His entry states that the entrepreneur from Sheffield was “the first club owner to be granted a fully nude licence”. His more conventional nightclubs played host to The Beatles, City bankers and Conservative Party fundraisers.

It continues: “The business model was to get customers intoxicated with overpriced drinks and to empty their wallets and credit cards for various levels of services, some more intimate and in private booths away from public gaze.”

Stringfellow’s entry also describes him, in his own words, as a “sex-mad atheist”.

Oxford University Press has indicated that Stringfellow is not technically the only club owner to be included, with Kate Meyrick, the “Nightclub Queen” of Soho from the Twenties, already in the ODB.

Stringfellow has been added to the latest update, which includes 243 additional biographies of people, especially those who died in 2018, such as Prof Hawking; Lord Ashdown of Norton-cum-Hamdo, the former Liberal Democratic leader; Sir VS Naipaul, the novelist; and Sir Ken Dodd, the comedian.
