Thomas Dagger, a 17th century journeyman baker, only became famous rather recently when new research identified him as the first witness to one of the seminal events in London’s history – the Great Fire of 1666.

The research was undertaken by Professor Kate Loveman at the University of Leicester for the Museum of London and will be used to inform its gallery displays when it opens its new site at Smithfield in 2026.

Drawing on letters, pamphlets, legal and guild records, Professor Loveman put Dagger, who worked in Thomas Farriner’s bakery on Pudding Lane, at the centre of the the fire’s origin story.

It’s well-known that the fire began in Farriner’s bakery in the early hours of 2nd September, 1666, and went on to consume some 13,200 homes in the city, leaving some 65,000 people homeless. But reports differ as to who was in the bakery when the fire started.

Among accounts pointing to Dagger being present is a letter from MP Sir Edward Harley who wrote in a letter to his wife that Thomas Farriner’s “man” – a term referring to his servant or journeyman – was woken after in the early hours on 2nd September choking from smoke. He reported that Farriner, his daughter and “his man” then escaped out of an upper window, but his maid died.

Dagger’s name is also found grouped with other Farriner household members among witnesses on a subsequent indictment targeting Frenchman Robert Hubert who was convicted and hanged for starting the fire after making a somewhat dubious confession.

Professor Loveman concludes that, based on her research, Thomas Dagger was the first witness to the Great Fire of London, woken by choking smoke shortly before 2am on 2nd September. Aware of the fire, he then alerted other members of the household before, along with his boss Thomas Farriner, Farriner’s son Thomas Farriner, Jr, and Farriner’s daughter Hanna, escaping by climbing out of an window. An unnamed maid who was in the house did not escape with them and was killed.

Professor Loveman’s research further showed that Dagger arrived in London from Wiltshire in 1655 and was apprenticed to one Richard Sapp for nine years but ended up serving part of that time with Farriner. Soon after the fire, in 1667, he took his freedom and by January the following year had married and had a baby. He went on to establish his own bakery at Billingsgate.

Says Professor Loveman: “It was fascinating to find out more about what happened on that famous night. Although most of the evidence about the Farriners is well known to historians, Thomas Dagger’s role has gone unrecognised. Unlike the Farriners, his name didn’t become associated with the fire at the time. Soon after the disaster, he merges back into the usual records of Restoration life, having children and setting up his own bakery. His is a story about the fire, but also about how Londoners recovered.”
