Revd John Trusler (1735–1820) was an eccentric English divine, literary compiler, and medical empiric.
In his tenth year, he was sent to Westminster School, and at the age of fifteen he was transferred to Mr Fountaine's fashionable seminary at Marylebone.
One of these, he says, was 'La Serva Padrona,' or the 'Servant-Mistress,' of Giovanni Battista Pergolesi, performed in Marylebone Gardens in 1757; but it seems that the real translator was Stephen Storace.
He was curate successively of Enford, Wiltshire, of Ware, Hertfordshire, at Hertford, at the Hythe church, Colchester, of Ockley, Surrey, and of St Clement Danes in the Strand, London.
In 1761, Dr Bruce, the king's chaplain at Somerset House, employed him as his assistant and procured for him the chaplaincy to the Poultry Compter.
[4] In 1769, Trusler sent circulars to every parish in England and Ireland proposing to print in script type, in imitation of handwriting, about a hundred and fifty sermons at the price of one shilling each, to save the clergy both study and the trouble of transcribing.
