Freeman reaches the office, a scientist jumps through the window; this may be him. Inside the office are a shotgun, ammo for it and two Medkits.
