John Bradford, English reformer, prebendary of St. Paul's (born 1510)

John Bradford (1510–1555) was an English Reformer, prebendary of St. Paul's, and martyr. He was imprisoned in the Tower of London for alleged crimes against Queen Mary I. He was burned at the stake on 1 July 1555.

The English Reformation began in 16th-century England when the Church of England broke away first from the authority of the pope and bishops over the King and then from some doctrines and practices of the Catholic Church. These events were part of the wider European Reformation: various religious and political movements that affected both the practice of Christianity in Western and Central Europe and relations between church and state.

A prebendary is a member of the Catholic or Anglican clergy, a form of canon with a role in the administration of a cathedral or collegiate church. When attending services, prebendaries sit in particular seats, usually at the back of the choir stalls, known as prebendal stalls.

Old St Paul's Cathedral was the cathedral of the City of London that, until the Great Fire of 1666, stood on the site of the present St Paul's Cathedral. Built from 1087 to 1314 and dedicated to Saint Paul, this building was perhaps the fourth such church at this site on Ludgate Hill, going back to the 7th century.
