The Day of the Boomer Dukes is a science fiction short story by Frederik Pohl first published in 1956.
A bored resident of the future, reading a crime magazine from the 1950s, decides to time travel back to the 20th century with a suitcase full of weapons and offer his services to the Mafia. Just for a little excitement.
Just as medicine is not a science, but rather an art--a device, practised in a scientific manner, in its best manifestations--time-travel stories are not science fiction.
Time-travel, however, has become acceptable to science fiction readers as a traditional device in stories than are otherwise admissible in the genre.
Here, Frederik Pohl employs it to portray the amusingly catastrophic meeting of three societies.
The Day of the Boomer Dukes was first published in Future Science Fiction No. 30 1956.
