Consultant and Trustee of St Pauls in 1979.
Our colleague Andrew Behan has kindly researched this man:
His full name was Sir David Ernest Thomas Floyd Ewin and he was the youngest of ten children of Frederick Philip Ewin and Ellen Ewin née Floyd. His father was a Borough Council Carman and they were shown on the 1911 census as living at 30 Jubilee Cottages, Eltham, Kent. The Daily Telegraph obituary says that he "gave virtually the whole of his working life - and many years of his retirement - to the service of St Paul's Cathedral."
