The entertainment came of age during the era of the music hall in the United Kingdom and vaudeville in the United States. George Sutton began to incorporate a puppet act into his routine at Nottingham in the 1830s, but it is Fred Russell who is regarded as the father of modern ventriloquism. In 1886, he was offered a professional engagement at the Palace Theatre in London and took up his stage career permanently. His act, based on the cheeky-boy dummy "Coster Joe" that would sit in his lap and 'engage in a dialogue' with him was highly influential for the entertainment format and was adopted by the next generation of performers. (A blue plaque has been embedded in a former residence of Russell by the British Heritage Society which reads 'Fred Russell the father of ventriloquism lived here').
