Mad scientists of Stanisław Lem

Mad scientists appear in fiction of Stanisław Lem in the memoirs of Lem's starfaring vagabond Ijon Tichy, collected in The Star Diaries and Memoirs of a Space Traveller. They include professors Corcoran, who created several artificial universes in isolated lockers; Decantor, who created an immortal soul, Zazul, who cloned himself and was apparently killed by the clone who took his place; Diagoras, who created progressing makes of an "independent and self-perfecting device that is capable of spontaneous thought" and was unwittingly used by the two of them as a communication media; doctor Vliperdius, who is a robot doctor who runs an asylum for mentally ill robots; and professor A. Dońda, who catastrophically succeeded in his quest to prove mass-information equivalence, analogous to mass–energy equivalence.
