They thought he had died – but Nazi jail 'victim' lived until 1989

Researchers have confirmed that Walter Dauny – one of the 22 people named on the Lighthouse Memorial outside the Maritime Museum – survived imprisonment in France during the Second World War, dying in London in 1988.

His name, which was incorrectly engraved at the site as ‘John Dauny’, will now be removed from the memorial and further work will be done to check that there are no other changes that need to be made.

The error was discovered when Mr Dauny’s relatives in the UK heard there was someone with the Dauny surname on the commemoration.
