The American Academy of Arts and Letters named the winners of its 2010 architecture awards Tuesday, which were dominated by northeastern designers. Long-time GSD professor Michael Van Valkenburgh is the recipient of the Arnold W. Brunner Memorial Prize in Architecture. The annual award of $5000 has been given to preeminent architects since 1955, ranging from Louis Kahn to Elizabeth Diller. Van Valkenburgh has designed more than 350 landscapes, including the recently opened Brooklyn Bridge Park. The Academy also announced the winners of its Academy Awards in Architecture, for strong personal work, which go to New York’s planning-obsessed Architecture Research Office and the Afterpartying MOS, of New Haven and Cambridge. And City College architecture dean, critic, and designer Michael Sorkin also won an Academy Award, largely for his writing. The four winners beat out 50 nominees and were selected by academy members Henry Cobb, Hugh Hardy, Steven Holl, Laurie Olin, Billie Tsien, and Tod Williams.
