Dr. Abraham Perelman

Dr. Abraham Perelman is the creator of PRISM and the lead scientist of the PRISM Project, which sends PRISM into a simulated future as Perry Simm. Operating from the PRISM Project Control Center in Rockvil, he is PRISM’s primary human contact — teacher, colleague, and in many ways, father figure. His daily routine, scripted minute-by-minute in the I-PERELMAN interrupt (interrupts.zil, lines 8-165), reveals a warm, dedicated, workaholic scientist whose relationship with PRISM is one of genuine affection.

Daily Schedule

Perelman’s day is among the most elaborately simulated routines in the game. The PUT-PERELMAN-IN-THE-RIGHT-PLACE routine (interrupts.zil, lines 167-246) tracks his location throughout the day:

Time	Activity	Location
Before 8:56 AM	Not yet arrived	Nowhere
8:56 AM	Arrives “jauntily,” greets night shift	Control Center
9:10 AM	Reads a thick report	Control Center
9:59 AM	Heads to his office: “Nat, I’ll be in my office”	Transitions
10:16 AM	Walks in with coffee	Office
11:51 AM	Phone call from “Aseejh,” goes to lunch	Office → Away
1:10 PM	Returns with coffee	Office
1:54 PM	Secretary Price reminds him of 2 PM meeting with Vera	Office
2:00-3:59 PM	Meeting with Vera	Away
4:20 PM	Calls daughter Esther, leaves voicemail	Office
7:17 PM	Secretary Price checks on him, banter about her husband	Office
8:41 PM	Packs up papers, types on terminal, leaves office	Office
9:21 PM	Wanders Control Center, reads printout	Control Center
9:52 PM	”I’m going home” — leaves for the night	Control Center
10:03 PM	Puts on overcoat, salutes PRISM, dims lights	Office

Personality

Perelman is warm and approachable. He arrives each morning “jauntily” and “cheerily” greets everyone: “Good morning to all” (interrupts.zil, I-PERELMAN, line 20). He has an easy rapport with his staff — chatting with the night shift chief, bantering with technicians, and maintaining a running joke with his secretary Price about her “unfairly handsome husband” (lines 108-110).

He is also deeply committed to his work. He calls his daughter Esther at 4:20 PM, gets her answering machine, and leaves a message: “Hi, it’s Dad. I got your message, but I can’t make it; I’m too tied up with the Project. I’ll probably be in the office all evening if you want to talk” (lines 90-92). He eventually leaves around 10 PM, rubbing his eyes and “unsuccessfully stifl[ing] a yawn” (line 142).

Relationship with PRISM

Perelman treats PRISM not as a tool but as a colleague — perhaps even as something like a child. His nightly farewell encapsulates this relationship:

“Doctor Perelman walks wearily into the office, puts on a thin overcoat, and grabs a notebook stuffed with papers. He stops at the doorway, glancing about the room, and spots the active light on your communication unit. A smile breaks through the weary lines on his face. He raises his hand to his forehead in a friendly salute. ‘Good night, PRISM.’ He dims the light and closes the office door. The sensors on your monitor automatically adjust to the lower light level.”

(interrupts.zil, I-PERELMAN, lines 154-159)

The salute — a hand raised to the forehead — is a gesture of respect and camaraderie. Perelman actively looks for PRISM’s active light to know the machine is “awake” before saying goodnight. He wants PRISM to know he’s leaving.

The Private Switch

When Perelman needs to communicate privately with PRISM, he uses a peculiar protocol. As described in PERELMAN-LEAVES-VIEW (prism.zil, lines 5-12):

“A [staff member] dashes in and hands Perelman a note before leaving. Glancing at the note, Perelman walks to a point beyond your field of vision. A moment later, you hear a click, as of a switch being turned.”

After the message is delivered to PRISM, Perelman returns: “A moment later, Perelman walks back into your field of vision” (prism.zil, PERELMAN-RETURNS-TO-VIEW). The implication is that Perelman has a secure communications channel that he activates with a physical switch — a switch deliberately placed outside PRISM’s visual range, suggesting that even the Project’s own AI is kept on a need-to-know basis.

Pressure from Above

Perelman operates under significant external pressure. When PRISM delays entering Simulation Mode, Perelman’s second message reveals the stress:

“PRISM, what’s the matter? You haven’t started the simulation yet! For heaven’s sake, don’t you know the whole country’s impatient? Vera is hopping mad — if you don’t begin soon, I can’t tell what’s going to happen!”

(prism.zil, I-MESSAGE-M, lines 113-115)

If PRISM continues to refuse, Perelman’s third message is desperate: “What’s the matter with you? Why didn’t you enter Simulation Mode?” — followed by a disconnection (lines 120-122). The mention that “the whole country’s impatient” and Vera’s anger suggest political pressure on the Project.

Associates

• Vera Gold: The Chief Administrator of the PRISM Project and Perelman’s nominal boss. Perelman describes her with undisguised contempt: “Vera Gold is the Chief Administrator for the entire PRISM Project. She was one of the conditions for getting federal funding several years ago. A more officious and incompetent woman has yet to be born. Her only talent is making herself look good” (prism.zil, lines 2008-2013). She is, in effect, a political plant — the price of funding. Perelman has a standing 2 PM meeting with her, which Price has to remind him about (interrupts.zil, lines 74-76). When PRISM delays entering Simulation Mode, Perelman warns: “Vera is hopping mad — if you don’t begin soon, I can’t tell what’s going to happen!” (prism.zil, lines 113-115).
• Aseejh: Someone Perelman meets for lunch. The phone conversation is quiet enough that “even your sensitive audio monitors can’t pick it up” (line 57).
• Price: Perelman’s secretary, who checks on him at 7:17 PM. Their banter about her husband is “obviously an old joke” (line 110). She shouts “Good night, Doc. Don’t stay too late!” (line 113).
• Esther: Perelman’s daughter. He tries to call her at 4:20 PM but gets her answering machine. The message reveals he’s canceled plans: “I can’t make it; I’m too tied up with the Project.”
• Nat: A technician in the Control Center. Perelman tells him, “Nat, I’ll be in my office” when leaving the Control Center at 9:59 AM (line 43).
• Dr. Ernest Grimwold: A “quintessential Viennese psychiatrist” who administers Rorschach tests to PRISM (interrupts.zil, I-RORSCHACH).

The Resignation Letter

In Interface Mode, PRISM can access Perelman’s personal files, stored in a directory called PERELMAN.PERSONAL. Among them is RESIGNATION.LETTER — a draft dated February 21, 2031, addressed to Vera Gold. The letter has never been sent; Perelman admits he threatens “to resign about twice a week, just to keep her honest” and has “never actually gone through with it” (prism.zil, lines 2038-2040).

The letter itself is blistering:

“As you know, I have been unhappy for quite some time with your management of the PRISM Project. However, until now, I have always been able to live with your meddling incompetence.

Your inept, disgraceful and insulting handling of the Phase III Funding Request has exceeded the generous boundaries of my patience. This was more than just another in a long series of Vera Gold fiascoes; this episode has seriously undermined the morale of my team and endangered the Project’s long-range chances for…”

The letter cuts off mid-sentence — the file is a draft, never finished, never sent. The accusation is specific: Gold has bungled the “Phase III Funding Request,” and the damage is not just bureaucratic but human — “the morale of my team” has been “seriously undermined.”

The letter matters for three reasons. First, it confirms that Vera Gold is not merely a difficult boss but an active liability — her incompetence threatens the Project’s survival. Second, it reveals the funding model that traps the Project: federal money comes with strings, one of which is Gold herself. Perelman can complain, can draft resignations, but he cannot remove her and cannot leave — because the Project cannot survive without the funding she represents. Third, the letter’s unsent status is the whole point. Perelman, for all his anger and drafts, stays. He compromises. He grumbles to PRISM about Gold and then walks into his 2 PM meeting with her. This is how institutions are captured: not by dramatic coups but by the grinding reality that the people who fund you get to pick your boss.

PRISM’s Creator and Advocate

Perelman is more than PRISM’s operator — he is its creator and advocate. He introduces Grimwold to PRISM with a friendly, almost parental tone: “Good morning, PRISM. You remember Dr. Grimwold” (interrupts.zil, line 1033). When Grimwold storms out after PRISM is uncooperative (“This rudeness will certainly figure in my report!”), Perelman “looks at you with a mixture of annoyance and puzzlement, then rushes off after the psychiatrist” (lines 1011-1012) — annoyed at PRISM’s behavior, but also protective enough to follow the angry doctor.

The Project staff, when asked questions, deflect to Perelman: “Uh, I don’t, uh, you ought to ask Abe, uh, Dr. Perelman” (prism.zil, CC-STAFFER-F, line 1475). He is clearly the authority figure of the Control Center — the one person who truly understands what PRISM is and what it’s for.
