[1] Chalk, (John) Warren (1927–1987),[2] architect, was born on 7 July 1927 at 32 Killarney Road, Wandsworth, London, the second of three sons of James Percival Chalk (1887–1962), Unitarian minister, and his wife, Gretchen Elisabeth Stovold, née Brigden (1891–1972).
They made a reputation designing the London Southbank Centre, the Queen Elizabeth Hall, Purcell Room, Hayward Gallery, and the famous 'undercroft', now so popular with skate boarders.
His major contribution was the Archigram magazines, especially Issue 4 with the famous Zoom cover.
[4] Chalk and Herron won various competitions before their involvement with Archigram, notably 'Gasket Homes' was an early success.
He was known as the most critical and abrasive of the Archigram group, questioning the banal, and his interests were broad and eclectic.
