Theresa Berkley

Theresa Berkley or Berkeley (died September 1836) was a 19th-century English dominatrix who ran a brothel in Hallam Street, just to the east of Portland Place, Marylebone, London, specialising in flagellation. She is notable as the inventor of the "chevalet" or "Berkley Horse", a BDSM apparatus.

Theresa Berkley ran a high-class flagellation brothel at 28 Charlotte Street (which is today's 84–94 Hallam Street). She was a "governess", i.e. she specialised in chastisement, whipping, flagellation, and the like. She invented the "Berkley Horse", an apparatus that reportedly earned her a fortune in flogging wealthy men and women of the time. There are no artworks depicting what Theresa Berkley looked like, and occasional descriptions usually report that she was attractive, with a strong disposition. An expert with all instruments of torture, her talents became highly sought after by the of the day. She was a master of the art of inflicting pain for pleasure, and practised absolute privacy to protect her clientele. Her clients were said to have been both men and women of wealth, and her career was financially lucrative. Her fame was such that the pornographic novel Exhibition of Female Flagellants was attributed to her, probably falsely.

One writer said of her:

She possessed the first requisite of a courtezan, viz., lewdness; for without a woman is positively lecherous she cannot keep up the affectation of it, and it will soon be perceived that she moves her hands or her buttocks to the tune of pounds, shillings, and pence.

According to an unnamed source quoted by Henry Spencer Ashbee:

"Her instruments of torture were more numerous than those of any other governess. Her supply of birch was extensive, and kept in water, so that it was always green and pliant: she had shafts with a dozen whip thongs on each of them; a dozen different sizes of cat-o'-nine-tails, some with needle points worked into them; various kinds of thin bending canes; leather straps like coach traces; battledoors, made of thick sole-leather, with inch nails run through to docket, and currycomb tough hides rendered callous by many years flagellation. Holly brushes, furze brushes; a prickly evergreen, called butcher's bush [?butcher's broom]; and during the summer, a glass and China vases, filled with a constant supply of green nettles, with which she often restored the dead to life. Thus, at her shop, whoever went with plenty of money, could be birched, whipped, fustigated, scourged, needle-pricked, half-hung, holly-brushed, furze-brushed, butcher-brushed, stinging-nettled, curry-combed, phlebotomized, and tortured till he had a belly full."
