Q: It became fashionable in Britain during the Regency period , having been made respectable by the endorsement of Dorothea Lieven , wife of the Russian ambassador . Diarist Thomas Raikes later recounted that `` No event ever produced so great a sensation in English society as the introduction of the waltz in 1813 '' . In the same year , a sardonic tribute to the dance by Lord Byron was anonymously published ( written the previous autumn ) . Influential dance master and author of instruction manuals , Thomas Wilson published A Description of the Correct Method of Waltzing in 1816 . Almack 's , the most exclusive club in London , permitted the waltz though the entry in the Oxford English Dictionary shows that it was considered `` riotous and indecent '' as late as 1825 . Ann Bronte in ' The Tenant of Wildfell Hall ' has a scene set in 1827 where the local vicar Reverend Milward tolerates quadrilles and country dances but intervenes decisively when a waltz is called for , declaring `` No , no , I do n't allow that ! Come , it 's time to be going home '' .
