Spring Heeled Jack (also Springheel Jack, Spring-heel Jack, etc), is a character from English folklore said to have existed during the Victorian era and able to jump extraordinarily high. The first claimed sighting of Spring Heeled Jack that is known occurred in 1837. Later alleged sightings were reported all over England, from London up to Sheffield and Liverpool, but they were especially prevalent in suburban London and later in the Midlands and Scotland.
Many theories have been proposed to ascertain the nature and identity of Spring Heeled Jack. The urban legend of Spring Heeled Jack gained immense popularity in its time due to the tales of his bizarre appearance and ability to make extraordinary leaps, to the point where he became the topic of several works of fiction.
Spring Heeled Jack was described by people claiming to have seen him as having a terrifying and frightful appearance, with diabolical physiognomy that included clawed hands and eyes that "resembled red balls of fire". One report claimed that, beneath a black cloak, he wore a helmet and a tight-fitting white garment like an "oilskin". Many stories also mention a "Devil-like" aspect. Spring Heeled Jack was said to be tall and thin, with the appearance of a gentleman, and capable of making great leaps. Several reports mention that he could breathe blue and white flames and that he wore sharp metallic claws at his fingertips. At least two people claimed that he was able to speak in comprehensible English ....
Though the Lord Mayor seemed fairly sceptical, a member of the audience confirmed, "servant girls about Kensington, Hammersmith and Ealing, tell dreadful stories of this ghost or devil". The matter was reported in The Times on 9 January, and other national papers on 10 January, and the day after that (January 11) the Lord Mayor showed a crowded gathering a pile of letters from various places in and around London complaining of similar "wicked pranks". The quantity of letters that poured into the Mansion House suggests that the stories were widespread in suburban London. One writer said several young women in Hammersmith had been frightened into "dangerous fits", and some "severely wounded by a sort of claws the miscreant wore on his hands". Another correspondent claimed that in Stockwell, Brixton, Camberwell and Vauxhall several people had died of fright, and others had had fits; meanwhile, another reported that the trickster had been repeatedly seen in Lewisham and Blackheath.
The Lord Mayor himself was in two minds about the affair: he thought "the greatest exaggerations" had been made, and that it was quite impossible "that the ghost performs the feats of a devil upon earth", but on the other hand someone he trusted had told him of a servant girl at Forest Hill who had been scared into fits by a figure in a bear's skin; he was confident the person or persons involved in this "pantomime display" would be caught and punished. The police were instructed to search for the individual responsible, and rewards were offered.
