Henry Filmer was a 16th century English Protestant martyr, one of the Windsor Martyrs, during the reign of Henry VIII.
Filmer was a Protestant tailor and church warden of St John's Church at Windsor who complained about the overly Catholic sermons of the vicar.[1] He gained the support of the Bishop of Salisbury much to the consternation of a former Catholic mayor of the town, William Simonds.[1] His powerful friend, Dr John London, who was Bishop Gardiner's agent, arrested Filmer, along with four others,[1] and, on 4 August 1543, he, Robert Testwood and Anthony Pearson were burnt to death.[2]
