Published as a 50-page book, the story tells of the invention of the Prospective Telegraph and provides excerpts from a newspaper that it retrieves from a 1977 future dominated by scientific and medical super-nannies.
By this truly wonderful invention (exquisitely simple in its machinery, yet of surpassing power) the obstacle of Time is as effectually conquered as that of Space has been for the last generation by the Electric Telegraph; and future years—even, it is anticipated, future centuries—will be made to respond to our call as promptly and completely as do now the uttermost parts of the earth wherewith the magic wire has placed us in communication. 
Frances Power Cobbe, Master Traveller
I place Frances Power Cobbe as the author of the first science fiction time travel story given that in her book a scientist invents a machine to retrieve information from the future—certainly an accomplishment worthy of a Master Traveller Citation.
