"The Up-to-Date Sorcerer" is a science fiction short story by American writer Isaac Asimov.
It was first published in the July 1958 issue of Magazine of Fantasy and Science Fiction and reprinted in the 1969 collection Nightfall and Other Stories.
Requested and encouraged by editor Anthony Boucher, the story is a deliberate attempt by the author to write something humorous that incorporates his love of the complex yet logical plots found in the Gilbert and Sullivan operas.
Johns' students, Alice Sanger and Alexander Dexter, become entangled in philtre-induced promises of marriage.
The narrator theorizes that the ending to The Sorcerer was not the original one, but was forced on Gilbert by Victorian mores.
