Docent H. (1968)

Professor H., obsessed with replacing humans through artificial beings, has created Traumer—an unsettlingly perfect assistant whose cold efficiency conceals an unnatural origin. Believing he has found the ideal subject for his next experiment, the professor plots to transplant Traumer’s brain with that of a distinguished scientist. But the plan unravels when Traumer proves far less obedient, and far more uncanny, than expected.
