He was born at Chew Magna, Somerset, in 1816, the son of an old sailor who had turned showman.
The venture was successful, and the brothers, who had been interested spectators of the equestrian performances at Astley's Amphitheatre, London, then started touring the country with a circus entertainment consisting of a horse and pony and three or four human performers.
This enterprise was a success from the beginning, and in due course John and George Sanger became lessees of the Agricultural Hall, London, and there produced a large number of elaborate spectacles.
[1] In 1871 the Sangers leased Astley's Amphitheatre where they gave an equestrian pantomime every winter, touring in the summer with a large circus.
John Sanger died while touring, at Ipswich, the business being continued by his son.
