Conservative politician in the City of London, associated with the Candlewick Ward and the Worshipful Company of Gardeners. Lord Mayor of London 1936-7. MP for the City of London 1938 -1945.
Also a property developer: in 1933, he acquired a Queen Anne building, Lichfield House, in Richmond which he demolished and replaced by two blocks of flats, Lichfield Court, totalling 211 flats in all. These were built in the Art Deco style and are now Grade II listed.
The photo, marked up for publication, shows Broadbridge with his wife. It's not dated but the necklace is not the mayoral chain so we think it predates 1936.
