John Lambert (died 1538) was an English Protestant martyr burnt to death on 22 November 1538 at Smithfield, London.
Lambert was born John Nicholson in Norwich and educated at Queens' College, Cambridge, where he became a friend and a colleague of Thomas Cromwell.
In 1536 he was accused of heresy by the Duke of Norfolk, but escaped until 1538, when he was put on trial for denying the real presence of Christ in the bread and wine of the Eucharist, the doctrine of transubstantiation.
[2] Lambert was eventually burned at the stake, whilst Thomas Cromwell purportedly watched and cried for the duration.
"[3] Ben Price portrayed Lambert in season 3 of Showtime's television show The Tudors.
