The AA is saddened to report that Rick Mather died Saturday 20 April after a short illness. Graduate of the AA urban design course (1966), Rick taught a first year unit with fellow American Dale Benedict 1974-77. He set up Rick Mather Architects in 1973, specialising on design and master planning for cultural and academic institutions.

In 1980 he was commissioned a phased restructuring of various AA spaces, including the existing bar, kitchen, exhibition gallery and toilets, and the former photo library, drawing materials shop, triangle bookshop and crèche. Amongst many celebrated projects, the refurbishment of Dulwich Picture Gallery, an extension to the National Maritime Museum in Greenwich and a masterplan for the South Bank Centre, all from 1999, helped place his practice in the International architectural scene. Their work on the Ashmolean Museum in Oxford was nominated for the Stirling Prize in 2010.

He served as AA Councillor 1992-96 and remained an active AA Member.
