Until that date there was only one known spring in Leamington, on land belonging to the 4th Earl of Aylesford, who refused to sell the water (which was used for bathing and medicinal purposes), instead allowing people to have it for free.
However, in 1784 Satchwell and his friend William Abbotts found a second spring and in the manner of the time used its supposed medicinal qualities to make money from the leisured classes.
The charity was to help the sick poor, who were to provide a certificate of need from a respectable person or parish officer, entitling them to a weekly lodgings allowance of 5s, subject to medical supervision.
He died of a chest condition and was buried in Leamington's parish church, All Saints on 4 December 1810,[2] just yards from where his friend Abbotts had been laid to rest four years earlier.
Two years after his death, Satchwell was to be honoured as a 'patron and friend' of the town, given a raised tomb fit for a nobleman or gentleman in the churchyard of All Saints.
