Jonathan Strong (c. 1747/8–1773) was an enslaved person and subject of one of the earliest legal cases relating to slavery in Britain and the British abolitionist movement.
It is not known where Strong was born, but he was brought to Britain from the British colony of Barbados by a Barbadian lawyer and slave trader, David Lisle.
[1] The Sharps paid for his treatment and, when he was fit enough, found him employment as an errand runner with a Quaker apothecary friend of theirs[3] at a building near William's office.
Viewing Strong as his property, Lisle sold him to a Jamaican slave trader, James Kerr, and had him kidnapped and placed in a city jail.
Sharp, at the suggestion of Thomas Beech, the Coroner of London, threatened to charge Laird with assault should he attempt to take Strong by force.
