The British architect Dennis Crompton has died at the age of 89. A founding partner of Archigram (with Warren Chalk, Peter Cook, Ron Herron, David Greene, and Michael Webb), Crompton devoted himself to preserving the group’s legacy after it dissoved in 1975, organizing its archives and disseminating its works in publications and exhibitions, including the major retrospective ‘Archigram – Experimental Architecture 1961-1974,’ held in Vienna in 1994. En 2002, Archigram was awarded the RIBA Gold Medal.
