Бхактисиддханта Сарасвати
This change is believed to have happened largely in India due to the efforts of a particularly adept preacher known as Bhaktivinoda Thakur, who also held the position of a deputy magistrate with the British government. Bhaktivinoda Thakur's son grew up to be both an eminent scholar and a highly influential Vaishnava preacher, and was later known as Bhaktisiddhanta Sarasvati. In 1918, Bhaktisiddhanta Sarasvati founded Gaudiya Math in India, and later sixty-four Gaudiya Matha monasteries in India, Burma and Europe. In 1933, the first European preaching center was established in London (London Glouster House, Cornwall Garden, W7 South Kensington) under the name "Gaudiya Mission Society of London".
