Plaque: National Provident - north
The foundation stone in the south-west corner was laid on 10th September 1959 by Lawrence Emlyn Douglas Bevan, Chairman, to mark the rebuilding of the office of the National Provident Institution for mutual life assurance on the site occupied since March 1843.
W. Antony S. Lloyd - Architect
The foundation stone to which this plaque refers reads "National Provident Institution for Mutual Life Assurance. This stone was laid on the 10th September 1959 by Lawrence Emlyn Douglas Bevan, Chairman". Near this stone below the first floor windows the building is inscribed, twice, "Est.1835".
Site: William Curtis & National Provident (3 memorials)
EC3, Gracechurch Street, 48 - 51
The two NPI plaques are in the doorway on the right, at no 48; the Curtis plaque is to the left at no 51. NPI have made rather excessive use of plaques and inscriptions on their building, as if they think their history will fly away if they don't pin it down in the stone.
Strange co-incidence here. The architect of the NPI building (named on the north plaque) had a close familial and professional relationship with a Mr William Curtis Green. Next door, 200 years earlier, lived a Mr William Curtis. Spooky.
