Character guide

Dr. Gall

major

Also known as Doctor Gall, Gall

Dr. Gall runs the physiology department at Rossum's, the man who decides what a Robot's body can feel and endure. Acting on Helena's plea to make the Robots 'more like us,' he quietly alters their irritability for his own satisfaction, a secret he carries while the others boast of their foresight. His experiment is the hinge on which the factory's confidence turns: what he did in private becomes the question everyone must answer when the world outside stops sending letters.

Harry Domin

major

Also known as Domin, Mr. Domin, Harry

Domin presides over the factory, dictating orders to Southampton and Hamburg and welcoming Helena Glory with the ease of someone who believes he has no secrets worth keeping. He loves Helena, yet he cannot hear her fear: when she begs him to close the works and flee, he calls the revolts and wars 'passing troubles' bound to precede a new order. His unshakable self-confidence is the play's central irony, and the early scenes plant every reason it will be tested.

Helena Glory

major

Also known as Helena, Miss Glory, Madame Helena, Madame Domin

Helena comes to the factory as an outsider with a cause, warning Domin that she intends to rouse the Robots, and ends up his wife ten years later in the same room. Haunted by the 'cruel strangeness' between humans and Robots, she asked Dr. Gall to give them a physiological correlate of soul, hoping they could not hate what resembled them. Her tenderness is both the play's conscience and its quietest incitement, and she is the one who finally names Gall's secret aloud.

Alquist

major

Also known as Mr. Alquist

Alquist oversees the factory's construction department, a practical man among visionaries who measure the world in orders and output. In the besieged drawing-room he sits apart, listening to Helena's Rachmaninoff while the others calculate volts and barricades, and his small gratitude for the music marks him as the one who values what cannot be manufactured. His presence in the early–middle arc grounds the play's abstractions in the plain dignity of making things that last.

Radius

major

Radius is the Robot whose rebellion gives the play its menace, the one whose dissatisfaction spreads through the ranks until the factory is ringed by identical faces. In the besieged house he is felt more than seen: the Robots stand beyond the railing in monstrous silence, waiting, and Gall admits their sameness makes the sight a nightmare. Radius embodies the question the humans keep dodging—what happens when the made thing stops consenting to be used.

Busman

supporting

Also known as Consul Busman

Busman handles the commercial side of R.U.R., the man who turns Robots into invoices, shipping terms, and part payment in coal. He is the play's pragmatist, quick to ask Gall when the experiments began and how many Robots were altered, as if the answer could be filed. His business-as-usual instinct in the early acts sharpens the irony of a company that has sold its own replacement and cannot yet read the silence on the other end of the wire.

Fabry

supporting

Fabry is the hands-on technical mind of the factory, the man who lays cable, barricades stairs, and keeps the electrical works burning as the last proof that humans still function. Where Domin strategizes and Gall broods, Fabry measures survival in volts and live wires. His competence gives the besieged household its only real defense, making him the quiet counterweight to the play's gathering helplessness.

Hallemeier

supporting

Hallemeier oversees the training of Robots, yet in the crisis he is the one stacking barricades and admitting, with a soldier's bluntness, that there's a feeling of death about it all. He is practical, a little sentimental, and openly moved by Helena's piano drifting through the shuttered house. His tenderness toward music and his grim readiness to fight sit side by side, showing how the men who built this world still cling to its graces.

Sulla

supporting

Sulla works among the humans as a typist, one of the manufactured beings whose labor the whole Rossum enterprise depends on. Her place in the domestic world keeps the Robots visible as workers rather than abstractions, so that the later uprising reads as the return of something familiar rather than alien. She embodies the ordinary, unremarkable presence of Robots in human life—exactly the ordinariness the play will make unbearable.

Nana

minor

Helena's elderly nurse and maid, skeptical of robots.

Primus

supporting

Primus is a Robot made on the same day as Helena, and when Alquist threatens to dissect her, he offers his own life instead and threatens to kill the man who would take her. His protectiveness, his jealousy of her touch, and his refusal to live without her are the first unmistakably human feelings the play allows a Robot to voice. He matters because he turns the question of Robot humanity from argument into flesh—and because Alquist, watching him, names him and Helena Adam and Eve.

Helena (Robot)

supporting

Also known as Helena Primus

Helena is a Robotess who shies away from Alquist's touch, smooths Primus's hair, and asks what use beauty is—yet she weeps, and her tears are the thing Alquist cannot explain away. She and Primus belong to each other with a devotion that has no place in a factory's ledger, and she would walk into the dissecting room rather than be parted from him. Her timidity and her defiance together make her the play's clearest sign that the Robots have become something their makers never intended.

Old Rossum

minor

Also known as Rossum, old Rossum

The original scientist who discovered the secret of creating artificial life.

President Glory

minor

Helena's father, president of the Humanity League mentioned but not appearing on stage.

Marius

minor

Also known as Marius R. C.

A robot servant in Domin's household.

Young Rossum

minor

Also known as young Rossum

Old Rossum's nephew who turned the discovery into a commercial product.
